Abstract
The invention relates to a stabilizer of a compressor, in particular of a radial compressor or diagonal compressor. The stabilizer comprises a first annular stabilizer chamber which encloses a main flow channel in the intake region of a compressor wheel. The stabilizer further comprises a second annular stabilizer chamber which encloses the first annular stabilizer chamber. The invention further relates to a compressor, in particular a radial compressor or diagonal compressor, comprising the stabilizer according to the invention, and to a turbomachine, in particular a turbocharger, comprising the compressor.
Claims15
A stabilizer of a compressor, comprising:
- a first annular stabilizer chamber, wherein the first annular stabilizer chamber surrounds a main flow channel in an intake region of a compressor wheel, said compressor having a direction of flow from the intake region toward the compressor wheel,
- a second annular stabilizer chamber, wherein the second annular stabilizer chamber surrounds the first annular stabilizer chamber,
- an annular separating element arranged between the first annular stabilizer chamber and the second annular stabilizer chamber,
- a first downstream inlet channel defined at least in part by the annular separating element, wherein the first annular stabilizer channel communicates with the main flow channel via the first downstream inlet channel extending parallel to a radial direction, and wherein the first downstream inlet channel is not defined in any part by a housing of the compressor, and
- a second downstream inlet channel defined at least in part by the annular separating element and the housing of the compressor, wherein the second downstream inlet channel is separate from the first downstream inlet channel, and wherein the second annular stabilizer channel communicates with the main flow channel via the second downstream inlet channel extending parallel to the radial direction,
- wherein at least one of the following applies:
- at least one first flow guiding element is arranged in the first downstream inlet channel, wherein the first annular stabilizer chamber extends along the direction of flow transversally to the radial direction, and at least one second flow guiding element is arranged in the second downstream inlet channel, wherein the second annular stabilizer chamber extends along the direction of flow transversally to the radial direction.
