Abstract

In a scroll compressor, it is hard to zone a high pressure chamber and a back pressure chamber which are formed in a back face of an orbiting scroll by a sealing means, increase a feeding amount to the high pressure chamber and the back pressure chamber at a low speed and adjust it at a high speed. A sealing means sealing a high pressure chamber in a center portion of a back face of an orbiting scroll and a back pressure chamber formed by an outer peripheral portion is provided, and a spiral shaped throttle passage is provided between a boss portion in the back face of the orbiting scroll and an outer peripheral surface of an orbiting bearing, thereby constructing an oil feeding route for feeding a lubricating oil to the back pressure chamber from the high pressure chamber.
