A side-channel ring compressor including compressor medium inlet and outlet openings communicative with the side-channel thereof, and a channel break disposed between the inlet and outlet openings. The channel break has at least one first outlet opening communicative therewith, and the side channel has a second inlet opening, disposed between the compressor medium inlet and outlet openings, which is communicative with the side channel at a point at which the pressure of the compressor medium is greater than the medium pressure at the side-channel inlet opening and less than the medium pressure at the side-channel outlet opening. A fluid transmission line is coupled to the first outlet and second inlet openings, and directs compressed gas from the channel break into the side channel between the compressor medium inlet and outlet openings. At least part of the compressed gas trapped between the blades of the impeller of the compressor is thereby removed. |
