Claims

[Claims for Utility Model Registration] A turbocharger housing includes a pair of rotors that engage and rotate, and air taken into the housing through an intake introduction passage is opposed to the intake introduction passage with the pair of rotors sandwiched between the two rotors. In a mechanical supercharger that pressure-feeds air toward an air discharge port formed on the side, the intake air introduction passage is configured with two systems corresponding to each rotor, and the tip of one lobe of the rotor that comes into contact with the inner wall of the housing is At a rotor rotational position in contact with a boundary between an inner wall of the housing and the air discharge port, intake air introduction passages are provided in a portion of the inner wall of the housing upstream of a contact point of the inner wall of the housing at the tip of another adjacent lobe of the rotor that follows the lobe. What is claimed is: 1. A mechanical supercharger, characterized in that the intake air introduction passages are opened and each intake passage is formed so as to be oriented toward the adjacent lobe at the rotor rotational position.
