    CPC classification number: F16J15/342 F16J15/40

    Abstract: This specification discloses a barrier seal in which the pressure of the fluid is being sealed is opposed by the flow rate of a buffer fluid with a movable ring interposed between the two. This ring is movable axially under the influence of the differential which obtains between the pressures of the sealing fluid and buffer fluid. Appropriate passages are provided for the buffer fluid and seals are provided between the movable ring and the shaft and housing in which the barrier seal is installed.

    Abstract: This specification discloses a dry running gas seal for gas processing systems in which a rotating shaft enters a high pressure area. The seal comprises a mating ring presenting a seal face and a seal ring providing two concentric seal faces engaging the seal face on the mating ring and cooperating therewith to define a pressure cavity. A chamber for an inert barrier gas is provided in a fixed housing and communicates with a supply of inert gas under pressure. The seal ring has throttling passage between the barrier gas chamber and the pressure cavity. The seal ring is biased towards the mating ring by springs mounted in the housing. These springs provide the loading force under which the seal faces are urged together. Increase in the pressure of the barrier gas is transmitted through the passages to increase the pressure of the gas in the pressure cavity. This increase results in a decrease of the loading forces.
