DL Annular Blowout Preventer - Single

In the design of the Cameron DL annular BOP,

closing pressure forces the operating piston and

pusher plate upward to displace the solid

elastomer donut and force the packer to close

inward.

As the packer closes, steel reinforcing inserts

rotate inward to form a continuous support ring

of steel at the top and bottom of the packer. The

inserts remain in contact with each other

whether the packer is open, closed on pipe or

closed on open hole
