Abstract: A control device for controlling a speed of a hydraulic motor includes a housing defining a first void. A speed valve is disposed within the first void and is moveable between a first speed valve position and a second speed valve position. The first void includes a speed valve pressure chamber disposed at one end of the speed valve. A speed valve spring is disposed at another end of the speed valve. The housing further defines a speed change port and a speed change passage interconnecting the speed change port and the speed change pressure chamber for directing a pressurized fluid directly into the speed valve pressure chamber to exert a pressure force on the speed valve and bias against the speed valve spring to move the speed valve between the first speed valve position and the second speed valve position.

Abstract: 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.
