  • the inner body 16 moves to position as seen in FIG. 3 where the typical working chamber (third working chamber 58) is about cut off from the expansion port 72 by movement of third apex portion 48 at about the same time that the working chamber is opened to the exhaust port 74 by passage of the first apex portion 46 of the inner body.

Abstract

Moteurs rotatifs utilisant le cycle de Brayton. Le cycle des moteurs comprend les quatre temps d'aspiration, compression, expansion et échappement. Une version à cycle ouvert utilise de l'air comme fluide de travail primaire alors que des versions à cycle fermé (Fig. 7 et 10) utilisent de l'hélium en tant que fluide de travail. Chaque moteur comprend un corps externe (12) pourvu d'une cavité (14) et un corps interne (16) à l'intérieur de la cavité du corps externe (14) est monté de manière à pouvoir effectuer un mouvement relatif par rapport au corps externe (12). Quatre lumières (61, 62, 72 et 74) permettent l'accès à l'espace entre le corps interne et le corps externe. Ces lumières comprennent une lumière d'aspiration (61), une lumière de compression (62), une lumière d'expansion (72) et une lumière d'échappement (74). Une chambre d'absorption de chaleur (64) comprenant une source d'énergie thermique est en communication avec la lumière de compression (62) et la lumière d'expansion (72).
