Description

       

   <Desc/Clms Page number 1> 
   pour :    "Pompe rotative". 



   La présente invention est relative à une pompe rotative com- prenant notamment un stator, dans lequel débouchent un canal d'ame- née et un canal d'évacuation de fluide, et un rotor, dont le mouve- ment de rotation s'effectue autour d'un axe fixe.. 



   Cette invention a pour but de réaliser une pompe d'une con- struction simple et robuste se composant d'un petit nombre de pièces constitutives ; le prix de revient en est d'ailleurs très faible. 



   A cet effet,,dans la pompe retative suivant l'invention, il est prévu au moins un alésage dans ledit rotor, perpendiculaire à l'axe fixe précité, tandis qu'un piston est monté dans ledit alésage et est commandé, lors de la rotation du rotor, par une bielle mon- tée sur un axe excentré par rapport à l'axe de rotation du rotor. 

 <Desc/Clms Page number 2> 

 



   Suivant une forme de réalisation particulièrement avantageuse de l'objet de l'invention, l'excentricité des axes précités est ré- glable par un déplacement de l'axe excentré susdit. 



   D'autres détails et particularités de l'invention ressorti- ront de la description d'une pompe rotative, donnée ci-après à titre d'exemple non limitatif avec référence aux dessins annexés. 



   La figure 1 représente une coupe transversale suivant I - I de la figure 2, d'une pompe rotative suivant l'invention. 



   La figure 2 est une coupe suivant II - II de la pompe rota- tive représentée à la figure 1. 



   Dahs les différentes figures, les mêmes signes de référence désignent des éléments identiques. 



   La pompe rotative suivant l'invention se compose essentielle- ment d'un corps de pompe ou stator 1 dans lequel débouche un canal d'amenée de fluide 2 ainsi qu'un canal d'évacuation de fluide 3. A l'intérieur de ce stator est monté un rotor   4   de forme cylindrique qui épouse la forme des parois cylindriques intérieures du stator 1. 



   Dans le rotor 4 est ménagé un alésage cylindrique 5 dont l'axe coupe perpendiculairement l'axe de rotation 6 du rotor ;    cet alésage est monté un piston 7 qui est commandé, lors de la rota-   tion du rotor 4, par une bielle 8 montée sur un axe 9 excentré par rapport à l'axe de rotation du rotor. Cette bielle est, d'autre part, fixée en 12 au piston 7. 



   Lors de la rotation du rotor, la chambre de compression 10, formée par la paroi inférieure 11 du piston 7, par une partie de l'alésage 5 et par une partie de la paroi cylindrique intérieure du stator 1, présente un volume variable. Ceci est dû à l'excentrici- té des axes 6 et   9.   Lors de la rotation au rotor dans le sens de la flèche, la chambre 10 se remplit d'abord de fluide, délivré par le canal d'amenée 2, puis, du fait de la réduction du volume de cette chambre, ce fluide est poussé vers le canal d'évacuation 3. 



   Le volume de fluide transporté lors d'un tour du canal 

 <Desc/Clms Page number 3> 

 d'amenée 2 vers le canal d'évacuation 3, peut être réglé.   A   cet effet, on prévoit des moyens pour changer la valeur de l'excentri- cité entre les deux axes 6 et 9. L'axe 9 est monté sur un chariot 13 qui peut se déplacer sur une glissière 14, solidaire du stator 1. 



   Le déplacement du chariot 13 peut être effectué au moyen d'une vis 15 qui entraîne ledit chariot. Ce déplacement peut être effectué lors de la rotation de la pompe. 



   Le déplacement peut, toutefois, également être commandé par un régulateur automatique. 



   Il doit être entendu que l'invention n'est nullement limitée à la forme de réalisation décrite ci-avant, et que bien des modifi- cations peuvent y être apportées, sans sortir du cadre de la pré- sente demande de brevet. 



