In a pneumatic system with a working element which works by means of a diaphragm and actuates an auxiliary device in a motor vehicle, in particular with a locking means, which auxiliary device has at least one chamber and is supplied with positive pressure and/or vacuum via at least one hose line, and with a control valve which can be actuated manually or by remote control, according to the invention the hose line is partly designed as a safety hose which has a pneumatic valve which interrupts the connection, transmitting the positive pressure and/or vacuum, between the working element and the safety hose if the safety hose is severed. Through this special design of the hose line, the disadvantages of known pneumatic systems, in particular the inadequate protection against theft, are avoided in a simple and inexpensive manner. |
