  • External spring supercharger bypass valve
    Patent number: 8046997
    Abstract: A screw compressor type supercharger includes an improved supercharger bypass valve including a spring biasing the bypass valve towards an open position. The spring may be a compression spring integrated into a bypass valve diaphragm, an extension spring extending parallel to a diaphragm arm, or a torsion spring on a bypass valve butterfly shaft. The spring is selected and installed to hold the bypass valve open at all vacuum levels and at up to one PSI of boost, and then to allow the bypass to close between one PSI and six PSI boost, and to be closed at above six PSI boost. The resulting control of the bypass valve prevents damage to the supercharger.
