負圧制御電磁弁。A constant pressure valve section that controls the negative pressure from a negative pressure source to a constant negative pressure, and a solenoid valve section that dilutes the negative pressure by introducing atmospheric air into the negative pressure passage of the constant negative pressure supplied from the constant pressure valve section. In the negative pressure control solenoid valve, a valve seat is provided with an atmospheric air introduction passage communicating with the negative pressure passage, and a valve body of the solenoid valve that approaches and separates from the valve seat to open and close the valve opening of the atmospheric air introduction passage. In addition, an orifice is provided in the atmosphere introduction passage, and an intermediate negative pressure chamber having a passage cross-sectional area larger than the orifice is formed between the orifice and the valve port of the atmosphere introduction passage. valve.
