Description

  

  Pompe rotative réversible.    L'invention a pour objet une pompe rota  tive réversible comportant un rotor cylin  drique pourvu de palettes de propulsion  mobiles et monté dans un corps de pompe  de manière à ce qu'il soit tangent à la paroi  interne, entre une lumière d'admission et une  lumière d'échappement dudit corps de pompe,  les palettes étant ajustées et mobiles chacune  dans un logement du rotor de façon que leurs  extrémités extérieures soient toujours en con  tact avec ladite paroi comprenant, entre la  lumière d'admission et la lumière d'échappe  ment, une partie concentrique à la surface  cylindrique du rotor et constituant, conjoin  tement avec cette dernière, une chambre de  travail que parcourent les palettes du rotor  et dont la section transversale est constante,

    les palettes étant percées de part en part  pour permettre au fluide aspiré et à propul  ser de pénétrer au fond du logement des  palettes.  



  La pompe est caractérisée selon l'inven  tion en ce que le rotor comprend des renfle  ments latéraux symétriques en forme de cônes    dont l'axe coïncide avec l'axe de rotation du  rotor, et en ce qu'il est percé de part en  part d'ouvertures radiales servant de loge  ments aux palettes de propulsion, l'arbre du  rotor constituant la fermeture interne     des-          dites    ouvertures et servant d'appui aux res  sorts de rappel des palettes de propulsion.  



  Le dessin ci-joint montre, à titre d'exem  ple, une forme d'exécution de l'objet de l'in  vention.  



  La     fig.    1 la représente en coupe trans  versale, suivant la ligne     I-I    de la     fig.    2 ;  La     fig.    2 en est une coupe longitudinale  suivant la ligne     II-II    de la     fig.    1 ;  La     fig.3    montre en élévation, à plus  petite échelle, le rotor de la pompe.  



  La pompe représentée comprend un corps  de pompe constitué par un bâti annulaire 4,  deux     coussinets    5 et deux écrous 6. Les  coussinets 5 s'appuient latéralement contre  une collerette interne 7 du bâti et sont fixés  au moyen des écrous 6. Entre les coussinets  5 est ajusté le rotor cylindrique 8 claveté      sur l'arbre 9 monté sur deux paliers à ai  guilles 10 fixés dans les coussinets 5.  



  Le rotor présente deux joues 11 formées  par des renflements latéraux symétriques en  forme de cônes du rotor et dont l'axe coïn  cide avec l'axe de rotation de l'arbre 9. Les  joues coniques II sont emboîtées dans les  coussinets 5 de forme correspondante et con  fèrent au rotor la forme d'un corps de révo  lution dont la matière est plutôt concentrée  vers l'axe de     rotation    du rotor, ce qui per  met de donner à ce dernier un diamètre re  lativement petit et     offre    l'avantage de main  tenir     l'effet    de la force centrifuge du rotor  dans une limite restreinte.  



  La partie cylindrique du rotor est percée  de part en part d'ouvertures radiales 12 ayant  une section transversale rectangulaire et dont  l'arbre 9 du rotor constitue la fermeture in  terne. Dans chacune de ces ouvertures 12  est ajustée et peut glisser une palette de  propulsion 13 percée de part en part, de  l'extérieur vers l'intérieur, d'un canal 14.  Entre chaque palette 13 et l'arbre 9 est  disposé un ressort de rappel 15 tendant tou  jours à pousser la palette hors de son loge  ment, contre la surface interne de la colle  rette 7. La surface cylindrique du rotor est  tangente en 16 à la paroi interne de la col  lerette 7, entre une lumière d'admission 17  et une lumière d'échappement 18 ménagées  dans le bâti 4 du corps de pompe.

   Ladite  paroi interne présente une partie cylindrique  19 qui est concentrique à la surface cylin  drique du rotor et constitue, conjointement  avec celle-ci et les coussinets 5, une chambre  de travail semi-circulaire 20 concentrique à  l'axe de rotation du rotor. Cette chambre  communique, d'une part, avec la lumière  d'admission 17 et, d'autre part, avec la lu  mière d'échappement<B>18;</B> sa section transver  sale est constante sur toute son étendue an  gulaire limitée par lesdites lumières.  



  La pompe décrite fonctionne comme une  pompe aspirante et foulante. A supposer que  le rotor soit animé d'un mouvement de ro  tation suivant le sens indiqué par la     flèche       en     fig.    1, les palettes 13 parcourent l'une  après l'autre la chambre de travail 20 en  aspirant du fluide par la lumière 17 et en  le refoulant par la lumière 18. En passant  devant la lumière d'aspiration, chaque palette  aspire par sa face postérieure et refoule par  sa face antérieure.

   Le fluide aspiré pénètre  alors dans le canal 14 de la palette et dans  le fond du logement 12, établissant ainsi  l'équilibre de pression sur les extrémités exté  rieure et intérieure de la palette, de sorte  que celle-ci peut se mouvoir librement dans  son logement sous l'action de son ressort de  rappel et se maintenir en contact avec la  paroi extérieure de la chambre de travail 20.  Il en est de même lorsque les palettes refou  lent le fluide par la lumière d'échappement  18 car, aussitôt que le canal 14 de la pa  lette entre en' communication avec la lumière  18, l'équilibre de pression s'établit entre les  extrémités extérieure et intérieure de la pa  lette et rend inopérante, sur le libre jeu de  la palette, la force de réaction du fluide re  foulé.

