F25B 13/00
F25B 31/02

Abstract:

A compressor includes a housing, a shaft that is rotated relative to the housing to compress a working fluid, and a foil bearing that supports the shaft. The foil bearing includes a top foil. The foil bearing is a foil gas bearing that is backed up by a ball bearing, or a mesh foil bearing with an actuator to compress a wire mesh dampener. A heat transfer circuit includes a compressor and a working fluid. The compressor includes a shaft that is rotated to compress the working fluid, and a foil bearing for supporting the shaft as it rotates.

Abstract:

A porous gas bearing is disclosed. The porous gas bearing includes a housing having a fluid inlet and an aperture. A porous surface layer is disposed within the housing surrounding the aperture in a circumferential direction. The porous surface layer includes a plurality of segments arranged in a longitudinal direction of the aperture. The porous surface layer is in fluid communication with the fluid inlet. A damping system includes a plurality of dampers. The plurality of dampers is disposed circumferentially about the aperture. The plurality of dampers is arranged in between a first segment of the plurality of segments of the porous surface layer and a second segment of the plurality of segments of the porous surface layer.
