  • Hermetic compressor with heat shield
    Patent number: 5649816
    Abstract: A heat shield is disposed in a hermetic compressor between a discharge port and a local area on an interior surface of the outer shell toward which relatively hot compressed gas is directed. The local area of the outer shell is thereby insulated from the high temperature of the discharge gas and the noise and vibrations that are often associated with hot gas impinging on the shell.
    Type: Grant

  • Scroll machine with reverse rotation protection
    Patent number: 5593294
    Abstract: A scroll compressor has a one-way drive for resisting and impeding objectionable reverse movement of the orbiting scroll member. The one-way drive includes a one-way clutch interconnecting a drive shaft with a stationary member of the compressor through a resilient member. Reverse rotation of the drive shaft causes a loading of the resilient member which then operates to cushion the stopping of the reverse rotation of the drive shaft. The one-way drive is inoperative during forward rotation of the drive shaft thus allowing normal operation of the compressor.
