Title
(EN) MICRO POWER GENERATING DEVICE
(FR) DISPOSITIF DE GENERATION DE PUISSANCE DE PETIT FORMAT
Abstract
(EN)
There is provided a micro power generating device. A compressor impeller and a turbine wheel are coupled to the ends of a rotating shaft. A cooler is provided for lowering a temperature of the compressed air from the compressor impeller. The compressed air is mixed with the fuel and combusted in a combustion chamber. An air foil thrust bearing for supporting the rotating shaft has a thrust collar coupled to the rotating shaft, as well as a pair of thrust discs located apart from the thrust collar and fixed to the housing. Impeller type seals are formed at both surfaces of the thrust collar and impulse turbine blades are formed at the periphery of the thrust collar. A generator is positioned between the air foil thrust bearing and the compressor impeller. A portion of the cool air is bypassed toward the generator and the impulse turbine blades from the cooler.

L'invention concerne un dispositif de génération de puissance de petit format. Un rotor de compresseur et une roue de turbine sont couplés aux extrémités d'un arbre rotatif. Un réfrigérant destiné à abaisser la température de l'air comprimé provenant du rotor de compresseur est fourni. L'air comprimé est mélangé avec un combustible et brûlé dans une chambre de combustion. Un palier de butée à feuilles destiné à supporter l'arbre rotatif comprend un collet de butée couplé à l'arbre rotatif ainsi qu'une paire de disques de butée situés à distance du collet de butée et fixés à un logement. Des joints pour rotor sont formés au niveau de deux surfaces du collet de butée et les aubes de turbine à action sont formées au niveau de la périphérie du collet de butée. Un générateur est positionné entre la butée de palier à feuille et le rotor du compresseur. Un partie de l'air froid provenant du refroidisseur est dérivée vers le générateur et les aubes de turbine à action.
