1. A centrifugal separator for separating solid contaminants from a liquid supplied thereto at elevated pressure, said separator comprising:

  • a housing having a base part and a cover part releasably secured to each other, and a separation rotor contained in said housing between the base and cover parts, said rotor being mounted in said housing by a spindle so as to be rotatable about an axis extending between the base and cover parts and to be displaceable along the axis between limits defined by said base and cover parts;

    wherein said centrifugal separator further comprises a rotor restraint comprising;

    a restraining surface forming part of, or carried by, the rotor and extending radially and circumferentially of the rotor and facing away from the base, and an abutment carried by the base and having an abutment surface overlying the restraining surface at or beyond the limit of axial displacement of the rotor from the base defined by the cover, said abutment being operable to prevent further axial displacement of the rotor away from the base if the cover is removed.
