Abstract

A scroll compressor is provided that may include a casing, a main frame, a rotational shaft, an orbiting scroll, a fixed scroll, and an oil supply guide. A second oil supply guide of the oil supply guide may be disposed in at least one of the orbiting scroll or the fixed scroll and extend along a thrust bearing surface between the orbiting scroll and the fixed scroll to provide communication between a first oil supply guide and a compression chamber having a lower pressure than an oil storage space. This may produce a great pressure difference between ends of an oil supply passage including the first oil supply guide and the second oil supply guide, and allow smooth oil supply using differential pressure to the thrust bearing surface between the fixed scroll and the orbiting scroll.