      Le fonctionnement de la pompe est ré  versible car, en inversant le sens de rotation  du rotor, les palettes aspirent le fluide par  la lumière 18 et le refoulent par la lumière  17. La pompe peut encore être utilisée comme  machine motrice si elle est alimentée par un  fluide sous pression amené par l'une ou l'autre  des lumières 17 et 18.  



  La pompe selon la construction décrite  offre la possibilité de munir son rotor d'un  grand nombre de palettes et de réaliser ainsi  une machine à la fois puissante, peu encom  brante, d'un degré de rendement élevé et  fort robuste, les     résistances    passives résul  tant de la force centrifuge et de la dilata  tion des organes mobiles étant réduites au  minimum grâce à la conception constructive  et à la disposition du rotor.  



  En raison de tous ces avantages, la pompe  selon l'invention se prête à de nombreuses  applications pratiques dans l'industrie, en  particulier dans le domaine des mécanismes  de changement de vitesse à fluide.



  Reversible rotary pump. The invention relates to a reversible rotary pump comprising a cylindrical rotor provided with movable propulsion vanes and mounted in a pump body so that it is tangent to the internal wall, between an inlet port and an exhaust port of said pump body, the vanes each being adjusted and movable in a housing of the rotor so that their outer ends are always in contact with said wall comprising, between the inlet port and the exhaust port ment, a part concentric with the cylindrical surface of the rotor and constituting, together with the latter, a working chamber through which the rotor vanes travel and whose cross section is constant,

    the vanes being pierced right through to allow the fluid sucked and propelled to penetrate to the bottom of the housing of the vanes.



  The pump is characterized according to the invention in that the rotor comprises symmetrical lateral bulges in the form of cones, the axis of which coincides with the axis of rotation of the rotor, and in that it is drilled right through. radial openings serving as housings for the propulsion vanes, the rotor shaft constituting the internal closure of said openings and serving as a support for the return springs of the propulsion vanes.



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



  Fig. 1 shows it in transverse section, along line I-I of FIG. 2; Fig. 2 is a longitudinal section along the line II-II of FIG. 1; Fig. 3 shows in elevation, on a smaller scale, the pump rotor.



  The pump shown comprises a pump body consisting of an annular frame 4, two bearings 5 and two nuts 6. The bearings 5 bear laterally against an internal flange 7 of the frame and are fixed by means of the nuts 6. Between the bearings 5 is fitted the cylindrical rotor 8 keyed on the shaft 9 mounted on two needle bearings 10 fixed in the bearings 5.



  The rotor has two cheeks 11 formed by symmetrical lateral bulges in the form of cones of the rotor and the axis of which coincides with the axis of rotation of the shaft 9. The conical cheeks II are fitted into the bearings 5 of corresponding shape. and give the rotor the shape of a revolving body whose material is rather concentrated towards the axis of rotation of the rotor, which makes it possible to give the latter a relatively small diameter and offers the advantage of hand keep the effect of the centrifugal force of the rotor to a limited extent.



  The cylindrical part of the rotor is pierced right through with radial openings 12 having a rectangular cross section and of which the rotor shaft 9 constitutes the internal closure. In each of these openings 12 is adjusted and can slide a propulsion vane 13 pierced right through, from the outside to the inside, with a channel 14. Between each vane 13 and the shaft 9 is arranged a spring. return 15 always tending to push the pallet out of its housing, against the internal surface of the glue rette 7. The cylindrical surface of the rotor is tangent at 16 to the internal wall of the collar 7, between a slot intake 17 and an exhaust port 18 formed in the frame 4 of the pump body.

   Said inner wall has a cylindrical part 19 which is concentric with the cylindrical surface of the rotor and together with this and the bearings 5 constitutes a semicircular working chamber 20 concentric with the axis of rotation of the rotor. This chamber communicates, on the one hand, with the intake port 17 and, on the other hand, with the exhaust light <B> 18; </B> its transverse cross section is constant over its entire extent. gulaire limited by said lights.



  The pump described functions as a suction and pressure pump. Assuming that the rotor is driven by a rotational movement in the direction indicated by the arrow in fig. 1, the paddles 13 pass through the working chamber 20 one after the other, sucking fluid through the port 17 and pushing it back through the port 18. Passing in front of the suction port, each paddle sucks through its face. posterior and pushes back through its anterior surface.

   The sucked fluid then enters the channel 14 of the pallet and the bottom of the housing 12, thus establishing the pressure balance on the outer and inner ends of the pallet, so that the latter can move freely in its housing under the action of its return spring and keep in contact with the outer wall of the working chamber 20. It is the same when the vanes return the fluid through the exhaust port 18 because, as soon as the channel 14 of the pallet enters into communication with the lumen 18, the pressure balance is established between the outer and inner ends of the pallet and renders inoperative, on the free play of the pallet, the reaction force of the pallet. fluid re fouled.

      The operation of the pump is reversible because, by reversing the direction of rotation of the rotor, the vanes suck the fluid through the port 18 and discharge it through the port 17. The pump can still be used as a driving machine if it is powered by a pressurized fluid supplied by one or the other of the ports 17 and 18.



  The pump according to the construction described offers the possibility of providing its rotor with a large number of vanes and thus producing a machine that is both powerful, compact, of a high degree of efficiency and very robust, the passive resistances resulting from the both the centrifugal force and the expansion of the moving parts being reduced to a minimum thanks to the constructive design and the arrangement of the rotor.



  By virtue of all these advantages, the pump according to the invention lends itself to numerous practical applications in industry, in particular in the field of fluid speed change mechanisms.
