Title:
SINGLE-STAGE COMPRESSOR WITH BLEED SYSTEM FOR THRUST LOAD ALLEVIATION
Document Type and Number:
Japanese Patent JP2020186724
Kind Code:
A
Abstract:
To provide a compressor that is compact and less complex, and to provide a compressor bearing that is less likely to contaminate the compressor.SOLUTION: A single-stage compressor device 110 includes a housing 136 and a rotating group 148 with a shaft 150 and a compressor wheel 130. The compressor device 110 includes a bleed system 162 fluidly connected to a compressor flow path and configured to receive a bleed fluid from the compressor flow path. The bleed system 162 includes a bleed passage. At least a portion of the bleed passage is cooperatively defined by a back face 168 of the compressor wheel 130 and an opposing surface of the housing 136. The bleed system 162 is configured to pass bleed air from the bleed passage, thereby alleviating thrust loading of the compressor wheel 130 on the rotating group 148.SELECTED DRAWING: Figure 1
