Abstract
PURPOSE:To enable integration of a regulator valve and a solenoid valve in a compact size without marring the both function by maintaining a negative pressure chamber and a pressure regulating chamber at the negative pressure within its setting range. CONSTITUTION:Negative pressure at any level within its setting range can be a negative pressure with its proper assigned signal in such a way that the inside of a negative pressure chamber R1 is always maintained at the negative pressure within its setting range through repeated operation of a valve member 13 drive in response to fluctuation of air inlet negative presure in an intake manifold, said negative pressure within its setting range is applied into a pressure regulating chamber R3, and the valve body 23b of a flapper valve body 23 repeats its action in the pressure regulating chamber R3. In consequence, in a negative pressure valve, though a regulator valve 10 and a solenoid valve 20 are integated, it can be made compact without marring the function of the both valves.
