を特徴とする回転斜板形液圧ポンプ。[Claims for Utility Model Registration] In a rotating swash plate type hydraulic pump comprising a swash plate that is integrated with a rotating shaft and rotates, and a cylindrical piston whose end face is slidably pressed against the inclined surface of the swash plate. , an inlet liquid passage extending from the shaft end to the inside of the swash plate is provided at the axial center of the rotating shaft, and a melon-shaped port extending in the circumferential direction of the swash plate is opened to allow the liquid in the cylindrical piston to flow through the swash plate. A centrifugal vane is disposed within the swash plate and is capable of communicating with the passage, and communicates the melon-shaped port with the inlet side liquid passage to form a fan-shaped passage extending radially from the shaft center. A rotating swash plate type hydraulic pump characterized by:
