The tip of a piston rod that reciprocates in a cylinder communicating between a suction port and a discharge port is provided with a flange-shaped valve seat and a valve stopper spaced apart from the valve seat. In a forced valve hole piston pump, a valve body having a piston backing that slides in the cylinder is movably fitted between the valve stopper and the valve seat, which is a gun seat in the valve seat. The gun seat surface and the valve seat form a tapered surface that becomes smaller in diameter toward the valve seat side, and when the valve body is closed, the tapered surface and the valve seat form a space with a wedge-shaped cross section, and water flows into this space. By some of the pumped fluid? A forced valve hole piston pump characterized by having a cushioning effect.
