ABSTRACT:
A vacuum supply system for a brake power assist unit of a motor vehicle with at least one additional vacuum consuming device is achieved by the installation of a valve, which can be switched as a function of existing vacuum level in a pipe leading from the vacuum generating device to the at least one additional consuming device. Switching of the valve causes a throttling of this pipe to be more extensive when the existing vacuum level is above a certain absolute pressure value.
