Abstract
There is disclosed a sealed type scroll compressor which decreases a sliding loss between a thrust ring and a orbit scroll and improves the efficiency of the sealed type scroll compressor while preventing the leakage of a refrigerant between a fixed scroll and the orbit scroll, and the compressor provides a relation of F1<F2, in which F1 is an operating pressure applied from the front surface space of the thrust ring to the thrust ring, and F2 is an operating pressure applied from a back surface space to the thrust ring.
