Title:
SCROLL COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2020/179051
Kind Code:
A1
Abstract:
This scroll compressor is provided with a fixed scroll and an orbiting scroll having spiral teeth that mesh with each other, and which performs compression by causing the orbiting scroll to orbit around the fixed scroll, wherein the spiral teeth of the fixed scroll and/or the orbiting scroll comprise multiple grooves formed in the lateral surface to circulate a lubricant oil from the tooth base side towards the tooth tip side, each groove is disposed inclined with respect to the center axis direction of the fixed scroll or the orbiting scroll, the end on the tooth tip side is opened, and, between grooves mutually adjacent in the rotation direction of the orbiting scroll in the grooves, non-overlapping sections are formed comprising prescribed intervals where there is no overlap in the rotation direction. By this means, it is possible to suppress reductions in the compression efficiency due to coolant gas leaks, while preventing the tips of the spiral teeth from seizing.
