Abstract

A scroll compressor includes a first oil supply passage communicating with a first compression chamber formed between an inner circumferential surface of a fixed wrap and an outer circumferential surface of an orbiting wrap, and a second oil supply passage separated from the first oil supply passage and communicating with a second compression chamber formed between an outer circumferential surface of the fixed wrap and an inner circumferential surface of the orbiting wrap, wherein the first oil supply passage includes an oil supply guide portion provided in a thrust surface of the fixed scroll in contact with the orbiting scroll to define a part of the first oil supply passage, whereby communication between the first and second compression chambers can be prevented, thereby suppressing leakage between the compression chambers, stabilizing behavior of the orbiting scroll, and facilitating formation of the orbiting scroll.
