Abstract
The focus of the present contribution is hydraulic energy recovery by means of hydro-
pneumatic multi-chamber accumulators. A simulation study is presented comparing two
different multi-chamber accumulator concepts for energy recovery in an exemplary load
case involving a forklift mast. The first concept is based on the ��ouble Piston
Accumulator� /1/. It is compared to the so-����� ����� �� �������� ��� ���� �� �
similarities and differences of the two concepts are discussed in the presentation.
KEYWORDS: energy efficiency, hydraulic hybrid, multi-chamber accumulator

Abstract
The focus of the present contribution is hydraulic energy recovery by means of hydro-
pneumatic multi-chamber accumulators. A simulation study is presented comparing two
different multi-chamber accumulator concepts for energy recovery in an exemplary load
case involving a forklift mast. The first concept is based on the “Double Piston
Accumulator” /1/. It is compared to the so-called “Digital Accumulator” /2/. Both
similarities and differences of the two concepts are discussed in the presentation.
