摘要： A fluid pump or motor of the sliding vane type comprising a cam ring (13) and a rotor (25) having a plurality of vanes (36) rotatable therewith and slidable relative thereto in slots (35). At least one cheek plate (16, 17) is associated with the body and rotor. Two pressure chambers (39, 40) are formed for each vane (36) and each vane has two surfaces, one in each chamber, both being effective under pressure In the respective chambers to urge the vanes into engagement with the cam. A generally annular internal feed passage (44) is formed entirely within the rotor (25) and communicates with one set (39) of the pressure chambers. A radial passage (42) is provided along at least one side of each vane (36) extending from the tip to the base thereof, so that cyclically changing pressure is supplied to the other set (40) of chambers. An arcuate valving groove (45) is formed in the cheek plate alongside the rotor (25) in a high pressure zone. The annular groove (45) communicates with the radial passage (42), and axial openings (46) in the rotor (25) extend from a side of the rotor (25) to the annular passage (44) and are adapted to register with the arcuate valving groove (45) as the rotor (25) rotates relative to the cheek plate so that high pressure is applied to the one set (39) of chambers.
