Claims

[Claims for Utility Model Registration] In a mechanical non-compression type supercharger installed in the intake passage of an engine, the intake passage of the supercharger is A supercharger for an engine, which comprises a volume chamber that communicates with the working chamber after the stroke ends and before the working chamber defined by the rotor and the rotor housing opens to the discharge port of the supercharger. .
