ABSTRACT:
An air control valve unit which includes an axially moveable and non-rotating closure member which is responsive to the rotative and non-axial movement of an actuator. The rotative movement of the actuator moves the closure member between a closed position which creates an airtight seal between the closure member and a plurality of open positions each allowing progressive amounts of air to flow from an air source through the valve unit member in fluid communication with the closure member. The closure member and actuator are supported in a cavity of the housing member.
