ABSTRACT:
A scroll type compressor with an enhanced sealing arrangement includes two sealing rings, mounted one between a first part of a gliding block and a first chamber of a fixed scroll and another one between a second part of the gliding block and a second chamber of the fixed scroll, respectively. The sealing ring has a U-shape cross section characterized in having a center depth smaller than half of a total height of the cross section. By providing such sealing rings, damage in mounting the sealing rings can be reduced to a minimum, possible leakage from the damage can be avoided, the assembly process in producing the compressor can be improved, and the compressor can be successfully merchandized.
