Abstract

Cette invention se rapporte à une pompe à palettes comportant un arbre central conçu pour être mis en rotation par une force extérieure, une couronne de train planétaire formée dans la partie creuse ménagée dans l'arbre, un engrenage linéaire formé au niveau d'une extrémité d'un organe de couplage à vitesse constante et engrené avec la couronne de train planétaire, et une couronne de train planétaire formée dans la partie creuse d'un rotor interne et engrenée avec l'engrenage linéaire formé au niveau de l'autre extrémité de l'organe de couplage à vitesse constante. Cet agencement permet de mettre en rotation l'arbre et le moteur interne à une même vitesse, d'insérer une partie circulaire formée au niveau d'une extrémité de palette à l'intérieur d'un espace creux circulaire du rotor interne, d'amener l'autre extrémité de la palette en contact avec une surface interne d'un rotor externe, et de faire varier le volume d'une chambre de compression et celui d'une chambre d'alimentation, l'air étant ainsi comprimé, ce qui permet à cette pompe à palettes de faible volume de produire de l'air comprimé à haute pression sans provoquer la collision de pièces susceptible de générer du bruit.
