ABSTRACT:
A fluid pressure device of the type including a housing in which a gerotor gear set is supported. The gear set includes an externally toothed star gear rotating within an internally toothed ring gear. The housing and ring gear each define complementary but eccentrically oriented races between which balls are contained so as to establish orbital movement of the ring gear. The housing and ring gear define passages communicating through the eccentric drive to supply and exhaust fluid to and from chambers defined between the star and ring gears.
