Abstract 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.
In a side-channel ring compressor including compressor medium inlet and outlet openings communicative with the side channel of said compressor, and a channel break disposed between said inlet and outlet openings, the improvement comprising, said side channel break having at least one first outlet opening communicative therewith, and said side channel having a second inlet opening, disposed between said compressor medium inlet and outlet openings, which is communicative therewith at a point in said side channel wherein the pressure of said compressor medium is greater than the medium pressure at said side channel inlet opening and less than the medium pressure at said side channel outlet opening, and a fluid transmission line, coupled to said first and second openings, for exhausting compressor medium from said channel break through said first outlet opening and directing said exhausted medium into said side channel between said compressor medium inlet and outlet openings through said second inlet opening.

In a side-channel ring compressor including compressor medium inlet and outlet openings communicative with the side channel of said compressor, and a channel break disposed between said inlet and outlet openings, the improvement comprising, said side channel break having at least one first outlet opening communicative therewith, and said side channel having a second inlet opening, disposed between said compressor medium inlet and outlet openings, which is communicative therewith at a point in said side channel wherein the pressure of said compressor medium is greater than the medium pressure at said side channel inlet opening and less than the medium pressure at said side channel outlet opening, and a fluid transmission line, coupled to said first and second openings, for exhausting compressor medium from said channel break through said first outlet opening and directing said exhausted medium into said side channel between said compressor medium inlet and outlet openings through said second inlet opening.
Claim 3
Dependent Claim
