。As the drive shaft rotates, the plunger moves back and forth,
In a plunger pump or motor configured to discharge high-pressure oil from one port through an outlet formed in the valve plate, and to suck tank oil from the other port through an inlet of the valve plate, the valve plate A jet diffusion part is formed at the end on the exit side of the plunger, and the jet diffusion part is composed of an introduction notch and a diffusion notch, and the introduction notch has a bottom inclined toward the plunger hole. On the other hand, in the erosion prevention structure of a plunger pump or motor, the diffusion notch is inclined in the opposite direction to the introduction notch.
