Abstract:
1. A side channel compressor for compressing a gas, comprising: a) a housing; b) a side channel for compressing a gas, the side channel being located in the housing and having a cross-sectional area, wherein the side channel has a varying axial width; c) a gas inlet opening formed in the housing, the gas inlet opening being in flow connection with the side channel for introduction of a gas; d) a gas outlet opening formed in the housing for discharge of the gas to be compressed from the side channel, with the gas outlet opening being in flow connection with the gas inlet opening via the side channel; e) an impeller which is mounted for rotation in the housing and comprises impeller blades disposed in the side channel; f) wherein the cross-sectional area of the side channel decreases from the gas inlet opening towards the gas outlet opening; and g) wherein a course of the cross-sectional area of the side channel has several inflection points between the gas inlet opening and the gas outlet opening, wherein the distance between the inflection points is aperiodic.
