Abstract

A scroll compressor includes a discharge valve assembly having a valve member, a valve stop supported within the compressor shell and including an aperture there through and a communication member. The communication member defines a fluid passage extending into the discharge chamber from the valve stop toward the first discharge outlet in the discharge chamber and provides fluid communication between the aperture in the valve stop and a location downstream of the valve stop. A first side of the valve member abuts the valve stop when in an open position and the valve stop provides communication between the first side of the valve member and the communication member via the aperture.
