Abstract
A compressor is disclosed, which has an inflow channel for guiding a compression medium into a compressor housing, a pressure chamber formed within the compressor housing, and a liner segment with nozzles that transport the compression medium from the pressure chamber to a rotor. The nozzles are formed in the liner segment as a plurality of nozzles arranged in a group in fan-like manner.
Claims19
A compressor having
- an inflow channel (110), which guides a compression medium into a pressure chamber (112) formed inside a compressor housing (111), and
- a liner segment (120) with a plurality of groups of nozzles, each group of nozzles comprising a plurality of nozzles, and each nozzle (123) transports the compression medium from pressure chamber (112) to a rotor, the plurality of nozzles within each respective group of nozzles being aligned adjacent to one another in a circumferential direction of the liner segment, and the groups of nozzles being circumferentially spaced apart along the liner segment,
- is hereby characterized in that
- the pressure chamber (112) is positioned between the liner segment (120) and the compressor housing (111),
- each nozzle (123) has an entrance section (124) and an exit section (125), the entrance section extending linearly along an entrance axis, the exit section extending linearly along an exit axis, and the entrance axis and exit axis being at an angle to one another;
- each nozzle (123) includes a deflection region located where the entrance section (124) and exit section (125) meet;
- wherein each nozzle extends from a first side of the liner segment to a second side of the liner segment, so that the entrance section (124) is in facing relation with the compressor housing (111), and the exit section (125) is in facing relation with the rotor;
- and
- wherein each nozzle directs the compression medium in a downstream direction.

A compressor having
- an inflow channel (110), which guides a compression medium from radially outside of a compressor housing (111) into a pressure chamber (112) formed inside the compressor housing (111), and
- a liner segment (120) with a plurality of groups of nozzles formed in liner segment (120) and circumferentially spaced apart along the circumference of liner segment (120), each group of nozzles having a plurality of nozzles (123) which transport the compression medium from pressure chamber (112) to a rotor having rotor blades, the plurality of individual nozzles in each respective group being aligned adjacent to one another in a circumferential direction of the liner segment;
- a pocket (115) defined by a radially outwardly extending wall in the compressor housing (111);
- is hereby characterized in that
- the plurality of nozzles (123) in liner segment (120) is positioned upstream from the rotor blades;
- and
- the rotor rotates in a circumferential direction;
- and
- each nozzle, including a deflection region, deflects the compression medium in the circumferential direction of the rotor;
- wherein the pressure chamber (112) is positioned between the liner segment (120) and the compressor housing (111);
- further wherein each nozzle extends from a first side of the liner segment to a second side of the liner segment, so that each nozzle (123) has an entrance section (124) in facing relation with the pocket defined the compressor housing (111), and each nozzle has an exit section (125) in facing relation with the rotor;
- wherein in each nozzle the respective deflection region is located where the respective entrance section (124) and the respective exit section (125) meet;
- and
- wherein each nozzle directs the compression medium in a downstream direction;
- and
- wherein the entrance section (124) has an entrance swirling.
