Abstract: 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.

Abstract: 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.

Abstract: A compressor assembly for a compressed air feed of a compressed air supply system includes a compressor having a cylinder and a connecting rod in a connecting rod plane. The at least one connecting rod includes a compressor piston and a connecting rod bearing. The compressor assembly further 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. The drive shaft bearing and the connecting rod bearing are arranged such that the drive shaft bearing is situated at least partially within the connecting rod bearing in a radial direction.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates a compressed air recovery device, a compressed air supply system and a recovery module as well as to a method for operating a compressed air recovery device, to a control module and to a vehicle. A compressed air recovery device (30) comprises a compressed air inlet (1) to which a compressor (2) can be connected. The compressed air inlet (1) is connected to a pressure line (3) to which a system pressure line (5) is connected via a non-return valve (4). A drying unit (11) is arranged in the pressure line (3). A regeneration path (22) which can be connected to the system pressure line (5) depending on the switch position of a vent control valve (23) runs into the pressure line (3) between the drying unit (11) and the non-return valve (4). The supply of compressed air to the compressed air inlet (1) can be controlled by an electrically actuated supply control valve (17).

Abstract: The invention relates to a method for preventing a vehicle, in particular a commercial vehicle, from rolling away, wherein the vehicle is equipped with a compressed air treatment unit (APU) and at least one associated pressure sensor for detecting at least one pressure in a brake circuit, in particular with an electronic compressed air treatment unit (E-APU), and a self-braking system (for example ASR, ESP, FDR, EBS). The invention further relates to a computer program product, which carries out such a method. Furthermore, the invention relates to an electronic compressed air treatment unit (E-APU) and to a self-braking system (ASR, ESP, FDR, EBS).
