SOLENOID VALVE

摘要

A solenoid valve which has a structure in which a portion for generating an electromagnetic force and a valve portion for controlling a fluid can be separated. This valve improves the versatility of the components and can reduce the production cost. This solenoid valve has a bobbin on which a coil is provided and a housing equipped with an input port, an output port and a discharge port. The bobbin having a plunger assembled thereto and a housing having a ball for switching a flow passage and a valve rod assembled thereto are so disposed as to oppose each other through a plate, and pawls of the case put on the bobbin are caulked to the housing and the plate for integration. An engagement portion is formed on the end face of the bobbin on the housing side and an engagement portion is formed on the end face of the housing on the bobbin side. A bobbin-positioning engagement portion and a housing-positioning engagement portion are formed on the plate, and are engaged with the engagement portions of the bobbin and the housing so as to secure the positional relationship between the bobbin and the housing.
