Claim:
A normally-closed electromagnetic valve comprising: a body member having a receiving space extending therethrough; a fixed core mounted to the body member so as to close one end portion of the receiving space; a valve seat fixed to the other end portion of the receiving space; a moving core opposing to the fixed core and sliding within the receiving space; a resilient member urging the moving core toward the valve seat; a valve element which is mounted on the moving core so as to move forward and backward together therewith, and is capable of abutting against the valve seat; a coil exciting the fixed core so as to produce an attracting force between the fixed core and the moving core; wherein the moving core has a through hole extending therethrough from a fixed core-side thereof to a valve seat-side thereof, the valve element is inserted into the through hole from the valve seat-side and is press-fitted thereto, at least a part of the resilient member is inserted into the through hole of the moving core from the fixed core-side, the resilient member is compressed between a moving core-side end of the fixed core and a fixed core-side end of the valve seat, the moving core has a resilient member receiving portion into which the resilient member is inserted from the fixed-core side, the valve element has a communication portion in an internal space of the body member which communicates the valve-seat side and the fixed core-side of the moving core with each other, and the communication portion of the valve element comprises a passage communicating with a space formed by the valve seat and the moving core.
