Abstract
A rotary fluid pressure device is disclosed of the type including a gerotor displacement mechanism (17). The gerotor includes a ring member (21) and a star member (23) eccentrically disposed within the ring member, and having relative orbital and rotational movement therein. The device includes a spool valve member (51) disposed immediately adjacent the gerotor and adapted to be rotated at the speed of rotation of the star member. The device further includes an output shaft (29). Orbital and rotational movement of the star member is transmitted to the output shaft by means of an elongated, hollow, universal shaft (69). A valve drive shaft (79) is located at least partially within, and extending axially through the hollow universal shaft. In one embodiment of the invention, the valve drive shaft includes a valve end (85) in engagement with the spool valve, and a shaft end (81) in engagement with the output shaft, to transmit rotation of the output shaft into rotation of the spool valve (51).
