Title
(EN) CYCLOID ROTOR ENGINE
(FR) MOTEUR À ROTOR CYCLOÏDE
Abstract
(EN) A rotary engine has a cycloid rotor and a sealing grid including a face seal that rotates with the rotor, and including other seals that do not rotate with the rotor. As the rotor rotates within a housing, the rotor, housing and seal grid form at least one working chamber between them, the chamber undergoing a change from initial volume V1 to V2, which is less than V1, thus compressing a working medium, and subsequently expanding to volume V3, which may be larger than V1, such that the chamber volume is a smooth and continuous function of rotor's rotational angle.
(FR) L'invention porte sur un moteur rotatif qui possède un rotor cycloïde et une grille d'étanchéité comprenant un joint d'étanchéité de face qui tourne avec le rotor, et d'autres joints d'étanchéité qui ne tournent pas avec le rotor. Lorsque le rotor tourne à l'intérieur d'un boîtier, le rotor, le boîtier et la grille d'étanchéité forment au moins une chambre de travail entre ceux-ci, la chambre subissant un changement d'un volume initial V1 à V2, qui est inférieur à V1, comprimant ainsi un milieu de travail, et se dilatant ultérieurement jusqu'au volume V3, qui peut être plus grand que V1, de telle sorte que le volume de la chambre est une fonction lisse et continue de l'angle de rotation du rotor.
