Abstract : A sealing device for sealing the joint between a through shaft and a wall or partition. The sealing device is comprised of a relatively thin, flexible diaphragm sandwiched between nonrotatable pressure plates which are floatably positioned between two inclined cam elements. The cam elements are carried by two axially aligned rotatable shafts. When one of the shafts is rotated, the cam elements will force the other shaft to rotate. The intervening pressure plates do not rotate but merely wobble when the shafts are torqued. The sealing diaphragm, being interposed between the pressure plates, completely seals the opening of entry of the shafts from one another. (Author)
