Abstract: The disclosure relates to an actuating system for a vehicle brake, with an actuating arrangement, in particular a brake pedal, at least one (first) piston-cylinder unit, which is connected via a hydraulic line to the vehicle brake (braking circuit) in order to supply the braking circuit with pressure medium and apply pressure to the vehicle brake, and with a drive for the piston-cylinder unit. Pressure medium can be fed to the braking circuit in controlled manner in both piston movement directions, in particular the advance stroke and the return stroke, by means of at least one, in particular stepped, piston of the piston-cylinder unit.

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.

Abstract: The invention relates to a pressure-volume delivery system comprising a piston-cylinder unit with a piston acting on both sides (dual-action reciprocating piston), said piston having at least two different active surfaces in corresponding pressure chambers and the pressure chambers being connected to at least one consumer via hydraulic lines. The delivery system also comprises a drive for the piston-cylinder unit. According to the invention, the pressure chambers and/or hydraulic lines are interconnected by means of at least one or more switching valves connected in parallel and having a large flow cross-section (AV) and via a short hydraulic line or lines with low flow resistance.
