制御弁。 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. and a pilot valve hole provided in the valve housing and communicating with the back pressure chamber, and a pilot valve hole movably disposed within the valve housing to open and close the pilot valve hole in response to energization and demagnetization of the solenoid. In the electromagnetic control valve, a pilot valve is provided with a pilot valve body, and a throttle is interposed between the inlet port and the back pressure chamber. At the same time, a rod part that fluidly and movably penetrates the main valve body is provided integrally and coaxially, and a guide part is provided at the inlet port to guide the rod part, and is in constant communication with the back pressure chamber. An electromagnetic control valve characterized in that an opening on the inlet port side of a passage bored in the rod portion and the guide portion cooperate to form a throttle that is closed when the pilot valve element is opened.
