摘要： A pump assembly (10) including a piston (12) connected to a rotating wheel (30) by a pin (32) radially offset from the axis of rotation of the wheel and a cylinder (14) in reciprocating telescoping relationship with the piston (12) and supported by a hollow shaft (26) for rotation in a housing member (24) so that the piston (12) rotates about the axis of a supporting shaft (22) extending transversely to the reciprocating movement while the cylinder (14) rotates about another axis transverse to the reciprocating movement with the distance between the two axes being adjustable to vary the displacement of the pumping chamber (16) between zero when the two axes coincide to a maximum degree when the two axes are spaced the maximum amount. The housing (24) rotatably supporting the hollow shaft (26) of the cylinder (14) includes two fixed fluid ports (50, 52) which alternately communicate with an axially aligned radial port (48) in the hollow shaft (26).

摘要： A variable displacement fluid pump comprises a rotor rotatably disposed within a housing, an eccentric ring movable close to and apart from the rotor to change a first eccentricity between a center of an inner periphery of the eccentric ring and a fixed center of rotation of the rotor so as to vary a displacement of the pump, and a plurality of pumping chambers each having a variable volume which changes sequentially to introduce thereinto fluid from an inlet port and to discharge therefrom fluid to a discharge port as the motor rotates. The rotor is so disposed that the fixed center of rotation of the rotor is spaced apart by a predetermined second eccentricity from a locus of the center of the inner periphery of the eccentric ring towards the discharge port.

摘要： A hydraulic piston and cylinder machine includes a plurality of pistons and cylinders, a ring of ports for alternatively supplying fluid into, and for allowing the fluid to be discharged from each cylinder, and a cam having a plurality of lobes to control the displacement of the pistons in a cylinder block with respect to the progression of the cylinder block along the direction of the cam or vice versa. Each of the pistons traverses each of the cam lobes during a full rotation of the machine to undergo a number of piston strokes equal to the number of lobes. A control valve is adjustable to route working fluid discharged through at least one of the fluid discharge ports of the machine to the exhaust fluid outlet of the machine during each full rotation of the machine via an isolated pressure zone of the machine. In this zone the pressure of fluid is maintained at a level intermediate the supply and exhaust pressures of working fluid to and from the machine, so as to reduce the capacity of the machine to receive and discharge working fluid. The isolated pressure zone is of constant volume and always includes, at any given time, the cylinders associated with at least two pistons of the machine.
