Claim 4:
5. A fluid rotary joint for high speed applications comprising:
a first part having a first fluid port and a first gear on an external surface of the first part so that the first part and the first gear rotate synchronously with each other;
a second part having a second fluid port and a second gear on an external surface of the second part so that the second part and the second gear rotate synchronously with each other, the first and second ports being in fluid communication with each other, wherein the first part is rotationally attached to the second part;
a first passage on the first part connected to the first port, a second passage on the second part connected to the second port;
the first passage and the second passage being connected to each other and sealed to form a sealed rotational interface that allows fluid to flow between the first port and the second port via the first and second passages;
wherein the first and second parts rotate and the rotation of the first and second parts are aligned to a common rotational axis.
