ABSTRACT:
A hermetic motor compressor includes a shell, first and second scroll members and a closure member extending across a portion of the interior of the shell adjacent one end of the shell to define a discharge chamber. A discharge port in the scroll member located closest to the closure member provides fluid communication between the center of the scroll members and the discharge chamber through an opening in the closure member. A seal member located between the closure member and the scroll member places the discharge port in sealed fluid communication with the discharge chamber.
