摘要

A side channel compressor having an impeller 2 rotatable around a rotation axis x, wherein a radially outer gap 11 and a radially inner gap 13 to avoid contact between the operating impeller 2 and the housing 3 are housings. 3 and the impeller 2, the impeller 2 has a closed outer edge and an inner edge, and has a plurality of blades 5 in the circumferential direction of the impeller on both sides in the axial direction, and the outer side of the impeller A radially outer gap 11 is formed by forming a peripheral wall 7 whose edge is related to the radial wall 10 of the housing 3, and one or more sealing pieces 14 are formed between A material that is glued circumferentially in a radially outer gap 11 between the two and that wears easily during possible contact with the rotating impeller 2 Impeller 2 is to avoid that biting housing 3 by consisting.
