ABSTRACT:
A rotary joint for delivering a mixed fluid from a radial inlet of a joint element axially through a high speed rotating shaft. Leakproof protection is first realized by one side of a wear block being compressed against an end face of the shaft. A spring presses a washer and an O-shaped ring against the other side of the wear block to prevent leakage and filter most solid impurities. Leakproof protection is also realized by covering the shaft with a seal to isolate leaking fluid from the first protection.
