Abstract:
1. A sealed type scroll compressor comprising: a compression element having a fixed scroll and a orbit scroll; and a motor element which drives the orbit scroll being in the orbit by its axis, a structure for supporting movably the orbit scroll in the axial direction, guiding a compressed refrigerant in a compression element into a back surface space of a thrust ring provided on the back surface of the orbit scroll, and pressing the orbit scroll onto the fixed scroll by the thrust ring while the compression element compresses the refrigerant, wherein the compressed refrigerant in the compression element is guided into a front surface space of the thrust ring, the front surface space is positioned between the back surface of the orbit scroll and the thrust ring, to provide a relation of F the pressure of the entire compressed refrigerant guided into the back surface space is substantially equal to the pressure of the entire compressed refrigerant guided into the front surface space.
