Patent ID: 8128180

Claim:
A hydraulic vehicle brake system having a device for regulating the wheel slip, traction, and/or vehicle stability, comprising a hydraulic block having installation spaces for hydraulic components, such as pumps, valves, and/or reservoirs, the hydraulic block being in contact with external devices, embodied as a master cylinder and as wheel brake cylinders, the hydraulic block having pressure-fluid-carrying conduits, which hydraulically connect the components with one another in accordance with a hydraulic circuit on which the vehicle brake system is based, the hydraulic block embodied as: a first conduit connecting a first installation space of a first valve with a second installation space of a second valve and which discharges at an outer face of the hydraulic block; a second conduit discharging into the first conduit; and a closure element being inserted into the first conduit, and which has a first sealing section that closes off the first conduit from the outside in pressure-fluid-tight fashion, and which has a second sealing section diametrically opposite the first sealing section, the second sealing section being located on the far side of a discharge point of the second conduit into the first conduit and blocking communication of the first installation space with the second installation space or blocking communication of the second conduit with the second installation space, wherein the closure element has a center portion, bathed by pressure fluid and located between the first and second sealing sections.
