Central locking with sequence control - has pneumatically controlled lock and anti-theft lock sequence controlled by control valve

摘要

The central bolt has two adjacent pneumatic controls, one of which (2) activates a locking bolt (20), and the other (3), which activates an anti-theft lock. The pneumatic chambers are commonly connected by a pressure line (9), and are thus pressurised or depressured. A control valve (10), ensures that the anti-theft control chamber is first activated when chambers are pressured. USE/ADVANTAGE - Lock and security arrangement with a simply constructed operation sequence control.
