Abstract
The improved shaft seal assembly is disclosed to permit the use of vapor or a combination of a vaporized substance with a carrier on one side of the seal while preventing the movement of the vapor or the vaporized substance from the housing containing said vapor. This novel seal assembly will be an effective seal both during operation and in a static mode. It will also retain the vaporized substance after coalescence so that it may be reclaimed or reused as desired. The novel seal of this invention provides for coalescence in a radial passage between the stator and a second rotor, thus, avoiding any changes, impediments, or variations with relation to the shaft. The novel seal assembly permits the escape of the carrier from the vessel having the vapor or the vaporized substance with a carrier, while retaining the coalesced substance.
