Compressor for supercharging combustion engine

A compressor used for supercharging a combustion engine is disclosed. The compressor comprises a compressor shell (1) provided with a volute (2); a compressor impeller (3) arranged in the compressor housing (1), the compressor impeller (3) rotating about an axis (A) and transporting gas into the volute (2); and an inlet channel (4), wherein at least the end portion of the inlet channel (4) is oriented in the direction of the axis (A), such that gas is guided in the axial direction to the compressor impeller. An exhaust gas duct (5) terminates in an inlet duct (4) upstream of the compressor impeller (3), and the exhaust gas duct (5) can be closed by means of a valve (6), a housing (8) of a drive (7) of the valve (6) being integrally formed with the compressor housing (1). 本发明公开了一种用于使燃烧发动机增压的压缩机，所述压缩机包括：具有蜗壳(2)的压缩机壳体(1)；安排在所述压缩机壳体(1)中的压缩机叶轮(3)，所述压缩机叶轮(3)围绕轴线(A)转动并将气体运输到所述蜗壳(2)中；以及入口通道(4)，至少所述入口通道(4)的端部部分被定向在所述轴线(A)的方向上，以便沿所述轴向方向将气体引向所述压缩机叶轮，其中，排气通道(5)终止在所述压缩机叶轮(3)上游的入口通道(4)中，并且其中，所述排气通道(5)可以借助于阀(6)关闭，其中，所述阀(6)的
