ABSTRACT:
An air flow control valve assembly for selectively directing air flow through the air chambers of a heating, ventilating and air conditioning (HVAC) module. The assembly includes a support arm rotatably secured at one end to a flat plane valve and defining a first rotation axis therewith, and a second end rotatably secured to the housing of the module and defining a second rotation axis which is parallel and spaced from the first axis. The valve is actuated to move through an arcuate path about the second axis to selectively position the valve in sealing contact with first and second ports for controlling air temperature in a passenger compartment of a vehicle.
