ABSTRACT:
Disclosed is a screw type mechanical supercharger which is small in size but has a large capacity. The supercharger includes a pair of female and male screw rotors held in a mutully meshing condition with each other, and a pair of synchronizing gears mounted for integral rotation with the screw rotors and held in meshing engagement with each other to establish synchronous rotation of the female and male screw rotors. The female rotor has six teeth while the male rotor has three teeth, and the synchronizing gear for the female rotor has a number of teeth equal to twice that of the other synchronizing gear for the male rotor. The female rotor is connected to be driven by a reciprocating internal combustion engine so as to serve as an input power shaft of the supercharger. The screw rotors are preferably formed from a lighter weight material than the remainder of the supercharger.
