ABSTRACT:
A scroll compressor comprises a fixed scroll having a spiral-shaped wall body, and a swiveling scroll which has a spiral-shaped wall body and revolves while linking together the two wall bodies; the wall bodies have steps, and side faces of two end plates have high and low bottom faces in correspondence with the steps; a tip seal is provided along a join edge which connects top edges on different sides of each step, and a mechanism is provided therebetween to prevent the tip seals from becoming removed from the join edges. Furthermore, in the same scroll compressor, tip seals are provided respectively in two grooves, and join paths are provided respectively between a high-pressure compression chamber, which is formed with the bottom faces as one section, and the two grooves; the pressure inside the high-pressure compression chamber is used as a pressing force for the tip seals.
