Abstract:
A rotary union is provided. The rotary union includes a first housing portion, a second housing portion, and a sealing member. The first housing portion has a first fluid passage formed therein and the second housing portion has a second fluid passage formed therein. The second fluid passage is in fluid communication with the first fluid passage. The sealing member is disposed on one of the first housing portion and the second housing portion and is sealingly engaged with a remaining one of the first housing portion and the second housing portion in a substantially similar direction to an axis of rotation of one of the first housing portion and the second housing portion. The rotary union permits axial deviation between a rotating component and a non-rotating component, reduces friction generated within the rotary union, and permits an increased flow rate of a fluid through the rotary union.
