Abstract: An operating device for a vehicle brake system may include a control device and a piston-cylinder unit, at least one chamber of which may be connected to at least one wheel brake via at least one hydraulic line and a valve device that has at least normally open inlet valves or switching valves. The device may further include a pressure source that may be controlled to supply pressure medium to the at least one hydraulic line or to the at least one wheel brake. The control device may control pressure build-up via volume control and/or time control, using inlet valves. The interior or armature chamber of an inlet valve may be connected to a corresponding brake circuit via a hydraulic line, and a valve seat outlet may be connected to a corresponding wheel brake via a hydraulic line.

Abstract: A brake system may include a first pressure supply unit having an electromotive drive and arranged to supply pressure medium to first and second brake circuits; a motor-pump unit to supply pressure medium to at least one of the brake circuits; a second pressure supply unit, connected to the motor-pump unit via first and second hydraulic lines and arranged to supply pressure medium to at least one of the brake circuits; and a valve unit. The second pressure supply unit may be connected via a third hydraulic line to at least one of the brake circuits. The valve unit may include at least one feed valve via which the third hydraulic line may be at least partially reversibly shut off. An isolating valve may be disposed in at least one of the hydraulic lines to at least partially reversibly shut off the at least one hydraulic line.

Abstract: A vehicle brake system may include: two hydraulic brake circuits, each having at least one hydraulically operating wheel brake; first and second pressure supply devices; at least one valve assembly for adjusting the brake pressure for each wheel individually and/or for separating/connecting the wheel brakes from/to at least one of the pressure supply devices; at least one electronic control and regulating unit; and a hydraulic connection line connecting the two brake circuits. Each wheel brake is paired with a dedicated switch valve, and each brake circuit has a hydraulic main line via which the switch valves may be connected to the pressure supply devices. The connection line has two connection switch valves connected in series and open when unenergized via pressure present in the respective hydraulic main line and/or an inner section of a connection line connecting two connections of the connection switch valves directly together.

Abstract: A braking system for a vehicle may include a hydraulic brake pedal system having a master cylinder having at least one pressure chamber, from which a hydraulic output is coupled to at least one brake circuit via an infeed switch valve. The master cylinder is coupled to a reservoir via at least one opening via a hydraulic connection. A failure of a pressure chamber seal of the at least one pressure chamber of the master cylinder is safeguarded by at least one redundancy, and the failure of the pressure chamber seal or the redundancy of the pressure chamber seal of the at least one pressure chamber of the master cylinder can be diagnosed.

Abstract: A helical gearing for driving an adjusting element, which may be an actuator or a piston of a piston-cylinder unit, is driven by an electric motor. The adjusting element may be moved along an axis. The drive apparatus has a rotor, or a translator rotatably mounted in a housing by a bearing and fixedly connected to the input of or formed integrally with the helical gearing. The output of the helical gearing is connected to or formed integrally with the adjusting element. An anti-twist means may prevent the adjusting element from twisting in the circumferential direction about the axis. The helical gearing and/or at least part of the adjusting element is/are formed to be transversely elastic to the axis of rotation, at least in one region.
