Abstract
The present invention proposes a balance structure of axial submission device for a scroll compressor. The present invention is characterized in that narrower cross section forms on the isolating block partitioning high pressure from low pressure in a scroll compressor such that the direction toward the stationary scroll of low pressure side has larger direct back pressure. Or more than one balance rooms are installed on the isolating block toward the back of the stationary scroll, a first resilient member is placed in the balance room, and the resilient member is lapped on the back of the stationary scroll. More than one anti-pressure rooms can also be installed on the orbiting scroll, and a second resilient member is placed in the anti-pressure room to provide slightly larger pressure for the second resilient member than pressure of the first resilient member when the orbiting scroll starts to rotate.
