ABSTRACT:
A scroll type fluid displacement apparatus is disclosed. A driving mechanism includes a drive shaft which is rotatably supported by the compressor housing. A crank pin eccentrically extends from an inner end of the drive shaft and is drivingly coupled to a bushing. The bushing has a central axis which is offset from the central axes of the drive shaft and the crank pin. The bushing transmits orbital motion to the orbiting scroll thereby developing line contacts between the spiral elements. A first line can be defined passing through the central axis of the drive shaft and the central axis of the bushing, a second line can be defined passing through the central axis of the bushing and perpendicular to the first line, and a third line can be defined between the central axis of the bushing and the central axis of the crank pin. As the bushing rotates about the crank pin, a reaction force due to the compressed gas is exerted on the central axis of the bushing. When abnormal reaction forces due to the compressed gas are exerted on the central axis of the bushing, a control mechanism reduces the angle between the second line and the third line. Thus, the sealing forces between the fluid respond to changes in compressor output and anti-wearing of the surfaces of the spiral elements can be assured.
