  • Patent number: 8186981
    Abstract: There is disclosed a scroll compressor having an object of stabilizing the moving of an orbit scroll while suppressing the start load of the scroll compressor. In the scroll compressor, a slide bush having a slide face forming a predetermined angle with respect to the direction of gas load of a gas in a compression chamber is interposed on an eccentric shaft of a shaft for driving the orbit scroll, so that when the load of the gas in the compression chamber is applied, the eccentric amount of the eccentric shaft increases. The scroll compressor includes a spring member interposed between the slide bush and the eccentric shaft and configured to constantly urge the eccentric shaft to decrease the eccentric amount of the eccentric shaft, and this spring member urges the eccentric shaft to press the eccentric shaft onto the slide face of the slide bush.
