A pressure-medium unit includes a housing, which is produced by injection molding and composed of plastic, in the housing wall of which housing at least one connection bush having a passage opening is fastened, through which pressure medium is fed into and/or led out of the interior of the housing. In the injection molding process of the housing, the connection bush, with the exception of the passage opening, is at least partially injection-molded into the housing wall.

A service brake device for vehicles is provided which permits rapid venting of a service brake pressure chamber. The service brake device includes at least one pneumatic service brake device with at least one piston and/or a diaphragm. The piston and/or diaphragm delimits the service brake pressure chamber on one side which can be supplied with compressed air from a brake line for applying the service brake and can be purged of compressed air for releasing the service brake, delimits a spring chamber on the other side which receives a spring that prestresses the piston and/or the diaphragm in the release position of the service brake. The pressure chamber includes a pressure connection communicating with the brake line. A quick air release valve between the brake line and the pressure chamber is arranged to connect the brake line to the pressure chamber when the pressure in the brake chamber is greater than in the pressure chamber, and to connect the pressure chamber to the spring chamber when the pressure in the pressure chamber is greater than the brake line pressure.
