Description

  

  Pompe.    La présente invention se rapporte à une  pompe, caractérisée par deux cylindres con  tenant chacun un tambour pouvant tourner  autour de l'axe du cylindre et monté excen  triquement par rapport     à,    celui-ci de façon que  celle de ses génératrices correspondant au  rayon vecteur maximum soit toujours en con  tact avec la paroi du cylindre, un     coulisseau,     de longueur variable, étant disposé entre les  deux     excentriques    de façon à limiter, dans  chaque cylindre, avec la paroi de celui-ci et  celle du tambour, deux chambres, l'une<B>(le</B>  compression et l'autre d'aspiration.  



  Le dessin ci-annexé en représente, à titre       d'exemple,    une forme d'exécution.  



  La     fig.    1 en est une vue en coupe verti  cale axiale;       La,        fig.    2 en est nue coupe horizontale;  La     fig.    3 est une coupe     horizontale    par  tielle, et à plus grande échelle, d'une va  riante;  La     fig.    4 montre un détail de celle-ci.  Dans le carter 3     (fig.    1 et 2) sont pra  tiqués deux cylindres 1 et 2, de même dia  mètre et de même hauteur.

   Dans     chacun    de  ceux-ci est monté un tambour 12, respective  ment 13, pouvant tourner autour de l'axe    géométrique du cylindre, grâce aux touril  lons 17 respectivement 18, logés dans le carter,  et     disposé    excentriquement par rapport à cet  axe, ceci de façon telle que celle de ses géné  ratrices correspondant au rayon vecteur maxi  mum de l'excentrique soit en contact conti  nuel avec la paroi du cylindre correspondant.  La, base inférieure et supérieure de chaque  tambour forme un joint étanche avec le fond,  respectivement avec la base supérieure du cy  lindre correspondant, grâce aux anneaux du  segment d'étanchéité 14 et 15 montés dans le  tambour et poussés vers l'extérieur par les  ressorts 16.  



  Dans la paroi     séparant    les deux cylindres  est pratiquée une coulisse rectiligne dans la  quelle peut se déplacer un coulisseau formé  (le deux patins 23 et 24. Ces patins peuvent  glisser l'un par. rapport à l'autre suivant  l'axe longitudinal du coulisseau et des res  sorts 27 tendent à les éloigner constamment  l'un de l'autre de façon à donner au     coulis-          seau    sa longueur maximum.  



  Les canaux 4 et 5 communiquent avec  l'air libre, tandis que les canaux 6 et 7 com  muniquent par l'intermédiaire des soupapes  de retenue 8 et 9 avec un conduit 11 menant,      par exemple, à un réservoir d'air comprimé.  Le couvercle du carter 3 est formé de deux  parties superposées 21 et 22 limitant entre  elles une chambre remplie d'huile et conte  nant un train d'engrenages; ce     train,    est       fo:r@mé    par le pignon 20 fixé sur l'arbre moteur  et par les deux roues dentées 19 ayant le       même    nombre de dents et fixées sur les touril  lons supérieurs des tambours 12 et 13.  



  Le fonctionnement est le suivant: Comme  on le voit en     fig.    2, le coulisseau forme, dans  chaque cylindre, avec la paroi de celui-ci et       celle    du tambour correspondant, deux     charn-          f3res    31 et 32 qui, lorsque les tambours tour  nent dans le même sens, varient constamment  de volume; la chambre 31, qui     communique     avec l'air libre et dont le volume va gran  dissant pendant la durée d'un tour, constitue  une chambre d'aspiration, tandis que la  chambre     '02,    dont le volume va en dimi  nuant constitue une chambre de compression.

    Le coulisseau se déplace sous l'action des  tambours<B>12</B> et 13 et change de longueur  sous l'action de ses ressorts, de façon à se  trouver toujours appuyé par ses deux extré  mités contre la périphérie des tambours.  



  Dans la variante de     fig.    3 et     4,_    afin  d'obtenir un bon contact entre les extrémités  du coulisseau et la périphérie des tambours,  à l'action des ressorts 27 est ajoutée celle clé  l'air comprimé emprunté à la pompe. A cet  effet, clans chacun des patins 23, respective  ment 24, sont creusés trois cylindres dans  chacun desquels se meut un piston cylindri  que<B>26</B> contenant un ressort 27. Chacun des  cylindres du patin 24 est relié par un con  duit, de faible section, avec l'une des cham  bres de compression 32, tandis que chaque  cylindre du patin 23 est relié par un     conduis;     de faible section avec l'autre chambre de  compression 32.

