Rotary piston hydraulic pump - has vanes pivoted about own axis between discharge and suction openings

The pump has a drive shaft (241b) which carries a rotor on which there are blades (435) projecting into an annular cylinder in the housing. The inlet and discharge ports enter the annulus tangentially and the blades force the liquid from one to the other. Each blade (435) is carried on the end of a pin (37) which can rotate in bearings (239) in the rotor and has an inner extension terminating in a disc (284). This disc runs in a guide ring (311) in which it is displaced so as to rotate the pin and with it the blade. Between inlet and discharge ports the blades have a slight clearance in the annulus and are turned between discharge and inlet to give a tight seal.
