Abstract: An apparatus for balancing and supporting various loads exerted on the pump cylinder block and associated bevel gear in a radial piston type hydraulic transmission for assuring concentric rotation about the pintle during operation. A hydraulic pressure pad, acting as a hydraulic piston, is located on the outer surface of the pintle at least partially underneath the pump cylinder block hub portion for counteracting the loads exerted against the pump cylinder block and associated bevel gear. A groove circumferentially disposed in the outer surface of the pintle supplies oil to the pressure pad from a bore disposed in the groove and in communication with the high pressure passage of the pintle. The pressure pad is preferably disposed 90.degree. from the input shaft and associated input bevel gear. Additional grooving on the outside circumferential surface of the pintle provides lubrication between the rotating cylinder blocks of the pump and motor, and the pintle.

Abstract: A slipper guide for use in radial piston type hydraulic pumps and motors, especially those utilized in hydrostatic transmissions. The slipper guide provides an annular path for the slippers, guiding and maintaining the slippers engaged with the inner circumferential surface of the track ring as the slippers are rotated within the track ring by the cylinder. The slipper guide consists of two plates axially attached to the track ring and fixed relative thereto. Each plate includes an annular, axially inwardly extending projection forming an annular surface upon which an under surface of an outer portion of the slippers rests. The annular projection positions and maintains the top surface of the slippers against the inner circumferential surface of the track ring.

Abstract: A hydrostatic transmission is provided of the type including a pump (15), a motor (17), and a pintle assembly (35) defining high (61) and low (63) pressure fluid conduits. In communication with the conduits, the pintle assembly includes a pair of acceleration valves (85, 89), each of which comprises a differential area piston. Adjacent each acceleration valve is a pilot valve means (95) disposed in a pilot bore (105) and including a valve member (115) operable, in response to system pressure in excess of the pressure relief setting of a spring (117) to relieve fluid pressure in a chamber (101), such that the acceleration valve (85) is biased toward an open position (FIG. 5) relieving fluid pressure spikes from the high pressure conduit (61) to the low pressure conduit (63).

Abstract: A variable displacement fluid transducer including a plurality of radial pistons arranged in pairs on a rotating piston barrel. Cam tracks circumscribe the pistons and convert the reciprocation of said pistons into rotary motion of a shaft means, or viceversa. Piston chambers provided in the barrel couple the pairs of pistons, and the cam tracks are adjustable to vary the displacement of the transducer by changing the relative reciprocating movement of the pistons comprising each pair.
