Abstract
A centrifugal separator ( ) for an engine includes a rotor ( ) mounted within a housing ( ) for rotation on hollow spindle ( ) to the end of which oil is supplied at high pressure to enter the rotor. To prevent the rotor from flying from the base and oil spraying if the cover ( ) is removed without shutting off the oil supply via optional valve ( ), a rotor restraint ( ) is provided in the form of a ring ( ) which surrounds and overlies a flange of the rotor. The ring may be complete or discontinuous and may also include an interlock to prevent attachment of the cover and/or supply of oil if the ring is not in place.
