ABSTRACT:
A fluid coupling for interconnecting a liquid-conveying duct in a shaft element to a duct in a hub element, the two elements being rotatable relative to each other. The shaft element has a central passageway subjected to fluid under high pressure and has an enlarged-diameter end communicating with a smaller-diameter portion. The end of the large diameter portion of the shaft element remote from its small diameter portion is subjected to fluid under high pressure in said passageway; while the opposite end of the large diameter shaft portion is subjected to a sealing fluid. The pressure of the sealing fluid is always greater than that of the high-pressure fluid, with the result that the high-pressure fluid will not enter the chamber filled with sealing fluid to decompose it and form an emulsion.
