<p>A duoflow rotating union having a housing, a tubular rotor rotatably mounted in the housing and adapted for coupling to a rotating device which i s adapted to receive fluid conducted through the union and the tubular rotor, a carrier member axially movable in the housing, a rotating first seal member mounted to and rotatable with the rotor, non-rotating second seal means mounted to the carrier member for axial movement within the housing between a first position wherei n the second seal member is spaced from the first seal member and a second positio n wherein the second seal member and the first seal member are engaged togethe r to provide a rotating mechanical seal between the rotor and the tubular carrier , bearing means mounted to the housing for supporting the rotation of the rotor, and internal coolant means associated with the rotating union to cool the bearing means, said coolant means comprising a plurality of fin members equally spaced about and extending radially outwardly from the rotor to provide an air circulation between the rotor and the bearing means to cool the bearing means.</p> |
