FUNCTIONAL DESCRIPTION - MOTOR TYPE MRD - MRDE - MRV - MRVE
MRD-MRDEFUNCTIONAL DESCRIPTION The outstanding performance of the motor is the result of an original and patented design.
The principle is to transmit force to the driving shaft (2 and 6) by means of a pressurizedcolumn of oil (a) without any connecting rods, pistons, pads and pins.This oil column is contained by a telescopic cylinder (1) with a mechanical connection atthe lips at each end, which seal against the spherical surfaces (3) of the cylinder-head (4)and the spherical surface of the rotating shaft (2). These lips retain their circular crosssection when stressed by the pressure so there is no alteration in the sealing geometry. Thecareful selection of materials and optimized design has minimized both friction and leakage.Another advantage of this design stems from the elimination of any connecting rods, thecylinder can only expand and retract linearly so there are no transverse components of thethrust. This means no oval wear on the moving parts and no side forces on the cylinderjoints.Dual displacement is accomplished by having the eccentric shaft cam free to move radiallychanging its eccentricity. In this way the displacement can be choosen amongst manydifferent values.The radial motion is controlled by means of hydraulic cylinders (5) located in the drive shaft(6). The feeding of the displacement cylinders is accomplished by means of the rotating intake(7). The displacement can be changed even while rotating under full load.
TIMING SYSTEM Timing is accomplished by means of a rotary valve (8) driven by the rotary valve drivingshaft (9) that it is connected to the rotating eccentric shaft. The rotary valve rotates betweenthe rotating intake (7) and the reaction ring (10) which are fixed to the rotary valve housing.This timing system is also of a patented design being pressure balanced and self-compensating for thermal expansion.
EFFICIENCY The advantages of this type of timing system, combined with a revolutionary propulsionsystem, produces a motor with extremely high values of mechanical and volumetricefficiency. The torque output is smooth even at very low speed under high pressure, andthe motor offers high performance starting under load.

MRV 450FUNCTIONAL DESCRIPTION The estreme versatility of this motor is because of two simple but ingenious designs
combined in one machine. The rotation of the shaft is by the same original and patendedmechanism as the MR motor but, in addition, the MRV has an arrangement of internalcylinders to actually change the motor displacement, even while turning under full load.The principle of the rotation mechanism is to transmit the effort from the stator to theeccentric part of the shaft by means of a pressurized column of oil.This oil column is contained by a telescopic cylinder with a mechanical connection only atthe lips at each end which seal against the spherical surfaces of the stator and the rotor.These lips retain their circular cross section when stressed by the pressure so there is noalteration in the sealing geometry. The particular selection of materials and optimization ofdesign has minimized both the friction and the leakage. Another advantage of this designstems from the elimination of any connecting rods, the cylinder can only expand and retractlinearly so there are no transverse components of the thrust.This means no oval wear on the moving parts and no side forces on the cylinder joints.In the MRV motor the eccentric part of the shaft is free to move radially. The radial motionis controlled by two lateral hydraulic cylinders which are an integral part of the shaft.As the eccentricity changes so does the stroke of the telescopic cylinders and hence thedisplacement.The variation is stepless between full eccentricity (maximum displacement) and fullconcentricy. It is possible to insert spacers in the lateral cylinders to limit the maximum andminimum displacements and so tailor the motor to the exact requirements of any application.The facility of variable displacement can be used with hydraulic regulation valves to createa variety of control systems ex. constant pressure operation, constant power operation,two speed operation. When used with electronic regulators even more control system arepossible ex. high efficiency speed control, high efficiency ring main systems, high efficiencytorque control etc.In common with the MR range, this motor has a patented distributor valve being pressurebalanced and self compensating for thermal expansion. The advantages of this type ofvalve coupled with a revolutionary cylinder arrangement produce a motor with extremelyhigh values of mechanical and volumetric efficiency. The torque output is smooth even atvery low speeds and the motor gives a high performance starting under load.

