Abstract: A swinging bucket centrifuge rotor including seating surfaces having shapes which cause buckets seating thereon to be relieved of side loading forces. Each bucket is symmetrical and is pivotally supported by bucket pins that rest in respective spring-loaded carrier assemblies. The spring constants of the springs of the carrier assemblies are selected so that the leading edge of each bucket bottom rests upon a curved surface and clears the respective seating surface before the trailing edge thereof contacts the same. The resulting bucket orientation assures that, upon seating, each bucket rotates until its bucket pins lift slightly off of the surfaces of the respective carrier assemblies.

Abstract: Rotor de centrifugeuse à godets basculants comprenant des surfaces de sièges présentant des formes permettant aux godets reposant sur les sièges d'être soulagés des efforts latéraux de charge. Chaque godet est symétrique et est supporté de manière pivotante par des goujons de godets qui reposent dans des ensembles respectifs de supports à ressorts. Les constantes élastiques des ressorts des ensembles de supports sont sélectionnées de sorte que le bord d'attaque de chaque fond de godet repose sur une surface courbe et laisse libre la surface de siège respective avant que son bord de fuite n'entre en contact avec cette même surface. L'orientation résultante du godet assure que chaque godet tourne sur son siège jusqu'à ce que les goujons de godets décollent légèrement des surfaces des ensembles de supports respectifs.
