Abstract

PURPOSE:To accumulate the negative pressure which is larger than the sucking negative pressure of an engine into a negative pressure chamber, by providing a vacuum pump in a negative pressure circuit which links the suction system of the engine and to negative pressure chamber in the negative type booster system though a check valve. CONSTITUTION:A negative pressure taking out hole 8 is provided on the down stream with respect to a throttle valve 7 in the suction system 4 of the engine E. Said hole 8 and the negative pressure chamber 3 in a booster shell 1 are connected through a negative pressure path 9. In this place, a side path 12 which bypasses the check valve 10 is connected to the negative pressure path 9. The vacuum pump 13 is provided in said side path 12.
