ABSTRACT:
A vacuum actuated door latching assembly for use in combination with a door of a delivery vehicle. The latch assembly moves between locked and unlocked positions and includes a pneumatic actuator that drives the latch assembly between the locked and unlocked positions. Extending from the pneumatic actuator is a vacuum line that is adapted to be connected to a vacuum source such as the engine of the delivery vehicle. A control valve is disposed between the vacuum source and the pneumatic actuator for controlling the activation of the pneumatic actuator. A biasing device engages the door and biases the door towards and open position. Thus, when the latching assembly is actuated the door of the delivery vehicle is unlatched and the biasing device causes the door to assume the open position.
