ABSTRACT:
A rotary fluid union comprises a rotor having a sealing surface and mounted into a rotary member, and a stator having a sealing face and mounted in a stationary housing, the rotor and stator being mechanically disconnected other than by the sealing faces thereof being abutted. The sealing faces are abutted to define a gapless sealing interface, normally disposed in a plane perpendicular to the axis of rotation, but inclined to the axis of rotation in situation where the rotary member deflects radially from coincidence with the axis of rotation, whereby the sealing interface plane is at an angle to the perpendicular plane.
