ユ防止装置。 A Roots pump consisting of a plurality of rotors is arranged in the intake system of an internal combustion engine, and power is transmitted between the rotors on the drive side and the rotor on the driven side by mutually meshing gear means on their respective rotating shafts, and the rotor on the drive side The rotary shaft of the internal combustion engine is connected to the drive shaft of the internal combustion engine so that the rotation of the drive shaft is constantly transmitted, and bypass means is provided for controlling the flow rate that bypasses the Roots pump. A crush prevention device for a roots pump type supercharger of an internal combustion engine, which has means for controlling the amount of bypass to be reduced during load operation.
