<p>The objective of the present invention is to enable an improvement with respect to the destabilization of flow volume control when an elastic member makes partial contact with a valve seat. This electromagnetic valve is equipped with a plunger (17) inserted into a cylindrical plunger-housing body (3) so as to be capable of reciprocal motion. A housing part (30) is formed on the valve chamber (8) side of the plunger (17). An elastic member (31) that faces the valve seat (10), and a hard ball (32) arranged on the side opposite the valve seat (10) with the elastic member (31) therebetween, are provided in the housing part (30), and a retaining member (33) that retains the outer circumferential edge of the elastic member (31) is provided on the plunger (17). One point near the center of the elastic member (31) is pressed by the hard ball (32), and the elastic member uniformly contacts the valve seat (10). Thus, partial contact of the elastic member (31) with respect to the valve seat (10) is eliminated.</p> |
