Abstract
Hydraulic motor system for providing differential rotation of rotors in centrifuge has a drive and gearing system inside the casing of the unit, driven by a stationary pump. Planetary gearing transmission is used and differential speed is adusted by varying feed to hydraulic motor. A safety valve to regulate oil pressure compensates for unit blockages.
