摘要： A fluid pressure operated device including a gerotor (17) including an orbiting and rotating star (27). A balancing plate (19) is biased into engagement by means of pressurized fluid in a space (102), with an adjacent end surface (28) of the star (27). Adjacent the balancing plate (19) is a housing member (21) defining a seal chamber (83), in which is disposed a seal assembly (89), including a support member (91) and a seal member (93) disposed radially inward from the support member. The outer periphery (92) of the support member (91) is disposed radially outward of a tangent circle (TC) of the bolts (11), thereby moving the pivot point (PP) of the balancing plate (19) further outward radially. This results in an improved ability of the balancing plate to follow the end surface of the gerotor star, whether the height of the star is more or less than that of the gerotor ring (23). As a result, volumetric efficiency is improved, even while the manufacturing cost of the gerotor gear set (17) may be reduced.

摘要： A fluid pressure motor of the type including a gerotor gear set (15) including a star member (31) which orbits and rotates. The motor includes valving (41) which is disposed forwardly of the gerotor gear set, and an end cap assembly (21;111) disposed rearwardly of the gerotor gear set. The star member (31) defines a central opening (89;127) at the rearward end thereof, which may be defined by a separate insert member (125). Within the end cap assembly (21;111) is a lock piston (75;133) biased by a pair of Belleville washers (85,87;121) toward an engaged position (FIG. 1; FIG. 4) in which a lock portion (79) has its beveled portion (91;135) in engagement with the central opening (89;127) of the star (31), thus preventing any further orbital motion of the star, and serving as a parking lock. The lock piston (75;133) and end cap assembly (21;111) define a pressure chamber (99;119) which may be pressurized by an external signal (95) to move the lock piston to its disengaged position (FIG. 2) in which the beveled portion (91;135) is out of engagement with the central opening (89;127), and the star member (31) is permitted to orbit and rotate in the normal manner.

摘要： A gerotor motor of the valve-in-star type in which the star (27) is disposed adjacent a stationary valve plate (15). The stationary valve plate (15) defines a plurality N+1 of stationary ports (65) in communication with the inlet port (55). The gerotor star (27) defines a plurality N of fluid ports (51) each including a radially inner portion (53). The inner portions (53) and the stationary port (65) are in commutating fluid communication as the star (27) orbits and rotates, in accordance with an important aspect of the invention. As a result, the star member (27) is exposed to a smaller area of pressurized fluid at the stationary valve plate (15), thus making it possible to achieve more consistent overbalance of the star, for either direction of rotation. This results in substantially improved overall efficiency of the motor.

摘要： A gerotor motor of the valve-in-star type in which the star (27) is disposed adjacent a stationary valve plate (15). The stationary valve plate (15) defines a plurality N+1 of valve passages (69), extending through the valve plate. On the surface (73) of the valve plate (15) adjacent the endcap member (14), the valve plate defines a plurality of pressure relieving recesses (79), each one being disposed between a pair of adjacent valve passages (69). Each of the recesses (79) is in fluid communication with an O-ring groove (81), which is at low pressure. Thus, any leakage from a high pressure passage (69) to an adjacent low pressure passage (69) is received within the intervening relieving recess (79), substantially eliminating any separating forces between the endcap member (14) and the stationary valve plate (15) This results in substantially improved volumetric efficiency of the motor at higher pressure differentials.
