Abstract
An improved scroll compressor having a full thrust surface at which a face of the non-orbiting scroll is in contact with the base of the orbiting scroll is provided with two suction passages. The suction passages extend along circumferential directions at which a substantial portion of the direction of the suction port is tangential. The two suction passages are circumferentially spaced to each be associated with independent compression chambers within the scroll compressor. Due to the tangential component, the refrigerant leaving the ports tends to merge into the compression chambers more rapidly. This results in improved flow, and a reduction in heat transfer.
