Abstract

Official abstract text for this publication.

A scroll compressor is provided that may include a differential pressure hole formed at or in an orbiting scroll that communicates a high pressure part with an intermediate pressure part, a decompression portion formed in the differential pressure hole and having a pin member inserted therein to decompress oil. An inner diameter D 1 of the decompression portion may be greater than an outer diameter D 2 of the pin member. The decompression portion may include an inlet through which oil may be introduced from the high pressure part into the differential pressure hole, and an outlet through which oil from the differential pressure hole may be discharged into the intermediate pressure part.

First claim
