Patent ID: 7568338

Claim:
A compressor housing for a turbocharger, the compressor housing comprising: an axis to coincide with a rotational axis of a compressor wheel housed by the compressor housing; an inlet insert comprising an inlet port, an annular wall that extends axially downward from the inlet port, a compressor wheel shroud portion inset from the annular wall wherein the shroud portion extends away from the inlet port to a ridge, and a sensor port having an opening along the compressor wheel shroud portion; and a base component that defines, at least in part, a diffuser section and a scroll wherein the diffuser section extends radially outward to the scroll, wherein the base component comprises axially extending bosses to secure the inlet insert to the base component, wherein the bosses provide surface area to aid in cooling the base component and to reduce temperature at contact points for securing the inlet, and wherein a respective space exists between each of the bosses and the inlet insert to reduce heat transfer between the bosses and the inlet insert; wherein the ridge of the inlet insert defines, at least in part, an inlet to the diffuser section and wherein a joint exists between the inlet insert and the base component along a radius in the diffuser section.
