Abstract
The air induction system ( ) includes a supercharger ( ) and a valve assembly. The valve assembly comprises a valve ( ) and a valve control mechanism ( ). The supercharger ( ) receives air through a supply opening ( ) and pressurizes it. The valve ( ) is in communication with the supply opening ( ) to control air supply thereto. The control mechanism ( ) is coupled to the valve ( ) and causes it to vary the air supply to the opening ( ) in response to air pressure conditions downstream from the supercharger ( ). In one embodiment, the control mechanism ( ) varies the air supply responsive to air pressure in the intake in order to both throttle the supercharger ( ) as well as substantially eliminate undesirable surge conditions therein. Alternately, the control mechanism ( ) varies the air supply responsive to air pressure in the inlet ( ) of a turbocharger ( ) to provide supercharged air thereto at a substantially constant pressure.
