摘要

The pneumatic mechanism to operate the passenger door (101), of a security vehicle, has a lever linkage to open and close the door. The system has two end switches, one to open and the other to close the door, so that the driver can operate the door from the driving position. The door movements can only be operated when the motor is switched off, while the driver has a switch which can close the door even while the motor is running.
