    Abstract: Multiple speed ratio gerotor motor having first (13) and second (19) gerotor gear sets as displacement mechanisms, and a commutating valve member (43). In one embodiment a selector valve section (15) is disposed between the gerotor gear sets. In low speed mode, fluid flows from the commutating valve member through first volume chambers (39), the selector valve section, and second volume chambers (66). In high speed mode, flow out of first volume chambers is blocked by the selector valve section, and fluid in second volume chambers flows through the selector valve section to case drain region (106). In another embodiment, the selector valve section is disposed between commutating valve member and first gerotor gear set, and can permit, or block, fluid communication to either gerotor gear set separately. In either embodiment, the relative speed ratios are determined by the relative axial lengths of the gerotor gear sets, thus providing great flexibility in choice of speed ratios.

    Abstract: A brake assembly of the type in which there are provided brake discs (87,89) which are pressed into frictional engagement by a lock piston (65). The lock piston is of the type applied by a set of Belleville washers (73) and released by fluid pressure in a chamber (113). The invention provides a disengagement mechanism (95) associated with the lock piston (65) and including a manually operable handle (107) disposed external to a housing (21) enclosing the brake assembly. The handle is moveable between a normal position (FIG. 2) and a disengagement position (FIG. 4) in which the lock piston is moved toward at least a partially retracted position, in opposition to the force of the Belleville washers. When pressurized fluid is again communicated to the chamber (113), the lock piston is biased to its fully retracted position, and the handle (107) of the disengagement mechanism (95) returns to its normal position (FIG. 2), ready for the next time the operator wants to manually disengage the brakes.
