Abstract

In a hydraulic motor vehicle brake system with slip control comprising a pressure accumulator (13), a hydraulic pump (23), a non-return valve (2) and a brake power booster (17). The pressure outlet of the pump (23) is connected with the pressure accumulator and with an inlet of the brake power booster (17) via the non-return valve (2). The outlet side of the non-return valve (2) is connected with the inlet of the brake power booster (17) via the pressure accumulator (13) in order to reduce noises caused by pressure pulsations in the fluid flow of the pump (23).
