ABSTRACT:
Rotary joints are provided, to allow fluid to flow from a stationary member to a rotating member. The rotary joints include a housing, configured to fit over the rotating member, a rotatable coupling disposed within the housing, configured to be fixedly attached to the rotating member, and a floating seal system that allows relative movement between the parts being sealed, accommodating thermal expansion and contraction of the rotating member and associated parts.
