Pour fixer l'objet de l'invention d'une manière non limitative illustrée aux figures des dessins où :To fix the subject of the invention in a nonlimiting manner illustrated in the figures of the drawings where:
- La figure 1 est une vue en coupe longitudinale du moteur pneumatique selon l'invention.- Figure 1 is a longitudinal sectional view of the pneumatic motor according to the invention.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner in the figures of the drawings.
Le moteur pneumatique est constitué d'un arbre tourant (1) à très grande vitesse monté sur deux paliers (2) et entraînés en rotation sous l'effet d'un moins un jet d'air sortant sous pression et débit élevé sortant d'au moins un orifice ou bouche d'échappement ménagé radialement à un angle quelconque sur au moins un disque propulseur (3) solidaire de l'axe du moteur, ledit orifice débouchant sur le diamètre extérieur dudit disque propulseur.The pneumatic motor consists of a rotating shaft (1) at very high speed mounted on two bearings (2) and driven in rotation under the effect of at least one jet of air leaving under pressure and high flow leaving at least one orifice or exhaust outlet formed radially at any angle on at least one propellant disc (3) secured to the axis of the engine, said orifice opening onto the outside diameter of said propellant disc.
Plus précisémment, le moteur pneumatique comporte une ou plusieurs cages de réception d'un ou plusieurs disques propulseurs entraînés en rotation par au moins une injection d'un fluide sous pression, liquide ou gazeux.More precisely, the pneumatic motor comprises one or more cages for receiving one or more propulsion discs driven in rotation by at least one injection of a pressurized fluid, liquid or gaseous.
En se référant aux dessins, le moteur comprend un disque propulseur (3) agencé avec un alésage central (3-1) pour son montage sur l'axe du moteur.Referring to the drawings, the engine comprises a propellant disc (3) arranged with a central bore (3-1) for mounting on the axis of the engine.
Le disque comprend sur l'un de ses côtés un chambrage (3-2) constituant une chambre de réception du fluide sous pression.The disc comprises on one of its sides a recess (3-2) constituting a chamber for receiving the pressurized fluid.
Sur la périphérie du disque propulseur et dans son épaisseur sont réalisés un ou plusieurs conduits d'échappement (4) prenant naissance à leur extrémité (4-1) en étant en communication avec la chambre de réception, et débordant par leur autre extrémité (4-2) en constituant un conduit réactif sur tout ou partie de la largeur du disque propulseur et sur la périphérie extérieure de celui-ci en projetant le fluide dans la chambre intérieure de la cage d'échappement.On the periphery of the propellant disc and in its thickness are made one or more exhaust ducts (4) originating at their end (4-1) while being in communication with the receiving chamber, and overflowing at their other end (4-2) by constituting a reactive conduit over all or part of the width of the propellant disc and on the outer periphery thereof by projecting the fluid into the inner chamber of the exhaust cage.
La forme et le profil du ou des conduits d'échappement et réactif sont réalisés de la manière la plus appropriée pour le guidage et l'orientation du fluide, et la réalisation pratique.The shape and profile of the exhaust and reactant duct (s) are produced in the most appropriate manner for guiding and orienting the fluid, and for practical implementation.
Le disque propulseur est monté et fixé sur l'axe par tous moyens appropriés et en particulier par collage. De part et d'autre du disque propulseur sont disposés des flasques avant et arrière (5-6), destinés à étancher latéralement la chambre de réception du disque et le ou les conduits d'échappement du fluide tout en laissant libre le conduit réactif. Ces flasques réalisés en tous matériaux appropriés, d'épaisseur désirée, sont rapportés et fixés sur les faces latérales du disque et avantageusement par collage. Ils sont également fixés par collage par leur alésage intérieur (5-1) (6-1) sur l'axe du moteur.The propellant disc is mounted and fixed on the axis by any appropriate means and in particular by gluing. On either side of the propellant disk are disposed front and rear flanges (5-6), intended to seal laterally the disk receiving chamber and the fluid exhaust duct or ducts while leaving the reactive duct free. These flanges made of any suitable material, of desired thickness, are attached and fixed to the lateral faces of the disc and advantageously by gluing. They are also fixed by gluing by their internal bore (5-1) (6-1) on the axis of the motor.
