Title:
SCROLL COMPRESSOR AND REFRIGERATION CYCLE DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/052503
Kind Code:
A1
Abstract:
In the present invention, a scroll compressor is provided with a fixed scroll and a rotating scroll, and by causing the rotating scroll to rotate, a suction chamber and a compression chamber are formed. In addition, the following are provided: a first space which is formed at the back surface center part of the rotating scroll and into which the lubrication oil in a sealed receptacle bottom part is lead so that the pressure in the space becomes close to a discharge pressure; a second space which is provided at the rear surface of the rotating scroll further to the outer peripheral side than the first space, and in which the pressure becomes a pressure between the discharge pressure and a suction pressure; a first oil seepage path that allows some of the oil in the first space to seep into the second space; an oil return flow path that returns a large portion of the oil in the first space to the bottom part within the sealed receptacle; a second oil seepage path for allowing some of the oil in the second space to seep into the suction chamber; and a third oil seepage path that, in accordance with the difference between the pressure in the compression chamber and the pressure in the second space, adjusts the pressure in the second space by releasing the oil in the second space into the pressure chamber.
