Abstract
A rotary compressor includes a cylinder with a cylindrical compression chamber. A cylindrical piston is eccentrically movable within the chamber. A vane slot extends outwardly in the cylinder from and communicates with the chamber. A vane is reciprocatingly mounted in the vane slot for selective protrusion into and retroaction from the chamber to contact the piston. At least one noise reduction slot projects into the cylinder from its outer peripheral wall near the vane slot and extends completely between the ends of the cylinder.
