Abstract
In a compressor with a scroll compression mechanism having a stationary scroll and a movable scroll, a bearing through which the movable scroll is rotatably connected to a crank portion is disposed in a bearing box. The bearing box is provided for defining a back side room into which high-pressure refrigerant discharged from a discharge hole of an end plate of the movable scroll is introduced. The back side room is partitioned from the compression room by the end plate of the movable scroll to be opposite to the compression room, and a seal member which is disposed to air-tightly partition the back side room and a suction room of the compressor. Thus, a discharge pressure of refrigerant is applied from a back side of the movable scroll only at a position corresponding to the back side room. Accordingly, it is possible to reduce a compression thrust force without using a pressure adjustment valve.
