Abstract: A brake system may include: two hydraulic brake circuits, each having at least one wheel brake; a first pressure supply device for pressure build-up and release in at least one brake circuit via forward and return travel of a piston; a second pressure supply device with a continuous delivery, electromotively-driven piston pump, gear pump, or eccentric piston pump; at least one valve assembly with valves for adjusting pressure for each wheel brake and/or for connecting/disconnecting the wheel brakes and at least one of the pressure supply devices; at least one electronic control unit; a connection line connecting the two brake circuits; and at least one outlet valve for pressure release. The wheel brakes are paired with dedicated switch valves. Each brake circuit has a hydraulic main line to connect the switch valves to the first and second pressure supply devices, which provide different maximum pressures and/or delivery volumes.

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.
