An impeller assembly comprising a first reinforcing backing plate (9) fixedly attached to a central hub (15), a stacked array of parallel disks (2) fixedly attached to the first reinforcing backing plate, wherein the disks possess a central aperture, and wherein the disks are inter-spaced along a parallel axis; a second reinforcing backing plate (12) fixedly attached to the stacked array of parallel disks, wherein the second reinforcing backing plate possesses a central aperture, whereby, upon radial movement of the central hub, a fluid flows through the central apertures of the second reinforcing backing plate and the stacked array of disks and the spaces between the disks. A plurality of connecting rods (5) are provided to connect the first, second backing plates and the disks. A plurality of spacers (4) are arranged between two adjacent disks to create spaces between the disks. The impeller assembly can be used with various mechanical devices such as, hydroelectric turbines, fluid turbines, turbine transmissions, and pumps of various types.

L'invention concerne un ensemble rotor comportant une première contre-plaque de renfort (9) montée fixe à un moyeu central (15), un groupement empilé de disques parallèles (2) montés fixes à la première contre-plaque, présentant une ouverture centrale et espacés le long d'un axe parallèle ; une seconde contre-plaque de renfort (12) montée fixe au groupement empilé de disques parallèles, possédant une ouverture centrale dans laquelle, lors du mouvement radial du moyeu central, un fluide s'écoule ainsi que dans le groupement empilé de disque et dans les espaces entre ces derniers. Plusieurs barres de liaison (5) sont prévues pour relier les première et seconde contre-plaques et les disques. Plusieurs espaceurs (4) sont prévus entre deux disques adjacents, de sorte que des espaces soient créés entre les disques. L'ensemble rotor peut être utilisé avec divers dispositifs mécaniques, tels que des turbines hydroélectriques, des turbines à fluide, des transmissions de turbine et des pompes de divers types.
