Abstract
A hydraulic brake system with slip control for motor vehicles is provided. The system includes a master cylinder with a hydraulic brake booster arranged in front of the master cylinder. There is at least one static brake circuit connected to the master cylinder and a dynamic brake circuit connected to the pressure chamber of the hydraulic booster. Valves are connected in the brake circuits for the control of the wheel cylinder pressures during slip control. A gasket at the master cylinder piston acts as check valve via which pressure medium may be supplied from the dynamic brake circuit into the static brake circuit by pressurization of the pedal-close front face of the master cylinder piston. The pedal-close front face of the master cylinder piston may be alternatively connected to the dynamic brake circuit or to an unpressurized return reservoir by an electromagnetic switch-over valve. A pressure dependent throttle valve provides passage between the booster pressure chamber and the dynamic brake circuit or a throttle between the booster pressure chamber and the dynamic brake circuit. In this way, there will be a reduction of the pressure gradient of the stage of pressure build-up…
