Abstract: A rotary fluid pressure device is disclosed of the type including a gerotor displacement mechanism (17), a rotary valve member (55), and a valve seating mechanism (75). The valve seating mechanism includes a balancing ring member (77) seated in an annular groove (81) defined by the valve housing (21). Leakage fluid from the gerotor displacement mechanism passes from the central case drain region (83) through the bearings (33 and 35) to an annular chamber (87). The leakage fluid is communicated from the annular chamber (87) to whichever of the ports (75 or 61) is connected to the system reservoir, through a series of fluid passages (131, 133, 135, 137, and 139). The fluid passage (139) communicates with the annular groove (81), and the leakage fluid flows past whichever of the balancing ring seals (143 or 145) is subjected to low pressure fluid, the balancing ring seal thus acting as a check valve. The invention eliminates the complicated and expensive prior art check valve assemblies (103, 105).

Abstract: An assembly of plate members for forming a commutator valve for hydraulic devices of the expanding-contracting pocket type, such as hydraulic motors. The assembly includes a first end plate, a second end plate and a plurality of intermediate plates therebetween. The first end plate includes first and second arrays of fluid passageways for communicating with expanding and contracting fluid pockets, respectively, during operation of the motor. The intermediate plates may be assembled together in either a first or a second alignment depending upon the desired direction of rotation of the hydraulic motor. The intermediate plates are designed such that in the first alignment they direct high pressure fluid from a high pressure port to the first array of passageways and low pressure fluid from the second array of passageways to a low pressure port. The output shaft of the hydraulic motor thus rotates in one direction. In the second alignment the intermediate plates direct high pressure fluid from the high pressure port to the second array of passageways and low pressure fluid from the first array of passageways to the low pressure port. The output shaft of the hydraulic motor thus rotates in the reverse direction. Certain plate members have indicia which identifies the direction in which the output shaft of the motor will rotate.

Abstract: A hydraulic motor of the Gerotor-type which is designed for rotation in both the clockwise and the counterclockwise direction and which includes a pair of relief valves arranged to protect the motor shaft seal, irrespective of the chosen direction of rotation. The Gerotor element also includes a pair of motoring grooves which cooperate with a feed channel formed in the surface of the motor end plate and with a corresponding shadow feed channel on the opposite motor front plate to equalize the forces on the rotor element of the Gerotor and thereby prevent distortion and binding of the rotor element due to thrust forces thereon. Similarly, to prevent excessive forces on the end of the motor shaft, a relief groove is provided between the normal low pressure outlet port and the bearing chamber in the end plate, such that the hydraulic force acting on the end of the shaft tending to urge it in the axial direction is no greater than the product of the cross-sectional area of the shaft and the pressure maintained at the low pressure side of the motor.

Abstract: In an internal gear pump or motor the insert control member between the inner and the outer gear is provided with balancing pockets, which receive fluid under pressure to counter-balance the pressure forces exerted onto the inner and outer gear of the device. Thereby it is obtained, that the radial forces of fluid onto the inner and outer gear are balancing each other by diametrically located oppositional directed fields of force of pressure in fluid. The inner and outer rotors such float freely between radial forces of fluid. Radial rest loads are prevented and the life of the rotors is extended. There may be a single insert or a plurality of inserts and there may be one or a plurality of suction chambers in the device. Additional outer guide means or pressure fields of fluid under pressure may be provided. The loading of the balancing pockets with pressure fluid may be done through respective passages from areas under pressure to said balancing pockets.

Abstract: A balanced fluid pressure device of the type including a housing in which a gerotor gear set and a shaft are supported. The gear set includes an externally toothed star gear and an internally toothed ring gear. An eccentric drive mechanism connects the ring gear with the housing so as to establish orbital movement of the ring gear. The star gear orbits within and rotates relative to the ring gear, and is connected with the shaft by another eccentric drive mechanism so as to establish rotational movement of the shaft. The mass and orbit of each gear are such that centrifugal forces developed upon orbiting thereof are substantially equal and opposite, with the result that inertial loading is substantially balanced.

Abstract: The cooling system includes a cyclically operating cooling-medium compressor driven by the vehicle engine. At low to medium engine speeds, corresponding to speeds from idling to city-driving speeds, the cooling system develops a cooling power sufficient to satisfactorily cool the interior of the passenger compartment. At higher engine speeds, corresponding to highway travel, the cooling power developed by the cooling system is automatically decreased by automatically decreasing the per-cycle volumetric throughput of the cooling-medium compressor. The automatic decrease is effected in automatic response to the reaching of a certain engine rpm or a certain condensation pressure in the condenser of the cooling system. In the illustrated embodiment, the compressor is a sliding-vane compressor, and the per-rotation volumetric throughput thereof is decreased by arresting certain ones of the vanes in the retracted position.

Abstract: A hydraulic gear-type machine has two meshing gears with axis-defining shafts received in respective journals having end faces turned axially toward the respective gears and formed with cutouts opening in opposite directions in line with input and output passages formed in a housing carrying the journals and enclosing the gears. The journals abut flatly at the cutouts along surfaces extending axially to immediately adjacent gears and chordally to cylindrical continuations of the outer surfaces of the journals. Each of the journals on each axial side of each gear is therefore formed with a recess opening toward the inlet passage and with a recess opening toward the outlet passage.
