A product may include a bearing housing in which a shaft may be supported by a bearing so that it may rotate. A compressor wheel may be disposed on the shaft. A compressor cover may be connected with the bearing housing, which may form a compressor body and may define a chamber within which the compressor wheel may rotate. A diffuser may extend radially outward from the chamber and may receive gas from the compressor wheel. An inlet may be provided to the compressor body, which may receive a supply of exhaust gas. An EGR distribution cavity may be defined within the compressor body and may extend around the shaft. An EGR inlet channel may extend into the bearing housing from the inlet to the EGR distribution cavity. An EGR passage may extend from the EGR distribution cavity to the diffuser.
A product comprising a bearing housing in which a shaft is supported by a bearing to rotate, a compressor wheel disposed on the shaft, a compressor cover connected with the bearing housing creating a compressor body defining a chamber within which the compressor wheel rotates, a diffuser extending radially outward from the chamber and receiving gas from the compressor wheel, an inlet on the compressor body receiving a supply of exhaust gas, an EGR distribution cavity defined completely within the compressor body and extending around the shaft, an EGR inlet channel extending into the bearing housing from the inlet to the EGR distribution cavity, and an EGR passage extending from the EGR distribution cavity to the diffuser.
A product comprising a bearing housing in which a shaft is supported by a bearing to rotate, a compressor wheel disposed on the shaft, a compressor cover connected with the bearing housing forming a compressor body that defines a chamber within which the compressor wheel rotates and defining an air inlet through which air is directed into the chamber, a diffuser extending radially outward from the chamber and receiving gas from the compressor wheel, an EGR inlet in the compressor body receiving a supply of exhaust gas, an EGR distribution cavity defined in the compressor body and extending around the shaft, an EGR inlet channel extending into the compressor body from the EGR inlet to the EGR distribution cavity, and an EGR passage extending from the EGR distribution cavity to the diffuser.
