Abstract
Throttle ring for a piston compressor, the throttle ring comprising an axially running ring axis (Ar), an axial height (h), a radially inner running surface and a radially outer circumferential surface, and an upper flank and a lower flank, wherein the upper flank faces the compression space of the piston compressor when the throttle ring is in intended use. The running surface has at least one circumferential groove in the circulating direction, which is connected to the radially outer circumferential surface by at least one radial bore.
Claims17
A throttle ring for a piston compressor, said throttle ring having an axially running ring axis, an axial height, a radially inner running surface and a radially outer circumferential surface, and an upper flank and a lower flank, the upper flank facing a compression space of the piston compressor when the throttle ring is used as intended, the running surface having grooves which run around in a circulating direction and are connected to the radially outer circumferential surface by at least one radial bore, and wherein the grooves are arranged in a range of 10% to 90% relative to the axial height of the throttle ring.
A throttle ring for a piston compressor, said throttle ring having an axially running ring axis, an axial height, a radially inner running surface and a radially outer circumferential surface, and an upper flank and a lower flank, the upper flank facing a compression space of the piston compressor when the throttle ring is used as intended, the running surface having grooves which run around in a circulating direction and are connected to the radially outer circumferential surface by radial bores, wherein the radial bores extending from the respective groove to the circumferential surface are arranged axially symmetrically to one another with respect to the ring axis.
A throttle ring for a piston compressor, said throttle ring having an axially running ring axis, an axial height, a radially inner running surface and a radially outer circumferential surface, and an upper flank and a lower flank, the upper flank facing a compression space of the piston compressor when the throttle ring is used as intended, the running surface having grooves which run around in a circulating direction and are connected to the radially outer circumferential surface by radial bores, wherein the grooves have different groove widths.
