ジンの負圧通路制御装置。 A three-way solenoid valve is interposed in the negative pressure passage that transmits the first pressure fluid due to the negative pressure generated in the intake passage to the pressure responsive member, and during a specific operation, a second pressure fluid having different characteristics from the first pressure fluid is transmitted to the pressure responsive member. In the negative pressure passage control device for an engine that operates the three-way solenoid valve so as to transmit information to the pressure responsive member, the second pressure fluid is applied to the pressure responsive member under conditions where the pressures of the two pressure fluids are close to each other other than during the specific operation. A negative pressure passage control device for an engine, characterized in that an operating means is provided for operating the three-way solenoid valve to a state in which the three-way solenoid valve is transmitted to the engine.
