Description

  

  Pompe à piston, pour soins     hygiéniques    et médicaux.    La présente invention se rapporte à une  pompe à piston, pour soins hygiéniques et  médicaux; celle-ci est caractérisée en ce que  son piston est soumis à l'action d'un ressort  qui tend toujours à l'amener en fond de  course de compression et en ce qu'elle pré  sente un verrou qu'un ressort engage avec le  piston, lorsque celui-ci est à fond de course  d'aspiration, pour le maintenir dans cette  position, le tout de façon qu'il suffise de dé  placer le verrou à l'encontre de son ressort  pour que le piston, sous l'action de son ressort,  effectue sa course de compression.  



  De préférence, le déplacement du verrou  à l'encontre de son ressort, pour le dégage  ment du piston, se fera par l'intermédiaire  d'un levier porté par le corps de pompe, ce  qui diminuera     l'effort    à exercer pour obtenir  ce dégagement.  



  Le dessin ' ci-annexé représente, à titre  d'exemple et en coupe axiale, une forme  d'exécution de l'objet de l'invention.  



  Le cylindre de la pompe     réprésentée     comprend un manchon a auquel sont fixés,  par des pas de vis, un fond al et un chapeau  a2. Dans ce cylindre se meut un piston     b       formé d'un corps     bi    et d'une tige     b2    terminée  par un anneau de     manoeuvre        bg.    Ce piston  est constamment soumis à l'action d'un ressort  hélicoïdal c logé dans le chapeau et qui tend  à amener le piston à fond de course de com  pression. Sur le chapeau a2 est monté un  verrou d destiné à pénétrer dans l'ouverture  horizontale b4 de la tige b2 lorsque le piston  est à fond de course d'aspiration, comme  représenté au dessin.

   Un ressort hélicoïdal     dr     tend constamment à déplacer le verrou d de  droite à gauche à la figure. A son extrémité  de droite, ce verrou est articulé à l'extrémité  supérieure d'un levier e monté     rotativement     sur le chapeau en     ei.     



       Pour    utiliser la pompe, on la remplit du  liquide à injecter en déplaçant le piston à  fond de course d'aspiration comme représenté  à la figure. Dans cette position, le verrou d  pénètre     automatiquement-    dans l'ouverture b4  et maintient le piston dans la position repré  sentée. Pour injecter le liquide, on introduit  la tubulure f de la pompe, dans la cavité à  laver et on agit sur l'extrémité inférieure du  levier e de façon à déplacer le verrou d de  gauche à droite, à l'encontre du ressort di,      jusqu'à ce qu'il abandonne la cavité     b4.    Le  piston est alors libéré et son ressort c l'amène  à fond de course de compression.

   Pendant  ce mouvement, il est guidé par l'extrémité  gauche du verrou d qui est restée engagée  dans la rainure verticale     b,5    de la tige     ba.     



  Dans le fond     ai,    à côté de la tubulure  d'injection f, est disposée une petite tubulure  fi par laquelle on pourra aspirer le liquide  à injecter dans le cylindre a. Dans ce cas,  les deux tubulures     fi    et f seront munies,  chacune, d'une soupape s'ouvrant à l'aspira  tion et se fermant à la compression, et la  deuxième d'une soupape fonctionnant en sens  contraire.



  Piston pump, for hygienic and medical care. The present invention relates to a piston pump, for hygienic and medical care; this is characterized in that its piston is subjected to the action of a spring which always tends to bring it to the bottom of the compression stroke and in that it presents a latch that a spring engages with the piston, when the latter is at the bottom of the suction stroke, to keep it in this position, all so that it is sufficient to move the lock against its spring so that the piston, under the action of its spring, performs its compression stroke.



  Preferably, the movement of the lock against its spring, for the release of the piston, will be done by means of a lever carried by the pump body, which will reduce the force to be exerted to obtain this clearance.



  The accompanying drawing represents, by way of example and in axial section, an embodiment of the object of the invention.



  The cylinder of the pump shown comprises a sleeve a to which are fixed, by threads, a bottom a1 and a cap a2. In this cylinder moves a piston b formed by a body bi and a rod b2 terminated by an operating ring bg. This piston is constantly subjected to the action of a coil spring c housed in the cap and which tends to bring the piston to the full compression stroke. On the cap a2 is mounted a lock d intended to penetrate into the horizontal opening b4 of the rod b2 when the piston is at the bottom of the suction stroke, as shown in the drawing.

   A coil spring dr constantly tends to move the latch d from right to left in the figure. At its right end, this lock is articulated to the upper end of a lever e mounted rotatably on the cap ei.



       To use the pump, it is filled with the liquid to be injected by moving the piston to the end of the suction stroke as shown in the figure. In this position, the latch d automatically enters the opening b4 and maintains the piston in the position shown. To inject the liquid, the tubing f of the pump is introduced into the cavity to be washed and one acts on the lower end of the lever e so as to move the lock d from left to right, against the spring di, until it leaves cavity b4. The piston is then released and its spring c brings it to the full compression stroke.

   During this movement, it is guided by the left end of the latch d which has remained engaged in the vertical groove b, 5 of the rod ba.



  In the bottom ai, next to the injection pipe f, is arranged a small pipe fi through which we can suck the liquid to be injected into the cylinder a. In this case, the two pipes fi and f will each be provided with a valve opening on suction and closing on compression, and the second with a valve operating in the opposite direction.

SOUS-REVENDICATION Pompe à piston selon la revendication, caractérisée en ce que le déplacement du verrou à l'encontre de son ressort s'effectue par l'intermédiaire d'un levier porté par le corps de la pompe. CLAIM Piston pump, for hygienic and medical care, characterized in that the piston is subjected to the action of a spring which always tends to bring it to the bottom of the compression stroke and in that it has a lock which '' a spring engages with the piston, when the latter is at the bottom of the suction stroke to keep it in this position, all so that it is sufficient to move the lock against its spring for the piston , under the action of its spring, performs its compression stroke. SUB-CLAIM Piston pump according to claim, characterized in that the movement of the lock against its spring is effected by means of a lever carried by the body of the pump.
