  • Compressor having a shutdown valve
    Patent number: 8668478
    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.
    Type: Grant

  • Compressor having a shutdown valve
    Patent number: 7959421
    Abstract: A compressor includes a shell, a compression mechanism supported within a suction pressure region of the shell and including a discharge outlet in communication with the discharge chamber, and a discharge valve assembly. The discharge valve assembly includes a valve member, a valve stop including an opening therethrough, and a communication member defining a fluid passage and extending into the discharge chamber from the valve stop toward the discharge outlet in the discharge chamber to provide fluid communication between the opening in the valve stop and a location downstream of the valve stop.
