Side channel compressor with housing shells and running wheel

摘要

The invention relates to a side channel compressor, comprising a housing shell and a running wheel. The running wheel is mounted to be rotatable with respect to the housing shell to provide two annular sealing areas between the housing shell and the running wheel. The housing shell between the first and the second sealing area can be made of one piece. The gap dimensions of the first and second sealing areas can be adjusted by means of a disc spring/nut system or a wobble means. A fan impeller may be fixed on the motor shaft, and the housing shell can comprise cooling ribs, wherein the cooling ribs are arranged and formed such that the air conveyed by the fan impeller sweeps through the cooling ribs. One of the annular sealing areas can include a dead volume chamber. The housing shell may be a casting or a machined extruded profile.
