Abstract
A device for supplying feedwater to, and conveying feedwater from, a shaft tube assembly (20,22) of a machine having a rotary part, which assembly (20,22) has a longitudinal axis about which the assembly (20,22) rotates together with the rotary part, the device being composed of a housing which includes a cylindrical casing (2) having a cylindrical passage extending between its axial ends and a lateral feedwater passage (6) communicating with the cylindrical passage, a conduit member (8) having a second feedwater passage (10) and coupled to one axial end of the casing (2) to form a sealed joint with the casing (2), the conduit member (8) being positioned relative to the casing (2) such that the second feedwater passage (10) communicates with the cylindrical passage, and a closing member (12) coupled to the second axial end of the casing (2) to form a sealed joint with the casing (2), the closing member (12) having a circular opening coaxial with the cylindrical passage of the casing (2 ), the housing being constructed to receive the shaft tube assembly (20,22) such that the shaft tube assembly (20,22) extends through the circular opening of the closing member (12) and into the cylindrical passage of the casing (2) so that each feedwater passage (6,10) communicates with a respective one of a feedwater inlet (46) and feedwater outlet (48) of the assembly (20,22).
