  • Floating ring seal means
    Patent number: 4012049
    Abstract: Floating ring seal means for cooling water pumps, especially for cooling water connectors of water-cooled rotors of turbogenerators. A stabilization of the floating ring is achieved through pistons which are pressurized by pump pressure. This results in a ring seal holding force which increases proportionally to an increasing number of revolutions.
