<P>PROBLEM TO BE SOLVED: To solve a problem that, in a scroll compressor, it is hard to zone a high pressure chamber and a back pressure chamber which are formed in a back face of an orbiting scroll by a sealing means, increase a feeding amount to the high pressure chamber and the back pressure chamber at a low speed and adjust it at a high speed. <P>SOLUTION: This compressor includes: the sealing means that seals the back pressure chamber disposed in the center part of the back face of the orbiting scroll and the high pressure chamber formed on an outer periphery; and a spiral throttle passage disposed between a boss on the back face of the orbiting scroll and an outer peripheral surface of the orbiting bearing. This forms a lubricating passage which supplies lubricating oil from the high pressure chamber to the back pressure chamber. <P>COPYRIGHT: (C)2012,JPO&INPIT |
