Abstract:

Rotary seal systems and apparatus communicate a working fluid between first and second associated machine components that are rotatable relative to each other. A rotary seal apparatus includes annular inner and outer sleeve members for engaging the associated machine components, and a sealing system disposed between the inner and outer sleeve members. The sleeve members each define respective passageways extending through sleeve bodies thereof, and the sealing system forms a fluid chamber between the sleeve bodies defining an annular fluid channel operable to communicate the working fluid between fluid ports of the associated machine components via the passageways of the sleeve members. The rotary seal system may be provided in combination with an axle having a radial passageway opening outside of axially spaced apart first and second bearings carrying the axle.