FLUID SELECTION - MOTOR TYPE MRD - MRDE - MRV - MRVE
EXAMPLE: At a certain ambienttemperature, the operating temperature inthe circuit is 50°C. In the optimumoperating viscosity range (v
rec; shaded
section), this corresponds to viscositygrades VG 46 or VG 68; VG 68 shouldbe selected.
IMPORTANT: The drain oil temperatureis influenced by pressure and speed and isusually higher than the circuit temperatureor the tank temperature. At no point in thesystem, however, may the temperature behigher than 80°C.If the optimum conditions cannot be metdue to the extreme operating parameters orhigh ambient temperature, we alwaysrecommend flushing the motor case inorder to operate within the viscosity limits.Should it be absolutely necessary to use aviscosity beyond the recommendedrange, you should first contactDENISON Calzoni for confirmation.
GENERAL NOTES More detailed information regarding the choice of the fluid can be requested to DENISONCalzoni. When operating with HF pressure fluids or bio-degradable pressure fluids possiblelimitations of the technical data must be taken into consideration, please see information sheetTCS 85, or consult DENISON Calzoni.
OPERATING VISCOSITY RANGE The viscosity, quality and cleanliness of operating fluids are decisive factors in determiningthe reliability, performance and life-time of an hydraulic component. The maximum life-timeand performance are achieved within the recommended viscosity range. For applications thatgo beyond this range, we recommend to contact DENISON Calzoni.
νrec. = recommended operating viscosity 30...50 mm2/s
This viscosity refers to the temperature of the fluid entering the motor, and at the same timeto the temperature inside the motor housing (case temperature). We recommend to select theviscosity of the fluid based on the maximum operating temperature, to remain within therecommended viscosity range. To reach the value of maximum continuous power theoperating viscosity should be within the recommended viscosity range of 30 - 50 cSt.
LIMITS OF VISCOSITY RANGE For limit conditions the following is valid:ν
min.abs.= 10 mm2/s in emergency, short term
νmin.
= 18 mm2/s for continuous operation at reduced performances
νmax.
= 1000 mm2/s short term upon cold start
CHOOSING THE TYPE OF FLUID The operating temperature of the motor is defined as the greater temperature between thatACCORDING TO THE OPERATING of the incoming fluid and that of the fluid inside the motor housing (case temperature).WeTEMPERATURE recommend that you choose the viscosity of the fluid based on the maximum operating
temperature, to remain within the recommended viscosity range (see diagram). Werecommend that the higher viscosity grade must be selected in each case.
FILTRATION The motor life also depends on the fluid filtration. At least it must correspond to one of thefollowing cleanliness. class 9 according to NAS 1638
class 6 according to SAE, ASTM, AIA
class 18/15 according to ISO/DIS 4406
In order to assure a longer life a cleanliness class 8 to NAS 1638 is recommended, achievedwith a filter of β
5 =100. In case the above mentioned classes can not be achieved, please
consult us.CASE DRAIN PRESSURE The lower the speed and the case drain pressure, the longer the life of the shaft seal. The
maximum permissible housing pressure is
pmax
= 5 barIf the case drain pressure is higher than 5 bar it is possible to use a special 15 bar shaft seal(see page 45, Seals, Code"F1").
"FPM" SEALS In case of operating conditions with high oil temperature or high ambient temperature, werecommend to use "FPM" seals (see page 45, Seals, Code "V1"). These "FPM" seals shouldbe used with HFD fluids.

FLUSHING CIRCUIT(MONO-DIRECTIONAL ROTATION)
FLUSHING CIRCUIT(BI-DIRECTIONAL ROTATION)
FLUSHING The motor case must be flushed when the continuous operating performances of the motorare inside the "Continuous operating area with flushing" (see Operating Diagram from page11 to page 25), in order to assure the minimum oil viscosity inside the motor case of 30mm2/s (see page 8 - Fluid Selection). The flushing can be necessary also when the operatingperformances are outside the "Continuous operating area with flushing", but the system isnot able to assure the minimum viscosity conditions requested by the motor as specified atpage 8.
NOTE1: The oil temperature inside the motor case is obtainable by adding 3°C to the motor surfacetemperature (t
A , see figures).
NOTE2: With the standard shaft seal the maximum drain case pressure is 5 bar. For the selection ofthe restrictor, please consult us.

