Abstract

L'invention concerne un moteur à combustion interne régénératif avec échangeur air-air, entraîné par plateau cyclique, avec un bloc-cylindres qu'on peut faire pivoter, qui comprend des cylindres de compression d'air (51) et des cylindres moteurs (63) qui sont disposés en anneau dans un bloc-cylindres (72) qu'on peut faire pivoter, les pistons de compression d'air (58) et les pistons moteurs (75) dans leurs cylindres respectifs étant reliés au plateau cyclique (35) disposé en oblique par un maillon de jonction correspondant, les cylindres secondaires (94) alimentant en gaz les cylindres de compression d'air et les cylindres moteurs, de sorte qu'on obtient une circulation régénérative avec refroidisseur intermédiaire efficace entre échangeur air-air (18) et régénérateur (28). En raison du fait que le bloc-cylindres qu'on peut faire pivoter forme un clapet à boisseau rotatif et à cause des différents évents disposés sur la croûte fixe, c'est toute la structure du moteur qui est simplifiée. Le moteur à combustion interne régénératif avec échangeur air-air englobe une variété de modes de réalisation et on peut l'utiliser comme groupe moteur pour une voiture, un véhicule commercial et un avion ou un bateau à hélice.
