ABSTRACT:
A solenoid valve device which is easy to assemble and is sealed tightly to prevent leakage of the pressure medium. An armature assembly (30) is inserted into the housing cavity (21) of the housing (20), then affixed by a primary caulked portion (A) which has plasticly deformed a portion of the housing (20). The primary caulked portion (A) is then reinforced with a secondary caulked portion (B) which has plasticly deformed another portion of the housing (20) onto a collar (50). At the same time, the bottom face of the valve plate (31) is forced against the bottom of the housing cavity (21), wherein the housing cavity between the atmosphere end and the pressure medium end, and between the pressure medium ducts on either side of the valve mechanism is sealed fluid-tight.
