Abstract

DC60 (21/06/53) Multi-cylinder rotary compressors include a baffle that is inserted into the inter The middle of the crankshaft and separates the cylinder. And the roller is attached to the perimeter of the Eccentricity of the crankshaft in such a way that it can rotate The voids enclosed by rollers, cylinders, body, frame and baffles are defined as the compression chamber. The compression chamber is divided into low pressure sections. And the high pressure segment by a rotary blade fixed by each cylinder in order to slide on the corresponding roller, the baffles are formed by two separate discs that are divided along the center line in the direction Along the radial and disc thickness of one of the discs in contact with the rotating blades is set to Than the thickness of the other discs Therefore, several rotary compressors were obtained. Compact and powerful cylinders with less often refrigerant leakage in the compression mechanism.
