Title:

ROTARY COMPRESSOR AND REFRIGERATION CYCLE DEVICE

Document Type and Number:

Japanese Patent JP2017180180

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a rotary compressor capable of inhibiting reduction of oil supply efficiency at a compression mechanism part to improve shaft reliability, and a refrigeration cycle device including the rotary compressor.SOLUTION: A rotary compressor includes a container, and a compression mechanism part including oil supply means Y. The compressor mechanism part includes a cylinder 17, a bearing tool 18, a shaft supporting tool 19, an eccentric part 13a provided integrally with a rotational shaft 13, and a roller 23 fitted into the eccentric part. The oil supply means includes: a pumping oil supply hole 30 provided in the shaft supporting tool; lubricant communication passages 35, 36, 37, 38 provided on the rotational shaft, and configured to guide lubricant from the pumping oil supply hole to a pumping slide portion; and an oil lead-out hole 31 provided in the shaft supporting tool, and configured to discharge lubricant, guided to the slide portion, to an oil reservoir.SELECTED DRAWING: Figure 2
