Abstract

PURPOSE: To simplify piping, by controlling output fluid pressure by unifying two negative pressure control valves and by each responding to the negative pressure of two negative pressure signal ports.
CONSTITUTION: A casing 1 of a negative pressure control valve consists of a 1st body 2 with a 1st signal port S1, a 2nd body 3 with a 2nd signal port S2, and a 3rd body 4 with an input port X communicated with atmospheric pressure and a port Z communicated with an exhaust gas recirculation control valve. When negative pressure working on 1st and 2nd both signal ports S1, S2 is weaker than a right srping 8, the input port X and the output port Z do not conduct; when negative pressure signals surpassing the spring 8 are applied to both signal ports S1, S2, the input port X and the output port Z are communicated. When the negative pressure of both signals slowly increases and exceeds the force of a spring 20, a valve 18 is closed, a chamber 16 is interrupted from a chamber 25 and both ports X, Z do not conducted.