   L'action de cet air comprimé  s'ajoute donc à celle des ressorts 27 pour ten  dre à allonger le coulisseau. 29 est une ca  vité centrale pratiquée dans ce dernier afin  de l'alléger et communiquant avec l'air par       IE    conduit 30. Pour changer la. vitesse     deq     tambours 12 et 13, il suffit de changer le  train d'engrenages contenu à l'intérieur clé la    chambre formée par les pièces 21 et 22. On  pourrait aussi supprimer les ressorts dans les  pistons.



  Pump. The present invention relates to a pump, characterized by two cylinders each containing a drum capable of rotating around the axis of the cylinder and mounted eccentrically with respect to the latter so that that of its generatrices corresponding to the maximum vector radius either always in contact with the wall of the cylinder, a slide, of variable length, being disposed between the two eccentrics so as to limit, in each cylinder, with the wall of the latter and that of the drum, two chambers, the one <B> (the </B> compression and the other suction.



  The accompanying drawing shows, by way of example, one embodiment.



  Fig. 1 is an axial vertical sectional view thereof; The, fig. 2 is a bare horizontal section; Fig. 3 is a horizontal section in part, and on a larger scale, of a variant; Fig. 4 shows a detail thereof. In the housing 3 (fig. 1 and 2), two cylinders 1 and 2, of the same diameter and the same height, are fitted.

   In each of these is mounted a drum 12, respectively 13, able to rotate around the geometric axis of the cylinder, thanks to the journals 17 respectively 18, housed in the housing, and disposed eccentrically with respect to this axis, this in such a way that that of its generators corresponding to the maximum vector radius of the eccentric is in continuous contact with the wall of the corresponding cylinder. The lower and upper base of each drum forms a sealed seal with the bottom, respectively with the upper base of the corresponding cylinder, thanks to the rings of the sealing segment 14 and 15 mounted in the drum and pushed outwards by the cylinders. springs 16.



  In the wall separating the two cylinders is formed a rectilinear slide in which a formed slide can move (the two pads 23 and 24. These pads can slide relative to one another along the longitudinal axis of the slide. and springs 27 tend to constantly move them away from each other so as to give the slide its maximum length.



  The channels 4 and 5 communicate with the free air, while the channels 6 and 7 communicate via the check valves 8 and 9 with a duct 11 leading, for example, to a compressed air tank. The housing cover 3 is formed of two superimposed parts 21 and 22 limiting between them an oil-filled chamber and containing a gear train; this train is formed by the pinion 20 fixed on the motor shaft and by the two toothed wheels 19 having the same number of teeth and fixed on the upper journals of the drums 12 and 13.



  The operation is as follows: As seen in fig. 2, the slide forms, in each cylinder, with the wall thereof and that of the corresponding drum, two hinges 31 and 32 which, when the drums turn in the same direction, constantly vary in volume; the chamber 31, which communicates with the free air and whose volume increases during the duration of one revolution, constitutes a suction chamber, while the chamber '02, whose volume decreases constitutes a chamber compression.

    The slide moves under the action of the drums <B> 12 </B> and 13 and changes length under the action of its springs, so that it is always supported by its two ends against the periphery of the drums.



  In the variant of fig. 3 and 4, _ in order to obtain good contact between the ends of the slide and the periphery of the drums, to the action of the springs 27 is added that of the compressed air taken from the pump. For this purpose, in each of the pads 23, respectively 24, are hollowed out three cylinders in each of which moves a cylindrical piston <B> 26 </B> containing a spring 27. Each of the cylinders of the pad 24 is connected by a duct, of small section, with one of the compression chambers 32, while each cylinder of the pad 23 is connected by a duct; of small section with the other compression chamber 32.

   The action of this compressed air is therefore added to that of the springs 27 in order to tend to lengthen the slide. 29 is a central cavity in the latter in order to lighten it and communicating with the air by IE duct 30. To change the. speed deq drums 12 and 13, it suffices to change the gear train contained within the key chamber formed by the parts 21 and 22. The springs in the pistons could also be eliminated.
