  • Patent number: 8622486
    Abstract: The invention is based on a hydraulic unit for regulating the brake pressure in a vehicle brake system. Hydraulic units of such a type are the core component of an anti-lock vehicle brake system, of a drive slip vehicle brake system or of a vehicle brake system which regulates driving stability. The invention proposes a particularly advantageous arrangement of the required recesses in a housing block of a hydraulic unit. On account of the arrangement, the housing block can be reduced in terms of its dimensions, and can be produced with a lower weight and more simply in terms of production. For this purpose, according to the invention, the pressure fluid connection from one of the ports of the master brake cylinder to the suction side of one of the pump elements extends through the valve receptacle of the switching valve.

  • Patent number: 8523295
    Abstract: The invention relates to a hydraulic assembly of a vehicle brake system with traction control. Hydraulic assemblies include a housing block, which is to be fitted with hydraulic components, and an electronic control unit for activating the components. It is known for a hydraulic connection for a pressure sensor to be provided on a housing block and for the signal of the pressure sensor to be taken into consideration for brake pressure regulation in the control unit. The invention proposes an advantageous arrangement of at least one second hydraulic connection for a second pressure sensor on the housing block in combination with blind bores of the hydraulic connections. The blind bores can be positioned in a variable fashion and formed with different lengths during the production of the housing block. In this way, it is possible for the pressure in different hydraulic partial regions of a vehicle brake system to be sensed in an application-specific manner.
