。 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, which is slidably fitted while being biased by a spring in the valve closing direction and is formed between the back surface of the main valve and the valve housing, and the reservoir is provided with a back pressure chamber facing the back surface of the main valve body. A pilot valve body is slidably fitted into a guide cylinder provided in a valve housing, and a pilot valve hole is provided at the tip of the guide cylinder and communicates with a back pressure chamber to be opened and closed by the pilot valve body. In an electromagnetic control valve in which a pilot valve is interposed and a throttle is interposed between the inlet port and the back pressure chamber, the pilot valve body operated in the valve closing direction until immediately before the pilot valve hole closes, and the inner surface of the guide cylinder. An electromagnetic control valve characterized in that a diper chamber is formed between the pilot valve body and the front face of the pilot valve body, in which the flow of fluid to the reservoir side is restricted.
