Title:
COMPRESSOR
Document Type and Number:
Japanese Patent JP2015086716
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compressor utilizing the suction effects of an ejector for supplying oil, for suppressing the complication of a machining process for a driving shaft while ensuring oil supply to a compression mechanism.SOLUTION: An oil supply passage (8) is formed in a driving shaft (7) which drives a compression mechanism (14). The oil supply passage (8) includes an upstream side passage (81) connected to an ejector part (9) where gas refrigerant flows, and a downstream side passage (82) connected to the upstream side passage (81). The downstream side passage (82) is eccentric relative to the axis of the driving shaft (7). Lubricating oil sucked up to the upstream side passage (81) with the sucking action of the ejector part (9) flows in the downstream side passage (82) with centrifugal pump action, and it is supplied to a slide area between a main journal part (74) and an eccentric shaft part (72).
