Abstract:
A vacuum assist pump system includes a vacuum assist pump for assisting to a brake system by vacuum, wherein it includes a suction compensation pump connected with the vacuum assist pump. Advantageously, a vacuum compensation reservoir is arranged between the vacuum assist pump and the suction compensation pump. The vacuum compensation reservoir comprises a vacuity sensor for its internal vacuity and two interfaces. One of the two interfaces communicates to the suction compensation pump, the other communicates to the vacuum assist pump.
