プ。 A cylinder block that rotates together with the drive shaft has a plurality of cylinder bores that accommodate pistons that are reciprocated by the action of a conversion mechanism that converts the rotational motion of the drive shaft into linear motion, and the pistons slide against the end surface of the cylinder block. A circular arc-shaped suction port and a discharge port are formed on a valve plate that is fixedly arranged in a predetermined position in a possible state, and a recess that communicates with the discharge port is formed on the sliding surface of the valve plate with the cylinder block. Axial piston pump formed near bottom dead center.
