Abstract: A pneumatic drive unit is provided for partially opening a vehicle body part such as a trunk lid. The pneumatic drive unit includes a working chamber which in use applies pressure to move a control member which engages a contact surface of the vehicle body part. A vent channel is provided which selectively connects the working chamber with the atmosphere as a function of the position of a movable closing element of the drive unit element and contact of the control member with the vehicle body part such that when the body part is closed after a partial opening, the drive unit is ready for another control operation.

Abstract: Apparatus for controlling and adjusting an arbitrary number of adjustment units for a motor vehicle includes an electro-pneumatic bus to which are connected in arbitrary sequence, both electrically and pneumatically, all the pertinent adjusting units. The electro-pneumatic bus is composed of at least one pneumatic adjustment pressure line and of at least one electric control signal line which may contain several conductors. While reference data from a central control electronics are applied through the electric control signal line of the electro-pneumatic bus, the individual adjusting units are connected through associated valves in the pneumatic system to the pneumatic adjustment pressure line of the electro-pneumatic bus. The adjusting units preferably are designed to be modular control loops. As a result the pneumatically driven adjusting members units not only two positions, but also they may be set and controlled in quasi-analogue manner.

Abstract: In a vacuum distributor box with a suction connection and several vacuum connections, all the vacuum connections are equipped with non-return valves open only when vacuum lines are inserted, both the seals of the box housing itself and the those of the vacuum lines relative to the box housing and the valve sealing seats of the non-return valves being incorporated in a diaphragm seal clamped on all sides between two housing parts.

Abstract: A preassemblable cylinder lock/actuator subassembly of a central locking system is designed so that, at the same time as the actuator is necessarily fastened to a lock carrier in the correct position, the actuating member of the actuator is coupled in a functionally reliable way to a lock operating lever.

Abstract: A compact electric adjusting drive for locking systems, fan flaps or the like in motor vehicles includes a fluidic force transmission system between the electric motor and the adjusting element movable to and fro between two end positions.

Abstract: A valve arrangement with a main shifting valve and a pilot control valve in which the main shifting valve controls the connection between an inlet line and an outlet line. Depending on the position of the pilot control valve, a control pressure space is connected with the inlet line and is therewith acted upon with the inlet pressure, respectively, is relieved of the pressure by a connection with an essentially pressureless return line in order to close, respectively, open the main shifting valve. As the inlet, outlet and return lines terminate on the same bottom side of the socket, the valve arrangement can be arranged in a particularly simple manner on a line plate of a hydraulic, respectively, pneumatic shifting arrangement.

Abstract: A pneumatic central locking system for doors and/or lids in motor vehicles, with a pneumatic operating or locking element being provided for each lock mechanism of the doors and/or lids so as to enable the same to be locked and unlocked. An electrically drivable air pump is connectible with the locking elements by a line system and a selector valve is disposed at an outlet side of the air pump. The selector valve acts upon the line system and/or the locking elements in a desirable manner by means of an additional pneumatic operating or switching element connected fluidically in parallel at the locking elements. A response pressure of the switch element is higher than that of the locking elements. At least one lock mechanism contains a key operable first selector switch, with a second selector switch which may be operated by the switching element.
