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.

Each pressure source is connected via at least one hydraulic line to the hydraulically actuatable device for supplying pressurising medium. A valve device may regulate pressure of the hydraulically actuatable device. Pressurising medium can be supplied in a controlled manner in both movement directions of the pressure-generating arrangement. Provision is made for two working chambers of the second pressure source to be connected by a hydraulic line, and a valve device may be arranged in the hydraulic line.

Abstract: An actuating device for an entirely or partially hydraulic vehicle braking system includes a master brake cylinder with a piston and a working chamber hydraulically connectable to a reservoir, a pedal feel simulator, and, via at least one normally open valve, at least one brake circuit. At least one hydraulic wheel brake is assigned to a brake circuit and connected thereto via at least one separate controllable switching valve. A pressure supply unit has a motor-driven piston and a cylinder. At least one valve assembly includes wheel-specific solenoid pressure control valves. At least one electrical control unit controls valves of the valve assembly and the motor of the pressure supply unit. Outlet valves enable discharge of hydraulic medium from wheel brakes or brake circuits into the reservoir. One housing contains the valve assembly and hydraulic component of the pressure supply unit, and a separate housing contains the master brake cylinder.

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.
