Abstract: A hydraulic unit for an electronically slip-controllable power brake system of a motor vehicle. A cuboidal housing block is equipped with components for generating a braking pressure and for open- or closed-loop control thereof. On a motor side of the housing block, a motor is fastened to drive a braking pressure generator, while on a reservoir side, a reservoir is provided to supply the vehicle brake system with a pressure medium. The reservoir has at least one protruding fastening peg, which projects into a recess open to the outside on the housing block. Using a retaining pin inserted into a transverse bore of the housing block and passing through this recess, the reservoir is anchored to the housing block. The transverse bore, open on the motor side of the housing block, is in a flat portion in which a pin head of the retaining pin lies without the pin head protruding axially beyond a motor side of the housing block.

Abstract: An electrohydraulic power brake system for a motor vehicle traveling autonomously. An auxiliary brake unit is connected to a service brake unit in such a manner, that in the event of failure of the service brake unit, the vehicle brake system may be operated by the auxiliary brake unit. In order to be able to build up a brake pressure rapidly, using the auxiliary brake unit, in the case of cold and viscous brake fluid, as well, check valves, via which hydraulic pumps of the auxiliary brake unit are connected to a brake fluid reservoir of the service brake unit, are provided in the service brake unit.

Abstract: A hydraulic block of a power brake system, which is designed as a cuboidal housing block. The hydraulic block has a power cylinder bore for receiving a power cylinder, and two chambers, which are arranged above the power cylinder bore and form a brake fluid reservoir. On a side of the power cylinder bore that is opposite to the brake fluid reservoir, a separating cylinder is arranged, which extends perpendicularly to the power cylinder bore and in which a separating piston is arranged, which hydraulically separates a first and a second supply connection to a vehicle dynamics control from one another. The separating cylinder is hydraulically connected to the power cylinder so that pressure of the power cylinder can be applied to a first axial piston side of the separating piston and a brake pressure can be generated via a second axial piston side of the separating piston.

The power cylinder borehole is configured with a larger diameter axially outside the guide section. A brake fluid channel extends through the guide section up to an opening of a brake fluid line.

Abstract: A non-return valve having a valve opening spring is positioned between an unpressurized brake fluid reservoir and a brake master cylinder of a hydraulic vehicle power brake system having an externally-powered brake pressure generator. The non-return valve allows for a flow-through in the direction of the brake master cylinder and blocking against a return flow from the brake master cylinder into the brake fluid reservoir starting at a counterpressure in the brake master cylinder specified by the valve opening spring.
