ABSTRACT:
A scroll compressor includes a fixed scroll element stationarily mounted on a support and an orbiting scroll element which is caused by an eccentric crank portion of a drive shaft to conduct an orbiting motion relative to the fixed scroll element. The drive shaft is rotatably mounted on the support by respective support bearings and carries a plurality of counterweights which have such respective masses and angular distributions about the shaft that the loadings of the support bearings by the drive shaft during the operation of the scroll compressor are minimized.
