Abstract:
An electromagnetic valve to be fixed to a base housing for controlling fluid flow therein, comprising:a solenoid assembly having at least a solenoid and a housing which are integrated into one body, the solenoid having a bobbin whose inside is provided with a solenoid cylindrical hollow and a coil wound around an outer circumference of the bobbin, and the housing being made of magnetic material and surrounding an outer circumference of the solenoid; and a valve body assembly having at least a cylindrical valve case member and a cylindrical valve body member which are integrated into one body, the valve case member having a stator and a valve case, being inserted into the solenoid cylindrical hollow so that the stator is positioned in a vicinity of the coil and being provided in side with a valve case cylindrical hollow extending from the valve case to the stator, and the valve body member having an armature and a valve body and being slidably housed to move reciprocatingly in the valve case cylindrical hollow so that, when the coil is energized so as to generate magnetic flux passing through the stator and the armature, the armature together with the valve body is attracted toward the stator for controlling the fluid flow, wherein an axial end of the housing is fixed partly to an outer circumference of the valve case member to prevent the valve body assembly from dropping out of the solenoid assembly.
