とするロータリーシリンダ式プランジヤポンプ。 A plunger that is slidably inserted into each of the cylinders of the rotor and comes into contact with a cam member disposed in the housing by rotationally driving a rotor that has a plurality of cylinders and is assembled in the housing. In a rotary cylinder type plunger pump that operates the pump by reciprocating the rotor, an annular groove is provided on the outer periphery of the rotor that communicates with each suction passage leading to each cylinder, and a groove of the rotor is provided corresponding to the annular groove. A rotary cylinder type plunger pump characterized in that an annular pump vane that sucks working fluid from the outer periphery toward the annular groove is integrally attached to the outer periphery of the rotor.
