A variable displacement vane pump includes a rotor (10) rotatably mounted in a casing (32). The casing (32) has a pair of relatively rotatable complementary cams (18,20). Each cam (18,20) has a surface shaped to provide an annular curvilinear track. The pump also has a first (14) and second (16) plurality of vanes slidably mounted upon the rotor (10). Each of the vanes (14,16) is sized and positioned to engage a corresponding cam (18,20). These vanes (14,16) are constrained in a radial direction by the cams (18,20) as the rotor (10) rotates. The vanes of...
