ABSTRACT:
A brake pressure booster for a vehicle brake system comprises a vacuum booster which includes two chambers, the low pressure chamber (16) of which is evacuated during actuation in a brake pressure boosting fashion, while a pressure higher than that in the low pressure chamber is adjustable in the high pressure chamber (14) by means of a control valve (28), the higher pressure exceeding the external atmospheric pressure. That is accomplished by a mechanical regulating valve (12) connected upstream of the control valve (28). Upon connection of a pressure source (18) to the high pressure chamber (14), a valve seat controlling access from the pressure source (18) to the valve opens before another valve seat closes that controls the connection between an inlet (24) into the valve and the high pressure chamber (14).
