Compressor housing

摘要

Compressor housing (15) for turbocharger forming at least a part of a compressor wheel compartment (21) for a compressor wheel (9), and a spiral shaped compressor passage (23). The spiral passage comprises an outlet (51) for supplying compressed air to at least one cylinder for combustion. A start of a loop of the spiral shaped compressor passage is formed by a closed end such that the air collected in the spiral shaped compressor passage near the closed end is forced to flow through the loop of the spiral shaped passage towards the outlet.
