Patent ID: 8380024

Claim:
An integrated electro-optical fluid rotary joint for optical signals, electrical power, and/or signal(s), as well as fluids across a common rotary-stationary interface comprising: a main stator with a central hole and an sealed internal space; a couple of bearings; a main rotor with a central hole, being rotatable relative to said main stator through said bearings; an electrical rotary joint, or slip ring, with commuters and conductive rings; a fiber optical rotary joint, with a rotor assembly, and a stator assembly; a fluid rotary joint, having a sealing assembly with a sealed annular space, and related with said main stator and said main rotor; and the annular space between the opposing peripheral surfaces of said main stator and the main rotor being divided into at least three portions along the axial direction: the first portion, the second portion and the third portion; said main stator further comprise: the first end surface as well as second end surface, and a fluid passage at said second portion; and said the main rotor further comprise: the first end surface related to said first end surface of said main stator, and second end surface related to said second end surface of said main stator.
