Abstract
A control system for a hydraulic supercharger system. The control system is specially adapted to control a supercharger system comprising: (A) an hydraulic pump; (B) a supercharger comprising: an hydraulic turbine drive and a compressor driven by said hydraulic turbine drive; (C) a main hydraulic piping means providing an hydraulic circulation loop for hydraulic fluid to flow from said pump, to drive said hydraulic turbine drive, and back to said pump; and (D) a supercharger bypass system comprising a controlled bypass valve and a piping means to permit a portion of said hydraulic fluid to bypass said supercharger turbine drive. The control system includes a bypass control valve arranged to close and partially or fully open the controlled bypass valve. The bypass control valve may be an hydraulic valve controlled by the pressure of the compressed air intake to the engine. The bypass control valve may also be a solenoid valve controlled by a pressure switch connected to sense hydraulic pressure and to apply a voltage to said solenoid valve to open or close said valve upon said hydraulic pressure reaching a predetermined value.
