Abstract
A compressor having a stationary part and a part oscillating along a main axis (X) as well as a leakage path (L) extending between the stationary part and the oscillating part in the axial direction, wherein multiple chambers, which are arranged axially in succession and extend annularly around the main axis (X), are defined between the stationary part and the oscillating part, wherein a seal, which closes or reduces the leakage path (L) is arranged in at least one chamber. The compressor has at least one bypass which fluidically interconnects two chambers.
Claims16
A compressor, comprising:
- a stationary part,
- a part oscillating along a main axis (X), and
- a leakage path (L) extending between the stationary part and the oscillating part in the axial direction,
- wherein multiple chambers, which are arranged axially in succession and extend annularly around the main axis (X), are defined between the stationary part and the oscillating part,
- wherein a seal, which closes or reduces the leakage path (L), is arranged in at least one chamber,
- wherein multiple separate, independent bypasses are provided, with each bypass fluidically interconnecting two immediately adjacent chambers,
- wherein each bypass has a minimum cross-sectional area M, which is defined by the cross-sectional area at its narrowest point, and
- wherein of two adjacent bypasses, the minimum cross-sectional area M of the bypass that is arranged closer to a high-pressure side (H) of the compressor is smaller than the minimum cross-sectional area M of the bypass which is located closer to a low-pressure side (N) of the compressor.
A compressor, comprising:
- a stationary part,
- a part oscillating along a main axis (X), and
- a leakage path (L) extending between the stationary part and the oscillating part in the axial direction,
- wherein multiple chambers, which are arranged axially in succession and extend annularly around the main axis (X), are defined between the stationary part and the oscillating part,
- wherein a seal, which closes or reduces the leakage path (L), is arranged in at least one chamber,
- wherein at least one bypass is provided, which fluidically interconnects two chambers,
- wherein the stationary part is a sleeve and the oscillating part is a piston, or
- wherein the stationary part is a packing housing and the oscillating part is a piston rod,
- wherein the bypass is provided in the region of the leakage path (L),
- wherein the bypass is a groove, and
- wherein the piston or the packing housing comprises multiple disc bodies, which are arranged axially in succession, wherein the disc bodies comprise a sealing surface, and wherein the groove extends within the sealing surface.
