摘要： A pneumatic central locking mechanism for doors and/or hinged covers of automotive vehicles wherein one pneumatic operating member is provided at the doors or hinged covers to be locked by the central locking operation for locking and unlocking locking devices associated with such doors and covers. A pump, drivable by an electric motor, produces excess pressure and vacuum with a reversing valve being provided for selectively delivering the excess pressure and vacuum to the pneumatic operating members. The reversing valve is operated by a pneumatic operating member which is pneumatically connected in parallel, by way of a throttle, to the operating members associated with the doors and hinged covers. Two double throw switch arrangements are provided with one of the double throw switch arrangements being actuated by the further operating member.
