The object is to provide a compressor housing which can suppress blowback of oil. A compressor housing (1) is used in a compressor which uses a compressor impeller (5) provided in an intake air flow path more to a downstream side than a blow-by gas inlet. The compressor housing (1) includes an impeller chamber (2), and an intake air duct (6) which extends along an axis line (C). The duct (6) includes an inner-wall face (61). A step part (67) that is arc shaped along a circumferential direction of the impeller (5) and has a distance along the radial direction of the impeller (5) from the axis line (C) that is farther at a downstream side than at an upstream side thereof is formed in the inner-wall face (61) more to an upstream side along the axis line (C) than the intake air inlet (22).

A supercharger system is disclosed herein having a front end, a rear end, an inlet and an outlet, the system contained within a housing, wherein the supercharger system includes a rotor assembly, and a plurality of intake runners that comprise an interlaced cross-runner pattern, wherein the supercharger system comprises a front drive, front inlet configuration and an inverted orientation.

A supercharged internal combustion engine has a supercharger operable to selectively supply a mass of air from below through above atmospheric air pressure according to the operating requirements of the engine. The supercharger has a shuttle combined with a throttle valve that controls the mass of air directed to an air mass bypass opening and supplied to the internal combustion engine. The shuttle has rollers that ride on rails that allow the shuttle to move to open and close the air mass bypass opening in communication with a casing that directs a mass of atmospheric air and a bypass mass of air interfused with the mass of atmospheric air to an air mass inlet of the supercharger.