   Dans la pompe suivant l'invention sont également prévus les organes habituels pour l'obtention de l'étanchéité nécessaire. 



   De plus, les parties rotatives seront calculées de façon à obtenir une pompe bien équilibrée. 



   REVENDICATIONS. 



   1. Pompe rotative comprenant notamment un stator, dans le- quel débouchent un canal d'amenée et un canal d'évacuation de flui- de, et un rotor, dont le mouvement de rotation s'effectue autour d'un axe fixe, caractérisée en ce qu'il est prévu au moins un alé- sage dans ledit rotor, perpendiculaire à l'axe fixe précité, tandis qu'un piston est monté dans ledit alésage et est commandé, lors de la rotation du rotor, par une bielle montée sur un axe excentré par rapport à l'axe de rotation du rotor.

   for: "Rotary pump".



   The present invention relates to a rotary pump comprising in particular a stator, into which open an inlet channel and a fluid discharge channel, and a rotor, the rotational movement of which takes place around it. of a fixed axis.



   The object of this invention is to provide a pump with a simple and robust construction consisting of a small number of constituent parts; the cost price is also very low.



   For this purpose, in the retative pump according to the invention, at least one bore is provided in said rotor, perpendicular to the aforementioned fixed axis, while a piston is mounted in said bore and is controlled, during the rotation of the rotor, by a connecting rod mounted on an axis eccentric with respect to the axis of rotation of the rotor.

 <Desc / Clms Page number 2>

 



   According to a particularly advantageous embodiment of the subject of the invention, the eccentricity of the aforementioned axes is adjustable by a displacement of the aforementioned eccentric axis.



   Other details and features of the invention will emerge from the description of a rotary pump, given below by way of non-limiting example with reference to the accompanying drawings.



   Figure 1 shows a cross section along I - I of Figure 2, of a rotary pump according to the invention.



   FIG. 2 is a section on II - II of the rotary pump shown in FIG. 1.



   In the different figures, the same reference signs designate identical elements.



   The rotary pump according to the invention consists essentially of a pump body or stator 1 into which opens a fluid supply channel 2 as well as a fluid discharge channel 3. Inside this. stator is mounted a rotor 4 of cylindrical shape which matches the shape of the inner cylindrical walls of stator 1.



   In the rotor 4 is formed a cylindrical bore 5 whose axis perpendicularly intersects the axis of rotation 6 of the rotor; this bore is fitted with a piston 7 which is controlled, during the rotation of the rotor 4, by a connecting rod 8 mounted on an axis 9 which is eccentric with respect to the axis of rotation of the rotor. This connecting rod is, on the other hand, fixed at 12 to the piston 7.



   During the rotation of the rotor, the compression chamber 10, formed by the lower wall 11 of the piston 7, by a part of the bore 5 and by a part of the internal cylindrical wall of the stator 1, has a variable volume. This is due to the eccentricity of the axes 6 and 9. When the rotor is rotated in the direction of the arrow, the chamber 10 firstly fills with fluid, delivered by the supply channel 2, then, due to the reduction in the volume of this chamber, this fluid is pushed towards the discharge channel 3.



   The volume of fluid transported during a tour of the canal

 <Desc / Clms Page number 3>

 inlet 2 to outlet channel 3, can be adjusted. For this purpose, means are provided for changing the value of the eccentricity between the two axes 6 and 9. The axis 9 is mounted on a carriage 13 which can move on a slide 14, integral with the stator 1.



   The movement of the carriage 13 can be effected by means of a screw 15 which drives said carriage. This movement can be carried out during the rotation of the pump.



   The displacement can, however, also be controlled by an automatic regulator.



   It should be understood that the invention is in no way limited to the embodiment described above, and that many modifications can be made thereto, without departing from the scope of the present patent application.



   In the pump according to the invention are also provided the usual members for obtaining the necessary sealing.



   In addition, the rotating parts will be calculated so as to obtain a well balanced pump.
