  • Figure 2 shows a radial sectional view of the rotary actuator device according to the invention.

Le dispositif selon l'invention permet d'une part, d'améliorer de façon considérable le rendement et le couple moteur disponible dès le commencement de l'alimentation du dispositif et d'autre part, de mettre en mouvement un très petit nombre de pièces qui assure un taux moyen avant panne (MTBF) excellent.The device according to the invention makes it possible, on the one hand, to considerably improve the efficiency and the engine torque available from the beginning of the power supply of the device and, on the other hand, to set in motion a very small number of parts. which ensures an excellent average failure rate (MTBF).

Lors de l'utilisation du dispositif selon l'invention en fonctionnement moteur, un fluide ou un gaz sous pression est injecté par au moins un orifice d'alimentation (4) d'un bloc cylindre (1). Ce gaz ou fluide passe par des canaux d'alimentation (14) aux travers du bloc cylindre (1), puis par des canaux traversant des flasques (17, 17') et enfin par des canaux traversant un piston (2) en forme de came.When using the device according to the invention in engine operation, a fluid or a gas under pressure is injected through at least one supply port (4) of a cylinder block (1). This gas or fluid passes through feed channels (14) through the cylinder block (1), then through channels flanges (17, 17 ') and finally through channels through a piston (2) in the form of cam.

Ce gaz ou fluide en fonction de sa pression détermine le couple moteur disponible. Le gaz ou fluide sous pression en rentrant dans une chambre (10), une fois son passage dans les canaux d'alimentation (14) du bloc cylindre (1) et dans les canaux traversant les flasques (17, 17'), exerce une poussée sur un tiroir séparateur (6) du bloc cylindre (1) ainsi que sur le piston (2). Ce piston (2), monté en rotation libre selon un axe ou arbre de transmission (3) et à l'intérieur du bloc cylindre (1), pivote autour de l'axe (3) en fonction du débit et de la pression du gaz ou fluide dans la chambre (10) du bloc cylindre (1) de façon à vider de son contenu une chambre d'échappement (11) du bloc cylindre (1) par un orifice (5) d'échappement. Afin de dépasser le point mort du dispositif fonctionnement en moteur, un volant cinétique (20) est disposé à une extrémité de l'arbre de transmission (3) et permet de stocker l'énergie cinétique.This gas or fluid as a function of its pressure determines the available engine torque. The gas or fluid under pressure entering a chamber (10), once its passage in the supply channels (14) of the cylinder block (1) and in the channels passing through the flanges (17, 17 '), exerts a pushing on a separator drawer (6) of the cylinder block (1) and on the piston (2). This piston (2), mounted in free rotation along an axis or transmission shaft (3) and inside the cylinder block (1), pivots about the axis (3) as a function of the flow rate and the pressure of the gas or fluid in the chamber (10) of the cylinder block (1) so as to empty its contents an exhaust chamber (11) of the cylinder block (1) by an orifice (5) exhaust. In order to exceed the dead point of the motor operating device, a kinetic flywheel (20) is disposed at one end of the transmission shaft (3) and makes it possible to store the kinetic energy.

Lors de l'utilisation du dispositif en fonctionnement compresseur ou pompe, l'entraînement du dispositif s'effectue de manière mécanique sur l'arbre de transmission (3). L'arbre de transmission (3) entraîne par un mouvement de rotation le piston (2). Lors de la rotation du piston (2), il se crée un effet d'aspiration au niveau de l'orifice d'alimentation (4) et durant le même cycle de fonctionnement du dispositif, le piston (2) refoule le gaz ou le liquide de façon à vider de son contenu la chambre d'échappement (11) par l'orifice d'échappement (5).When using the device in compressor or pump operation, the device is driven mechanically on the transmission shaft (3). The transmission shaft (3) rotates the piston (2). During the rotation of the piston (2), a suction effect is created at the supply orifice (4) and during the same operating cycle of the device, the piston (2) delivers the gas or the liquid to empty the exhaust chamber (11) from its contents through the exhaust port (5).

Le bloc cylindre (1) est doté d'un boîtier (19) composé lui-même du tiroir séparateur ou tirette (6), de deux ressorts (15), de trois segments (16) et d'une arrivée d'alimentation.The device comprises a rotary piston (2) for transforming a gaseous or liquid force into a mechanical force. This cam-shaped piston (2) is located inside the cylinder or cylinder block (1) of cylindrical shape and axis (3) and is rotatably connected to the transmission shaft (3) so as to pivot about said axis (3).

Entre ces deux segments (8, 9) est prévu le canal d'alimentation (12) du cylindre (1) sur un secteur défini selon la dimension et la forme du piston (2). Le canal d'alimentation (12) est réalisé sur un secteur de travail selon la courbure du piston (2) et d'un secteur tampon réalisé par un segment afin de stopper l'alimentation durant le temps mort de fonctionnement du dispositif. L'alimentation du dispositif est assurée par les canaux d'alimentation (14) du bloc cylindre (1) qui sont reliés à l'orifice d'alimentation (4) situé sur la surface extérieure du bloc cylindre (1). L'échappement est effectué lors de la rotation du piston (2) par les sorties latérales ou orifices d'échappement (5).Two flanges (17, 17 ') are provided on either side of the piston (2) to allow a maintenance of the entire axis (3) - piston (2). The two flanges (17, 17 ') comprise the space necessary to receive respectively two bearings in which the axis (3) is introduced and fixed so as to keep the piston (2) in rotation, the two bearings being maintained respectively by two small flasks or "flasks" (18, 18 ').
