ABSTRACT:
A scroll compressor includes a duct which is located within the discharge chamber of the compressor. The duct receives compressed fluid from the discharge port of the scrolls and directs the flow of the compressed fluid directly to the fluid port extending through the shell. The control of the discharge fluid directly from the discharge port of the scrolls provides a quieter and cooler operating compressor.
