  • Closed level control system for a vehicle
    Patent number: 6726189
    Abstract: A closed level control system includes an air dryer (10) which is mounted in a pressurized air line (4). The compressor output (16) can be connected to the pressurized air supply vessel (12) via the pressurized air line (4). Air from the atmosphere can be transferred via an intake valve (30) into the pressurized air supply vessel (12) via the compressor and the air dryer (10). Furthermore, pressurized air can be discharged into the atmosphere from the pressurized air supply vessel (12) via the air dryer (10) and the intake valve (30). There is a flow in the opposite direction through the air dryer than when filling the pressurized air supply vessel (12) from the atmosphere. In this way, an excellent regeneration of the air dryer (10) is ensured.

  • Gear case having three lubricant chambers
    Patent number: 5768954
    Abstract: A gear case for a vehicle which has three casing chambers in which a first wall (11) separates the first (2) and the second (3) casing chambers from one another. The first wall (11) determines an upper lubricant level (22) while a lower lubricant level (21) of the gear casing is set by the volume of lubricant in the first (2) and the third (4) casing chambers.
