Claims

[Scope of utility model registration request]

In a hydraulic pump comprising a suction check valve and a relief valve between a variable chamber whose volume is increased or decreased and a suction port, and a discharge check valve between the variable chamber and the discharge port, the suction check valve and the relief valve are provided. , a valve seat member interposed in a suction passage connecting the suction port and the variable chamber, having a valve hole in the center and having an annular first seat portion on the suction port side of the opening; a flange portion having an annular joint surface that is seated on the first seat portion; a flange portion that is loosely fitted into the valve hole of the valve seat member; and a flange portion having a valve hole in the axis; a cylindrical first valve body with a flange having two seat portions; one end of the first valve body is in contact with the flange of the first valve body; a coil spring with a small spacing between strips that urges the first valve body toward the first seat portion; and a coil spring provided on the variable chamber side of the valve seat member and the first valve body so as to be movable toward and away from the second seat portion. a second seat having a joint surface that is seated on the second seat portion;
A hydraulic pump characterized by comprising a valve body.