L'ensemble ainsi constitué est monté à rotation dans la cage d'échappement (7). Celle -ci se présente sous la forme d'un manchon cylindrique avec une paroi formant fond (7-1) monté à position fixe sur les paliers (2). Une grille d'échappement (8) est rapportée et fixée sur la périphérie extérieure ou interne de la partie manchon de la cage de réception du disque propulseur. Cette grille est aménagée dans sa partie centrale avec une ouverture pour l'introduction d'une buse d'injection de fluide (9) montée en bout d'un tuyau d'alimentation du fluide. L'axe de la buse est en regard de l'extrémité de l'axe moteur. L'extrémité de ce dernier est conique et s'engage partiellement dans ladite buse pour éviter une déperdition du fluide. Pour assurer le guidage et l'introduction du fluide dans la chambre de réception du disque propulseur, il est prévu sur l'axe une gorge (10) constituant le conduit d'injection du fluide.The assembly thus formed is rotatably mounted in the exhaust cage (7). This is in the form of a cylindrical sleeve with a bottom wall (7-1) mounted in a fixed position on the bearings (2). An exhaust grille (8) is attached and fixed to the external or internal periphery of the sleeve part of the cage for receiving the propellant disc. This grid is arranged in its central part with an opening for the introduction of a fluid injection nozzle (9) mounted at the end of a fluid supply pipe. The axis of the nozzle is opposite the end of the motor axis. The end of the latter is conical and partially engages in said nozzle to avoid loss of the fluid. To guide and introduce the fluid into the receiving chamber of the propellant disc, it is provided on the axis a groove (10) constituting the fluid injection conduit.
Il est en outre prévu à l'arrière du moteur pneumatique ainsi conçu un nez ou bague d'arrêt (11) venant en appui sur les paliers.It is further provided at the rear of the pneumatic motor thus designed a nose or stop ring (11) coming to bear on the bearings.
Il convient de préciser le fonctionnement du moteur pneumatique. L'utilisateur envoie un fluide sous pression par la buse d'injection qui pénètre par l'intermédiaire du conduit d'injection réalisé sur l'axe du moteur dans la chambre de réception du disque propulseur.The operation of the air motor should be specified. The user sends a pressurized fluid through the injection nozzle which penetrates via the injection duct produced on the axis of the engine into the receiving chamber of the propellant disc.
Le fluide est alors évacué par le ou les conduits d'échappement disposés radialement sur le disque propulseur. Ce dernier est alors mis en rotation en entrainant l'axe du moteur auquel il est associé. Le fluide est projeté sur la périphérie interne de la cage d'échappement, puis il est évacué par les ouvertures ou évents de la grille d'échappement.The fluid is then discharged through the exhaust duct (s) arranged radially on the propellant disc. The latter is then rotated by driving the axis of the motor with which it is associated. The fluid is projected onto the internal periphery of the exhaust cage, then it is discharged through the openings or vents of the exhaust grille.
Selon les exprérimentations effectuées un tel moteur tourne à une vitesse qui peut être régulée par l'intensité de projection du fluide pour atteindre en toute fiabilité des vitesses entre 25 000 et 150 000 tours/minutes.According to the experiments carried out, such an engine rotates at a speed which can be regulated by the intensity of projection of the fluid in order to reliably reach speeds between 25,000 and 150,000 revolutions / minute.
Sans sortir du cadre de l'invention, le moteur pneumatique peut comprendre plusieurs disques propulseurs montés sur l'arbre lui conférant de multiples possibilités de couple. Par l'intermédiaire du conduit d'injection réalisé sur l'axe moteur, toutes les chambres de réception réalisées sur chaque disque seront à la même pression ainsi que les conduits d'échappement.Without departing from the scope of the invention, the pneumatic motor can comprise several propulsion discs mounted on the shaft giving it multiple possibilities of torque. Via the injection duct produced on the engine axis, all the reception chambers produced on each disc will be at the same pressure, as will the exhaust ducts.
Par ailleurs, le conduit d'échappement se prolongue pour former le conduit réactif, celui-ci étant réalisé sous la forme d'un trou, d'une fente, d'une rainure type rainure de clavette, de section appropriée au couple moteur désiré.Furthermore, the exhaust duct is extended to form the reactive duct, the latter being produced in the form of a hole, a slot, a keyway-like groove, of cross section suitable for the desired engine torque. .
Le moteur pneumatique selon l'invention trouve de très nombreuses applications.The pneumatic motor according to the invention finds numerous applications.
En particulier, ce moteur est particulièrement intéressant pour les turbines d'ébavurage et meulage, ou gravure ou perçage .In particular, this engine is particularly advantageous for deburring and grinding turbines, or engraving or drilling.
Les avantages ressortent bien de l'invention. En particulier, on souligne :The advantages emerge clearly from the invention. In particular, we emphasize:
- la simplicité de montage du moteur, évitant l'utilisation de toutes pièces de liaison.- the simplicity of mounting the motor, avoiding the use of any connecting parts.
