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 (35) whose discharge port is open to a joint surface of a main frame (3) and a fixed scroll (4) is provided, and a throttle pin (353) is inserted in the oil supply passage (35) with a predetermined clearance to regulate the inflow quantity of lubricating oil (0). 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 (43).
