| 20090022586 | Axial diffuser for a centrifugal compressor - The effective efficiency of a centrifugal compressor can be improved by achieving a uniform distribution of fluid velocity across the outlet end of a fluid passage of an axial diffuser for the centrifugal compressor and a high static pressure recovery ratio Cp in the axial diffuser passage. The cross section of each axial diffuser passage is configured such that a relatively high velocity fluid flow in an upstream part of the diffuser passage is directed toward a negative pressure side of a cross section thereof. It can be accomplished by directing a minor axis of a cross section of the diffuser passage substantially perpendicularly to a direction directed from a center of the cross section of the diffuser passage to the central axial line of an impeller or directing the minor axis toward the central axial line of the impeller. | 01-22-2009 |
| 20100166552 | DIFFUSER FOR A COMPRESSOR - A diffuser is provided having a number of diffuser channels defined by a top wall, bottom wall, and two sidewalls. The sidewalls can be constructed according to an involute of a circle which provides constant interwall distance between the sidewalls along the length of the diffuser channel. The top and bottom walls, however, diverge from one another along the length of the diffuser channel to provide a desired diffusion. | 07-01-2010 |
| 20140199167 | COMPRESSOR HOUSING FOR AN AIR CYCLE MACHINE - A compressor housing for an air cycle machine is provided. The compressor housing includes a body having a compressor volute configured to provide centrifugal compression in the air cycle machine. A mating surface is integrally formed with the body. The mating surface includes a plurality of substantially equally angularly spaced bosses. The bosses include a first boss type at a first radial distance and configured to receive a threaded fastener coupled to a turbine nozzle of the air cycle machine. The bosses also include a second boss type at a second radial distance configured to secure a seal plate of the air cycle machine. The second radial distance is less than the first radial distance. A ratio of a number of the bosses of the first boss type to the second boss type is 17 to 2. | 07-17-2014 |
| 20140271170 | CENTRIFUGAL COMPRESSORS AND METHODS OF DESIGNING DIFFUSER VANES FOR THE SAME - Centrifugal compressors, methods of forming centrifugal compressors, and methods of designing diffuser vanes in centrifugal compressors are provided herein. In an embodiment, a method of designing diffuser vanes includes providing an initial two-dimensional diffuser vane layout including initial diffuser vane peripheries radially spaced about an axis. The initial diffuser vane peripheries are rotated using a computer processor to produce rotated diffuser vane peripheries having offset trailing ends relative to the initial diffuser vane peripheries. The rotated diffuser vane peripheries are circumferentially shifted about the axis to produce shifted diffuser vane peripheries. Leading ends of the shifted diffuser vane peripheries are offset from the leading ends of the initial diffuser vane peripheries. Diffuser vane surfaces are generated that connect the shifted diffuser vane peripheries to the corresponding initial diffuser vane peripheries to form diffuser vanes in a twisted configuration. | 09-18-2014 |
| 20140328676 | COMPRESSOR - A compressor that includes an impeller, a diffuser and a shroud. The diffuser includes vanes and one or more projections, each of which extends from a top of a vane. The shroud includes one or more holes. The shroud covers the impeller and the diffuser such that each projection protrudes through one of the holes. The shroud is then secured to the projections by an adhesive. | 11-06-2014 |
| 20150354593 | TURBINE NOZZLE AND MANUFACTURING METHOD THEREOF - A manufacturing method of a turbine nozzle is provided. The method includes: (A) forming a first part which includes a blade and one of an inner ring portion and an outer ring portion integrated therein; (B) forming the other of the inner ring portion and the outer ring portion as a second part; (C) combining the first part and the second part such that an outer side surface of the inner ring portion and an inner side surface of the outer ring portion are arranged to oppose each other and that a gap is formed between the blade of the first part and the second part; and (D) flowing a brazing material in a molten state into the gap to braze the blade of the first part and the second part. | 12-10-2015 |

| 20140064953 | CENTRIFUGAL COMPRESSOR DIFFUSER VANELET - A system, in certain embodiments, includes a centrifugal compressor diffuser including a flow path having a first surface and a second surface defining opposite axial sides of the flow path. The centrifugal compressor diffuser also includes multiple vanes extending from the first surface to the second surface of the flow path. A first profile of each vane varies along an axial direction. The centrifugal compressor diffuser further includes multiple vanelets extending from the first surface toward the second surface in the axial direction. A first axial extent of each vanelet is less than a second axial extent of the flow path. In addition, a second profile of each vanelet varies along the axial direction and/or the vanelets form a non-periodic pattern around a circumference of the flow path. | 03-06-2014 |
