PROBLEM TO BE SOLVED: To provide a small size lightweight scroll compressor capable of preventing drop of compression efficiency by using intermediate pressure between suction pressure and delivery pressure as back pressure at low cost. SOLUTION: An independent axial direction minute gap is provided between a main frame 3 and a thrust ring 8. Intermediate pressure between suction pressure and delivery pressure is introduced to the inside of a second back pressure chamber C2 which is the minute gap. COPYRIGHT: (C)2007,JPO&INPIT
