UNTERDRUCKVERSORGUNGSSYSTEM IN EINEM KRAFTFAHRZEUG

摘要

In a vacuum supply system for a brake power booster and at least one additional vacuum-consuming unit in a motor vehicle an improved supply of the additional consuming unit is achieved… - in a first solution according to the invention by means of a parallel arrangement of two lines from one vacuum generator to the additional consuming unit, which lines are both provided with flow restrictors and one of which can be shut off by means of a non-return valve with increased return and/or closing force in order to ensure that the brake power booster has priority of supply, and… - in a second solution according to the invention by fitting a valve, switchable as a function of the prevailing vacuum level, into the line leading from the vacuum generator to the ancillary consuming unit, which valve, depending on its control position, causes varying restriction of this line, which is greater when the prevailing vacuum level is greater than a specific absolute pressure value. ……
