Abstract
Eine Zentralverriegelungsanlage hat nebeneinander ein pneumatisches Stellelement (2) zur Betaetigung einer Verriegelungsstange (12) und ein pneumatisches Stellelement (3) zur Betaetigung einer Diebstahlsicherungsstange (13). Die Arbeitskammern (4, 5) beider Stellelemente (2, 3) werden ueber einen gemeinsamen Druckmittelanschluss (7) mit Unterdruck oder Ueberdruck versorgt. Ein Halteelement in Form einer Rastvertiefung (19) und einer federbelasteten Kugel (20) sorgt dafuer, dass bei Ueberdruckbeaufschlagung beider Stellelemente (2, 3) die Diebstahlsicherungsstange (13) so lange festgehalten wird, bis die Verriegelungsstange (12) in Verriegelungsstellung gelangt ist.

DE 3915862 A UPAB: 19930928 The motor vehicle is provided with a centrally controlled locking system for the doors, boot lid, and bonnet. Each lock is actuated by means of two rolling diaphragms (10,11) installed in chambers (4) and (5) respectively which are mounted side by side. The diagram shows the lock mechanism in the locked position. The lock is released either by actuating an outside lever (24) or an inside lever (25) which set the pump (8) operating. This pump draws air from the chamber (5) so that the rolling diaphragm moves upwards and swings the anti-theft lever (17) upwards. The rod (27) attached to the diaphragm (11) opens the valve (9) so that air is drawn from the second chamber (4) and the second diaphragm moves upwards together with the rod (12) to allow the security lever (14) to move upwards. The mechanism is held in this position by a spring-loaded ball catch (20). USE - Central locking for motor vehicles. 1/8
