ABSTRACT:
The noise of a rotary compressor is reduced by orienting the sliding vane. In particular, the vane is oriented such that the force component which is perpendicular to the vane motion and which tends to jam the vane and create high frictional effects is minimized. The vane is tilted towards the high pressure chamber so as to result in a smaller force component perpendicular to the direction of vane motion, which direction corresponds to the direction of the vane slot itself. The vane may be shifted laterally from its previously known position in order to achieve the same lower friction and lower noise effects.
