Abstract
Abstract AN AUTOMATIC CONTROL MECHANISM IS PROVIDED WHICH PERMITS A TURBO SUPERCHARGER TO BE FUNCTIONAL AT LOW ENGINE SPEEDS WITHOUT SACRIFICING EFFICIENCY AT THE HIGHER ENGINE SPEEDS. THE CONTROL MECHANISM OF THE INVENTION ALSO SERVES TO REMOVE THE INHERENT ROTATIONAL LAG OF THE TURBO SUPERCHARGER WHEN THE ENGINE IS SUDDENLY CALLED UPON TO PRODUCE A HIGH POWER OUTPUT. THE MECHANISM OF THE INVENTION INVOLVES A DIVERTER VALVE WHICH IS OPERATED, FOR EXAMPLE, BY INTAKE MANIFOLD PRESSURE, AND WHICH DIVERTS EXHAUST GASES THROUGH A SINGLE FLOW CHANNEL AT LOW EN- GINE SPEEDS AND THROUGH TWO SEPARATE FLOW CHANNELS AT THE HIGHER ENGINE SPEEDS.
