ROTARY FLUID PRESSURE DEVICE AND IMPROVED PARKING LOCK ASSEMBLY THEREFOR

A rotary fluid pressure device (11) includes an end cap (23) which is disposed rearwardly of, and adjacent, the fluid displacement mechanism (21). The end cap defines a piston cavity (103) in which is disposed a lock piston (105), which is moveable between a first position and a second position, in...

Beschreibung
Zusammenfassung:	A rotary fluid pressure device (11) includes an end cap (23) which is disposed rearwardly of, and adjacent, the fluid displacement mechanism (21). The end cap defines a piston cavity (103) in which is disposed a lock piston (105), which is moveable between a first position and a second position, in which the forward portion (107) of the lock piston extends within a central opening (121) of a rotor member (49) to prevent movement. A release piston (137) is disposed in a central opening (125) of one of the housing member (13) and stationary valve member (63). A brake pin (141) is disposed in a bore (139) of a drive shaft (57), with a first axial end of the brake pin being operably associated with release piston and a second axial end being operably associated with the lock piston.
