ABSTRACT:
Objectionable noise in a rotary compressor is reduced by placing cavities in the sliding vane and/or the rolling piston. The cavities are used to change the local compliance of surfaces which impact one another to generate the objectionable noise. The change in the compliance of impacting surfaces is used to change the frequency of the noise generated by the impacting surfaces.
