A water-cooled compressor housing assembly for a turbocharger includes a compressor housing that defines an open-ended cavity extending axially downstream into the compressor housing, and a separately formed cover that is affixed to the compressor housing so as to close the open end of the cavity and thereby define a coolant passage for a liquid coolant to be circulated through. A coolant inlet and a coolant outlet are provided for supplying coolant into and exhausting coolant from the coolant passage. The compressor housing has a simplified geometry that is manufacturable by sand casting without needed a sand core for the coolant passage, or by die casting.

A compressor includes a compressor housing defining a cavity, and a compressor wheel disposed in the cavity, the compressor housing defining an inlet for leading air into the compressor wheel, a discharge volute for receiving air compressed by the compressor wheel, and a recirculation duct connected to the inlet at a location upstream of the compressor wheel. A recirculation valve is disposed between the discharge volute and the recirculation duct for regulating air flow through the recirculation duct into the inlet. The recirculation duct defines multiple parallel channels, the multiple parallel channels respectively conducting multiple parallel streams of air from the recirculation valve into the inlet.
