CA 2181436

The proposed power unit of the rotary-piston type, for example and internal combustion engine, compressor or pump, has a stator and a rotor designed in such a way as to allow a number of variable-volume working chambers to be created in the stator when the rotor turns. The meshing mechanism between the stator and the rotary piston which rotates on an eccentric section of the shaft is essential for the management of that rotation and is situated outside the rotary piston. For that purpose an aperture is provided in the wall of the stator and is shut off by a rotating disk (or ring) through which a spigot passes and rigidly connects the rotary piston and a pinion. This arrangement creates a power unit with a triangular stator and a double-peak rotor. Several sets of balance, lamellate, spring-loaded sealing elements are mounted on the lateral surface of the stator. They are in contact with the side surface of the rotary piston which has a forced cooling system.

Le moteur de l'invention du type à piston rotatif, par exemple, un moteur à combustion interne, un compresseur ou une pompe, présente un stator (8) ainsi qu'un rotor (3) conçus de manière à permettre la création d'un certain nombre de chambres de travail à volume variable dans le stator lorsque le rotor tourne. Le mécanisme d'accouplement (13, 14) entre le stator et le piston rotatif tournant sur une partie excentrique (2) de l'arbre (1) est essentiel à la gestion de cette rotation, et se trouve à l'extérieur du piston rotatif. Pour ce faire, une ouverture (15) est ménagée dans la paroi (11) du stator et est fermée par un disque (ou bague) rotatif (16) à travers lequel un ergot (4) passe et relie solidairement le piston rotatif à un pignon (13). Cet agencement crée un moteur doté d'un stator triangulaire et d'un rotor à double sommet. Plusieurs ensembles d'éléments d'étanchéité lamellaires à ressorts sont montés sur la surface latérale du stator. Ils sont en contact avec la surface latérale (7) du piston rotatif doté d'un système de refroidissement forcé.
