Abstract: A slip-controllable vehicle brake system includes a brake circuit to which a master brake cylinder is connected to a wheel brake. The connection between the brake circuit and the master brake cylinder is controlled by a changeover valve. To supply the wheel brake with pressure medium, the brake circuit has a pressure generator that is externally driven and interacts with a pressure build-up valve of the wheel brake. The brake system includes a pressure pulsation damping device with a pulsation damper and a resistor which forms a flow cross-section. The pressure build-up valve and/or the changeover valve is continuously adjustable and steplessly switched from an open position into a blocked position. The flow cross-section of the resistor is actualized by an electronic triggering of the pressure build-up valve or the changeover valve such that it is variably adjusted to changing environmental or operating conditions.

Abstract: A hydraulic vehicle braking system having a primary braking cylinder to which the vehicle braking system is connected via a separating valve is disclosed. The vehicle breaking system includes slip control. A pedal path simulator is a spring-loaded hydraulic accumulator, which can be connected to the primary brake cylinder via a differential pressure controlled simulator valve. The simulator valve opens when a braking pressure in the vehicle braking system is greater than a primary braking cylinder pressure; otherwise, the simulator valve is closed. If the separating valve is closed during slip control, for example, the primary braking cylinder forces braking fluid through the opened simulator valve into the hydraulic accumulator upon actuation so that a normal pedal characteristic occurs at least approximately when the separating valve is closed.
