Title:
SCROLL COMPRESSOR AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/207784
Kind Code:
A1
Abstract:
This scroll compressor is provided with a stationary scroll, an orbiting scroll, and a thrust plate. An oil holding space is formed on the inside of the thrust plate, a compression chamber is formed between the stationary scroll and the orbiting scroll, the orbiting scroll is provided with an oil supply groove, and the thrust plate has an oil supply hole. The oil supply groove is provided with: an oil inflow section into which lubricating oil flows; an oil flow section, one side of which is in communication with the oil inflow section, and which extends in the rotational direction of the orbiting scroll from the oil inflow section; and an oil outflow section which is in communication with the other side of the oil inflow section and which, when positioned over the oil supply hole, allows the lubricating oil having flowed through the oil flow section to flow out to the oil supply hole side. One orbital rotation of the orbiting scroll includes: a first period of rotation, in which the oil flow section is positioned over the thrust plate, and the lubricating oil is supplied to the oil supply hole through the oil flow section; and a second period of rotation, in which the oil flow section is positioned over the oil holding space, and the amount of the lubricating oil supplied to the oil supply hole through the oil flow section is less than that in the first period of rotation.
