ABSTRACT:
A door operating mechanism for an air conditioning unit including a bellcrank actuator and pressure plate assembly having an offset pivot point. The outer end of the actuator arm is connected to the door by a resilient linear push-pull rod. The door is releasably retained in a plurality of intermediate open positions by rotation of the actuator between its closed or fully open position and with the push-pull rod having a predetermined length with respect to the door and the actuator in its closed position whereby upon the actuator being retained in its door closed position, the push-pull rod is resiliently bowed to provide a biasing force on the door to retain the same in a substantially air-sealed arrangement with the door opening.
