ABSTRACT:
A chuck for rotating around a rotation axis XAa centrifugal separation bowl secured thereto includes a vat-shaped body for receiving a lower end portion of the separation bowl secured therein with a peripheral rim of the chuck surrounding an outer flank of the separation bowl. The chuck includes a plurality of clutching systems to cooperate with the flank of the separation bowl in securing it to the chuck. The clutching systems include a channel formed in the chuck body with an arcuate path in the peripheral rim of the chuck body. A chain of translatory bodies arranged within the channel includes a proximal translatory body and a distal translatory body in the chain, whereby a force acting on the proximal body and directed outwardly of the rotation axis XAis transmitted through the chain of translatory bodies to the distal translatory body to urge it inwardly towards the rotation axis XAto clutch the outer flank of the separation bowl, whereby the separation bowl is secured to the rotary chuck.
