<P>PROBLEM TO BE SOLVED: To enable reduction of leakage loss between compression chambers in a scroll compressor and application of stable back pressure, in association with higher efficiency of refrigerating/air-conditioning devices in recent years. <P>SOLUTION: The scroll compressor has a first route 81 for intermittently interconnecting a high-pressure region 30 in the discharge pressure atmosphere and a back pressure chamber 29, a second route 82 for intermittently interconnecting the back pressure chamber 29 and the compression chamber 15, and a third route 83 for interconnecting the high-pressure region 30 and the compression chamber 15, whereby application of stable back pressure can be achieved, and by supplying an optimum amount of oil to both compression chambers 15, leakage loss is reduced, thus achieving improved compression efficiency and higher reliability. <P>COPYRIGHT: (C)2010,JPO&INPIT |
