ABSTRACT:
Disclosed is an induction or supercharger system (16) for a piston engine (10) having a Roots type blower (14) for supercharging an air-fuel mixture from a carburetor (12) having primary and secondary throttle valves (60, 62). The induction system includes four ducts (50, 52, 54, 56) which converge at an end into a central area or valve chamber (58) having a butterfly valving member (68) disposed therein. The other end (50a, 52a, 54a, 56a) of the ducts communicate respectively with the carburetor, the supercharger inlet, the supercharger outlet, and the engine combustion chambers. The valves (60, 62, 68) are moved by a linkage mechanism (44) between positions respectively controlling air flow through the carburetor and through the four ducts to the engine. The linkage mechanism includes a lever (72) and linkage assemblies (74, 76) connected between the lever and the valves (60, 62) and (68) respectively. The linkage assemblies include springs (88, 102) which respectively move the throttle valves open and the butterfly valving member closed.
