Abstract:
A scroll compressor according to the present disclosure includes a fixed scroll, an orbiting scroll forming first and compression chambers with the fixed scroll, first and second compression chamber oil supply holes formed through the orbiting scroll to communicate with the first compression chamber and the second compression chamber, respectively, wherein when a section in which the first compression chamber oil supply hole is opened toward the first compression chamber is a first oil supply section and a section in which the second compression chamber oil supply hole is opened toward the second compression chamber, a non-overlap section between the first oil supply section and the second oil supply section may be longer than an overlap section between the first oil supply section and the second oil supply section, so as to prevent communication between the first and second compression chambers, thereby suppressing leakage between the compression chambers.
