Abstract: A vehicle pressure medium device in which a pressure medium flows, has a multilayer design which has at least two mutually contacting layers. A groove-shaped recess is arranged between a first chamber into which a first flow opening opens and a second chamber into which a second flow opening opens when viewed on a plane parallel to the layers. The groove-shaped recess has at least one opening for a fluidic connection between the first chamber and the second chamber on a plane parallel to the layers. A group of molded seals is provided for mounting between the two layers. A fluidic connection is either produced between the first chamber and the second chamber or not depending on the molded seals which are mounted between the two layers and each of which is selected from the group of molded seals.

Abstract: An electric parking brake, in particular for a commercial vehicle, has at least two compressed-air outputs, an electrically controllable valve arrangement for controlling a distribution of compressed air to the compressed-air outputs and including a bistable valve, and a compressed-air input which can be connected to a compressed-air supply for supplying compressed air from a compressor and/or from a compressed-air reservoir to the valve arrangement and to the compressed-air outputs.
