ABSTRACT:
A rotary compressor including an orbiting piston is disposed within a cylinder bore. A crankshaft with an eccentric causes the piston to orbit within the cylinder block. Crescent shaped polymeric washers are interfit between the eccentric and cylinder bore endwalls to reduce friction and endplay therebetween. Curved or whorled grooves on the face of the washer reduce frictional contact area and at the same time increase lubricant flow. Compressor noise is reduced by the ability of the washers to act as resilient stops between the eccentric, crankshaft and cylinder endwalls.
