Abstract

Apparatus arrangement and Method for providing pressure relief for the locking ring in the rotor of nozzle type centrifugal machines. The locking ring secures the top cover section to the main body section of the rotor bowl, against the internal compression pressure exerted by the stack of separating discs confined between the top and bottom of the rotor bowl. Pressure relief for the locking ring is provided by absorbing or sustaining said internal pressure by means separate from the locking ring. The locking ring thus being relieved of said pressure and of excessive frictional resistance in the thread, is then turnable easily when assembling or disassembling the rotor bowl.
