Abstract
A scroll compressor supplies an optimum quantity of lubricating oil to a refrigerant compressing section and restrains a decrease in compression efficiency caused by gas leakage. An oil supply passage () whose discharge port is open to a joint surface of a main frame () and a fixed scroll () is provided, and a throttle pin () is inserted in the oil supply passage () with a predetermined clearance to regulate the inflow quantity of lubricating oil (). Also, a groove-shaped connecting portion is formed in the joint surface on the main frame side to connect the discharge port to a compression chamber ().
