Abstract: A brake system for a vehicle has at least two hydraulic brake circuits, each with at least one hydraulically acting wheel brake, and a switching valve on each hydraulically acting wheel brake, which switching valve connects in each case one hydraulically acting wheel brake to one of the two brake circuits. The brake system also has a central outlet switching valve which brings about a switchable hydraulic connection between at least one of the brake circuits and a reservoir vessel, wherein the reduction in pressure in the at least one hydraulically acting wheel brake is effected by opening the central outlet switching valve and the associated switching valve.

Abstract: A piston-cylinder unit includes a piston delimiting at least one working chamber, in which a first seal for sealing at least one first working chamber is arranged either between the piston and cylinder or between a plunger connected to the piston and the cylinder. A second seal is arranged between the first seal and the first working chamber, and the piston-cylinder unit further includes a first channel arranged in the wall of the cylinder or in the piston, which joins the first seal and the second seal in the inner chamber of the cylinder. The first channel and/or a hydraulic line connected thereto may have a throttle device and/or a valve device. An electronic control and regulating device may have a diagnosis or monitoring function for a possible defect or failure of a seal. Multiple hydraulic devices may have such piston-cylinder units and respective control and such regulating devices.

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.
