Abstract
A scroll compressor includes a discharge valve assembly for blocking compressed refrigerant flow from the discharge chamber through the scroll members. This blocking of flow results in an increased performance for the scroll compressor by minimizing the recompression volume due to the configuration of the value assembly and thus the elimination of reverse rotation at shut down. The discharge valve assembly includes a valve seat, a disc shaped valve member, a retainer, a spring and a stop secured within a recess formed within the scroll member.
