Patent ID: 8322138

Claim:
A compressor comprising a housing having an inlet and an outlet, a volume between the inlet and outlet for receiving a impeller wheel rotatable about an axis of rotation; the housing having an inner wall defining a surface over which, in use, radially outer edges of the impeller sweep as the impeller wheel rotates about its axis; the inlet comprising a first tubular wall extending away from the impeller wheel in an upstream direction and forming a gas intake portion of the inlet and a second tubular wall extending away from the impeller wheel in an upstream direction within the first tubular wall and defining an inducer portion of the inlet and a gas flow passage defined between the first and second tubular walls, the gas flow passage being in fluid communication with the impeller wheel; and a crankcase gas ventilation (CCV) conduit having at least a portion that is radially offset from and axially coincident with at least a portion of a substantially axially extending portion of the gas flow passage and having a CCV outlet for delivering CCV gases to the intake upstream of the gas flow passage.
