Abstract
A coupling arrangement between a hub and multi-cuvette rotor in analytical photometers, wherein the hub has a projection the section of which has a non-revolving profile and to such end comprises at least one rectilinear segment, the rotor designed for said hub featuring centrally a seating adapted to receive said projection on which hub, peripherally to said projection and distanced from the rectilinear-segment portion, there are arranged radially yieldable elastic elements provided with a portion which projects from said profile so that it elastically associates with the matching seating in the rotor.
Claims7
A coupling device suitable for coupling a multicuvette rotor to an analytical photometer, with the rotor having a central recess with at least one rectilinear-segment portion, comprising a hub fixedly mountable to a rotatable portion of the photometer, the hub having a projection portion shaped to have an exterior profile to fit into the central recess of the rotor and to engage the rotor at the rectilinear-segment portion, characterized by the coupling comprising in addition to the hub a plurality of elastic elements, the elastic elements projecting, in the absence of the rotor, radially outward beyond the exterior profile of the projection portion, and the elastic elements being deformed radially inward by the rotor into the exterior profile of the projection portion, with the deformed elastic elements exerting thrust radially outward against the rotor.
