Abstract

PURPOSE: To aim at the promotion of simplification in structure and miniaturization and lightweightiness by superposing respective end plate peripheral parts of both fixed and swirl scrolls and making them come into slidingly contact with each other, while opposing a projection, formed in the end plate peripheral part of the swirl scroll, to a base surface of a frame.
CONSTITUTION: In the inner part of a hermetically sealed vessel 1, a compressor part with both fixed and swirl scrolls 5, 6 is housed in the upper part and an electric motor part 3 in the lower part, respectively. In this case, each seat surface between an end plate peripheral part of the fixed scroll 5 and another end plate peripheral part 6k of the swirl scroll 6 is superposed at a crescent part F and made slidingly contact with each other. In addition a crescent clearance E is formed between an end plate outer circumferential wall 6j of the swirl scroll 6 and an inner circumferential wall 5k of the fixed scroll 5. With this constitution, a pressure sealing function among a back pressure chamber 20, a side space 6f and a suction chamber 5f is secured by a projection formed in the end plate peripheral part 6k of the swirl scroll 6 and a base surface of a frame 6 being opposed to this projection.
