弁。 The valve housing in which an inlet port and an outlet port are provided has a main valve body that can switch communication and isolation between both ports, and a main valve body that faces the inlet port in order to apply fluid pressure in the inlet port in the valve opening direction. A back pressure chamber that is slidably fitted while being spring-biased in the valve-closing direction, and is formed with the back side of the main valve body facing in order to exert fluid pressure that biases the main valve body in the valve-closing direction. A pilot valve hole provided in the valve housing and a pilot valve body movably disposed within the valve housing to open and close the pilot valve hole in response to energization and demagnetization of the solenoid are provided between the valve housing and the reservoir. In an electromagnetic control valve in which a pilot valve is interposed and a throttle connecting an inlet port and a back pressure chamber is bored in the main valve body, the throttle is located at a position offset from the axial extension of the pilot valve hole. An electromagnetic control valve characterized by being bored in the main valve body.
