The brake system has at least two hydraulic circuits, and a pressure change can be carried out in at least one wheel brake via the pressure supply device(s). A first housing or module, hydraulically connected to the housing, may contain the valve assembly and the at least one piston and pressure chamber of at least one of the pressure supply devices.

Abstract: A brake system includes two brake circuits having brake circuit lines for two vehicle axles and at least one hydraulic wheel brake in each brake circuit. Each wheel brake is connectable to a corresponding brake circuit or brake circuit line via a paired switch valve for pressure build-up and release in the wheel brake using a pressure supply device that can build up pressure in both brake circuits. At least one circuit separating valve blocks or releases a hydraulic connection line connecting the two brake circuits. At least one outlet valve connects an accumulator container to at least one brake circuit to release pressure. A master cylinder having only one working chamber is actuable by a brake pedal. The working chamber is connectable to the brake circuit line of a brake circuit. A switch valve is used to close or release the hydraulic line.

Abstract: A brake system for motor vehicles may have a main brake cylinder with a floating piston arranged therein, which hermetically seals first and second pressure chambers from one another. The first pressure chamber may be hydraulically connected to a first brake circuit, and the second pressure chamber may be hydraulically connected to a second brake circuit. The brake system may further include a pressure means reservoir under atmospheric pressure, wheel brakes, an electrically controllable pressure supply device for pressure build-up and pressure reduction in the wheel brakes, a valve block with a currentless open inlet valve/switching valve for each wheel brake and with at least one outlet valve, wherein each wheel brake can be hydraulically connected via the switching valve associated with it to a pressure chamber of the main brake cylinder.

Abstract: An actuation system, in particular for a vehicle brake, may include an actuating device, such as a brake pedal, at least one first pressure source, e.g., a piston-cylinder unit (master cylinder), which can be actuated in particular by means of the actuating device and a second pressure source, in particular a piston-cylinder unit, with an electro-mechanical drive. The pressure sources may each be connected to at least one brake circuit via a hydraulic line, in order to supply the brake circuit with pressurising medium and to pressurise the vehicle brake. There may further be a valve device for regulating the brake pressure. It is planned that during forward and return stroke at least one brake circuit can be fed controlled pressurising medium by way of the second pressure source.