ELECTRONIC DISPLACEMENT REGULATOR “RCE“- MOTOR TYPE MRD - MRDE - MRV - MRVE
RCECIRCUIT FOR VARIABLE DISPLACEMENT MOTOR
DESCRIPTION The circuits of the regulator are powered through a DC/DC converter having 15 V DCoutput, so to obtain a total galvanic separation from the 24 V DC power lines. The inputreference signal to the regulator has been set in the range 2¸10 V DC, as for the output ofthe regulated values (displacement, pressure, speed). Three internal led show the commandcondition (+ or -). The pilot oil is dosed at each pulse by a specific dual metering valve type“VDD”, fitted beneath the solenoid valve. In relation to the parameter that it is wished tokeep under control by acting on the motor displacement, the RCE/I regulator can allow 3different regulation modes.
CONSTANT DISPLACEMENT MODE The hydraulic motor is equipped with an inductive (TEC) displacement transducer poweredby the regulator, which statically reads and saves the current displacement position at eachmotor revolution.Through special built-in valves, the motor keeps the set displacement position constant.Due to an intrinsic feature of radial-piston motors, the tendency under load is to movetoward maximum displacement.Thus the function of the regulator is to restore the original setting with an external voltagereference (range 2¸10 V DC from min. displ. to max displacement).The precision of the actual displacement value is approximately + 2¸3% over the ratedvalue set.For remote reading of the displacement a 2¸10 V DC output signal is provided, almostlinear in the range of the motor displacement variation.To quickly change from one value to another of the set displacement, a special opto-insulated input circuit may be activated in transitory mode with a 24 V DC signal.To enable the regulator only when the motor is running, it is necessary to activate a specialopto-insulated input circuit with a 24 V DC signal simultaneously with the start command;an internal trimmer allows a short enabling delay to be inserted if desired.The regulator is normally set to perform stable adjustments up to a minimum speed of 60r.p.m.For lower speeds, to approximately 6 r.p.m., it is necessary to use an internal multiple-turntrimmer to modify the pause length between the control pulses.The pause length must be greater than the time required by the motor to complete one turn,this is to permit the displacement position read by the transducer at each shaft revolution tobe updated in the memory.

ELECTRONIC DISPLACEMENT REGULATOR “RCE“- MOTOR TYPE MRD - MRDE - MRV - MRVE
CONSTANT WORKINGPRESSURE MODE When the motor is used in systems equipped with hydraulic accumulators and the torque
required by the motor may vary in relation to the process characteristics, the displacement iscontrolled in relation to the working pressure set for the motor, so that the working pressureremains constant as the required torque varies.The constant pressure regulation can be achieved for torque variations within the displacementvariation ratio allowed by the motor.The hydraulic circuit that feed the motor must include a pressure transducer that may bepowered by the regulator itself with a voltage of 15 V DC and a signal output of 0¸10 V DC or4¸20 mA. The hydraulic motor is equipped with built-in valves, to maintain the displacement, aswell as with the displacement transducer if it is wished to read the actual displacement duringtorque changes (by processing the displacement signal together with the pressure and speedsignals, it is possible to determine the torque and absorbed power). The pressure setting isachieved by means of an external signal in the range 0¸10 V DC (2¸ 10 V DC); the 10 V valuemust correspond to the full scale value (10 V or 20 mA) of the pressure transducer. The min.acceptable reference value is 2 V DC. During the startup transitory, the regulator remainsdisabled for an adjustable period of time (internal trimmer).Also in this case the regulator is enable with a 24 V DC input signal.Even with frequent start-stop cycles, the regulator can change the motor displacement to adaptit to the average pressure value saved during the running cycle.The saved pressure signal can be read remotely, again in the range 0¸10 V DC. A third 24 V DCpower output is available on the regulator to simultaneously energize a 2-way solenoid valve ofthe type with a conical diaphragm, which intercepts the pilot oilupstream the 4-way solenoidvalve.
CONSTANT SPEED MODE If multi-stage fixed displacement pumps are used to drive the motor, in certain conditions it isnecessary to drain off the excess delivery in relation to the set motor speed.In order to avoid this dissipation, it is possible to use a variable-displacement motor which wouldabsorb the excess delivery by adjusting its displacement. The regulator in this case accents thespeed signal and compares it to the reference value; when the motor speed exceeds the set value,the regulator increases the displacement until the excess delivery provided by the pump isabsorbed; at the same time, the working pressure is proportionally reduced, to the advantage ofthe life of the components of the system (pump, motor, etc.).This provides a simple speed regulating system without energy dissipation, since the circuitincludes neither flow regulator valves nor drainage valves. The speed signal saved is alsoavailable as output signal for remote reading, again in the field of 0¸10 V DC; this signal may beuseful for detecting the maximum speed reached when the motor running cycle is very short(< 2 sec). Here again, the regulation is enable by activating the special 24 V DC input circuit; thecommand may be delayed by the time the motor needs to accelerate in order to reach the ratedspeed. If it is wished to switch quickly the speed from one value to another, a special input maybe activated with a 24 V DC signal in transitory mode. The precision attainable through thissystem varies: it is approximately ± 2% on the fullscale value with the motor at maximumdisplacement; at minimum displacement the precision is slightly lower.
