Abstract

PURPOSE:To improve the compression efficiency by covering by means of heat- insulating members the working gas passage of a fixed scroll and a part of the inner-wall part in the space formed by the fixed scroll and a turning scroll, thus preventing the heat conduction to the working gas caused by the discharged gas with a high temperature. CONSTITUTION:The inner surface of the suction passage 6 of a fixed scroll 2 and inner walls on the fixed scroll 2 side and on the turning scroll 4 side of the intake chamber 5 which are a part of the space formed between a turning scroll 4 and the fixed scroll 2 are covered with heat-insulating members 25 and 26 respectively. The heat-insulating parts of the intake chamber 5 comprises the lap bottom part 2c and the lap side-wall part 2d of the fixed scroll 2, and the lap bottom part 4c and the lap side-wall part 4d of the turning scroll 4. The heat- insulating member 25 prevents the conduction of the heat of the fixed scroll 2 to the intake gas 3, and the heat-insulating member 26 prevents the conduction of the heat from the turning scroll 4 side to the intake gas, thus improving the compression efficiency.
