A compressed-air supply installation for operating a pneumatic installation includes a compressed-air feed, a compressed-air connection to the pneumatic installation, and a ventilation connection to a surrounding environment. The compressed-air supply installation further includes a pneumatic main line between the compressed-air feed and the compressed-air connection, the pneumatic main line having an air dryer, a ventilation line between the compressed-air feed and the ventilation connection, and a valve arrangement having a control valve configured to control a ventilation valve. The control valve is connected by a control valve connection in a pneumatic control line that is connected to a pressure control connection of the ventilation valve, the ventilation valve is connected by a ventilation valve connection in the ventilation line, and the control valve is assigned a control valve ventilation connection that is configured to be switchably connected to the ventilation connection or to the surrounding environment.

A compressor assembly includes a compressor having a cylinder and a connecting rod in a connecting rod plane. The connecting rod includes a compressor piston and a connecting rod bearing. The compressor assembly includes a drive having an axis of rotation, a drive shaft, and a housing. The drive shaft is mounted in a drive shaft bearing and has a connecting rod side end and a connecting rod remote end. The drive shaft has a connecting-rod receiving portion which is arranged eccentrically to the axis of rotation of the drive at the connecting rod side end.

A device housing, especially for accommodating an electronic unit or a mechatronic unit, has parts which are sealed against one another in assembled condition via an encircling, stationary seal. At least one pressure-relief device is integrated into the seal for admission of air into the housing. The seal is formed at least in part as a lip that opens under overpressure conditions inside the housing. To allow any water that has penetrated to flow away, the housing is mounted vertically, with the pressure-relief device disposed at the bottom.

For a vehicle equipped with a self-braking system (for example, ASR, ESP, FDR, EBS), a service brake, a parking brake, and at least one associated pressure sensor for detecting at least one pressure in the vehicle brake circuit, the brake circuit comprising a compressed-air circuit, a process to prevent the vehicle from rolling away includes determining whether a pressure in the compressed-air circuit from which the parking brake is fed is below a release threshold, and operating the service brake if the pressure in the compressed-air circuit is below the release threshold.
