Abstract
A rotary compressor having a blade slidably carried in a slot in a rotor within the compression cylinder. The opposite ends of the blade are in contact with the cylinder walls at all times, notwithstanding the nonsymmetrical configuration of the cylinder bore. The nonsymmetrical configuration arises from the addition of a cycloidal cam function to the bore equation in the first quadrant and the subtraction thereof from the bore equation in the third quadrant. The cylinder contour resulting from the provision of the cycloidal cam function provides increased operating efficiency in the rotary compressor and allows the length of the transfer slot thereof to be reduced or eliminated so as to reduce recompression volume of the compressor.
