残圧排除型リリーフ弁。 The electromagnetic plunger reciprocates due to the electromagnetic force generated by passing a pulsed intermittent current through the electromagnetic coil and the repulsive force of the spring, and the discharge plunger operates in conjunction with the electromagnetic plunger. In an electromagnetic pump that performs a pumping action using a suction valve and a discharge valve, and is equipped with a shutoff valve mechanism that closes the discharge port side when the action is stopped, a bypass flow path is provided that communicates from the discharge side to the suction side in the pump. A relief valve element, which is seated on a relief valve seat provided in the flow path on the discharge side, is attached to one end of a cylindrical valve holding housing having a valve chamber inside, and a leak valve seat and the relief valve element are attached to the valve chamber. A leak valve element that is pressed by an elastic body and seats in contact with each other with flat surfaces is built in, and the relief valve element and the relief valve element are connected to each other through a leak groove provided between the leak valve seat and the leak valve element. A leakage path is provided that constantly communicates with the discharge side and suction side flow paths of the bypass flow path through through holes penetrating the valve holding case, and the leakage path is further provided with a leakage path that is constantly communicated with the flow path on the discharge side and the suction side of the bypass flow path through through holes that respectively penetrate the valve holding case. 1. A residual pressure elimination type relief valve for an electromagnetic pump, characterized in that the relief valve element is pressed against a relief valve seat.
