Abstract

Selon l'invention, un moteur à air sous pression, en particulier pour des générateurs d'énergie électrique, comprend un rotor de moteur ayant deux brides intégrées à un arbre d'entraînement, ledit rotor comprenant en outre au moins une première chambre de pression et au moins une seconde chambre de pression pour équilibrer ledit rotor, ladite deuxième chambre de pression étant identique à ladite première chambre de pression et étant disposée symétriquement à l'opposé de la première chambre de pression, lesdites première et deuxième chambres étant alimentées en air sous pression, chaque chambre de pression étant conçue sous la forme d'un cylindre creux ou de tout autre type de corps creux, avec une surface fonctionnelle sur laquelle agit une pression générée par de l'air sous pression, ledit air sous pression entrant directement dans la première chambre et ensuite dans la deuxième chambre, ce qui permet d'obtenir un effet de levier amenant ledit rotor de moteur à tourner.
