Abstract
Abstract A regenerative turbomachine, especially a compressor, in which the working fluid entering via an inlet (16) is divided into slip and counter flow streams. In the each direction, guide means define successive passes through the rotor blades (13) in a generally axial sense. In the slip direction, successive passes (1 DS ,2 DS ,3 DS , etc) are made so as to reintroduce the fluid to the rotor blades at circumferential positions spaces successively in the direction of intended rotor rotation. In the counter flow path successive passes (1 DC ,2 DC ,3 DC , etc) are made so as to reintroduce the fluid at circumferential positions spaced successively in the direction counter to the intended direction of rotor rotation. The slip and counter flow paths are brought together at a common outlet (21), thus obviating the need for a conveh- tional stripper. Intercooling (24) may be provided in at least some passes.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
177 words
A regenerative turbomachine comprising a bladed rotor (11); an annular housing (10) surrounding the rotor and defining an annular flow channel for a working fluid; an inlet port (16) for admitting the fluid to the housing; an outlet port spaced circumferentially of the rotor from the inlet port, by which the fluid can leave the housing; and characterised by guide means for guiding the fluid entering the inlet port through a slip flow (1 DS , 2 DS' 3 DS' etc 19, 20) path and a counter-flow path (1 DC , 2 DC' 3 DC' etc, 19, 20), each flow path making successive passes through the blading (13) in a generally axial sense, wherein in the slip flow path successive passes are made which reintroduce the fluid to the rotor blades at circumferential positions spaced successively in the direction of intended rotor rotation, and in the counter flow path successive passes are made which reintroduce the fluid to the rotor blades at circumferential positions spaced successively in the direction counter to the intended direction of rotor rotation.
Claim 2
Dependent Claim
177 words
A regenerative turbomachine comprising a bladed rotor (11); an annular housing (10) surrounding the rotor and defining an annular flow channel for a working fluid; an inlet port (16) for admitting the fluid to the housing; an outlet port spaced circumferentially of the rotor from the inlet port, by which the fluid can leave the housing; and characterised by guide means for guiding the fluid entering the inlet port through a slip flow (1 DS , 2 DS' 3 DS' etc 19, 20) path and a counter-flow path (1 DC , 2 DC' 3 DC' etc, 19, 20), each flow path making successive passes through the blading (13) in a generally axial sense, wherein in the slip flow path successive passes are made which reintroduce the fluid to the rotor blades at circumferential positions spaced successively in the direction of intended rotor rotation, and in the counter flow path successive passes are made which reintroduce the fluid to the rotor blades at circumferential positions spaced successively in the direction counter to the intended direction of rotor rotation.
Claim 3
Dependent Claim
15 words
A regenerative turbomachine according to claim 1 characterised in that the machine is a compressor.
Claim 4
Dependent Claim
34 words
A regenerative compressor according to claim 2 characterised in that there are provided heat exchangers (24) in the said flow paths for removing heat of compression after at least some of said successive passes.
Claim 5
Dependent Claim
28 words
A regenerative turbomachine according to any one preceding claim characterised in that the annular housing (10) conforms closely to the blade tips so as to minimise leakage therepast.
Claim 6
Dependent Claim
45 words
A regenerative turbomachine according to any one preceding claim characterised in that the axial gap between the rotor blades and the guide means (1 DC , 1 DC' 1 IC , 1 IS , etc) decreases around the rotor circumference from inlet (16) to outlet.
Claim 7
Dependent Claim
33 words
A regenerative turbomachine according to any one preceding claim characterised in that the rotor is provided with one or more hub seals (14) for controlling fluid leakage in the radial and circumferential directions.
Claim 8
Dependent Claim
41 words
A regenerative turbomachine according to any one preceding claim characterised in that the guide means includes one or more flow splitter vanes (17) at the inlet port (16) for assisting in distributing the fluid between the slip and counter flow paths.
Claim 9
Dependent Claim
34 words
A regenerative turbomachine according to claim 6 wherein the flow splitter serves to direct the slip flow portion of the fluid flow at an angular direction different from that of the counter flow portion.
Claim 10
Dependent Claim
12 words
A regenerative turbomachine according to claim 1 and substantially as hereinbefore described.
Claim 11
Dependent Claim
26 words
A regenerative compressor substantially as hereinbefore described with reference to Figures 1 and 2 or Figures 3 and 4, or Figure 7 of the accompanying drawings.
Claim 12
Dependent Claim
26 words
A regenerative compressor substantially as hereinbefore described with reference to Figures 1 and 2 or Figures 3 and 4, or Figure 7 of the accompanying drawings.
