发明名称 ELECTROMAGNETIC VALVE, FLUID PUMP HAVING THE VALVE, AND FLUID INJECTOR HAVING THE VALVE
摘要 An electromagnetic valve includes a valve body having a passage and a valve seat, a valve member engaging/disengaging from the seat to stop/allow a fluid flow through the passage, an urging member urging the valve member, a movable part reciprocating in axial direction with valve member, a connector made of magnetic material and accommodating movable part to allow its reciprocation, a stator made of magnetic material and constituting a magnetic circuit with the movable part and connector to attract the movable part, a coil generating magnetism attracting movable part to stator when energized, a terminal connected to coil for supplying power, and a resin-formed member including an accommodating member embedding the coil and terminal, and a nonmagnetic member made of nonmagnetic material and located radially inward of coil and between the connector and stator for preventing a short circuit. The accommodating member and nonmagnetic member are formed integrally from resin.
