Claims (9)

  1. Machine de pompage à diaphragme entraînée par voie hydraulique, en particulier pour pomper des matériaux difficiles à pomper, la pompe comprenant au moins un cylindre de pompe (5) qui a une première extrémité avec une première entrée et une première sortie (11) pour du fluide à pomper, et une seconde extrémité avec une seconde entrée et une seconde sortie (1) pour un fluide hydraulique, les entrées et les sorties étant associées à des valves respectives, un séparateur (6) situé à l'intérieur et mobile en va-et-vient le long du cylindre de pompe, le séparateur mobile (6) ayant un premier côté en face de la première extrémité du cylindre et un second côté en face de la seconde extrémité du cylindre, dans laquelle :
    - le séparateur mobile (6) est connecté vers l'intérieur de la première extrémité du cylindre par un premier diaphragme flexible (4) sous la forme d'un soufflet en accordéon qui est capable de se dilater et de se contracter à l'intérieur du cylindre (5) le long de la direction de la longueur du cylindre lorsque le séparateur mobile (6) se déplace en va-et-vient le long du cylindre, le premier côté du séparateur mobile délimitant une première chambre (c) à l'intérieur du diaphragme flexible capable de se dilater et de se contracter (4) pour contenir un volume variable de fluide pompé en communication avec la première entrée et la première sortie ;
    - le séparateur mobile (6) est connecté vers l'intérieur de la seconde extrémité du cylindre (5) par un second diaphragme flexible (10) sous la forme d'un soufflet en accordéon qui est capable de se contracter et de se dilater le long de la direction de la longueur du cylindre (5) en correspondance avec la dilatation et la contraction du premier diaphragme flexible (4), le second côté du séparateur mobile délimitant une seconde chambre (b) à l'intérieur du second diaphragme capable de se dilater et de se contracter (10) pour contenir un volume variable de fluide hydraulique en communication avec la seconde entrée et la seconde sortie ; et
    - un espace annulaire (a) est défini entre l'extérieur du premier et du second diaphragme (4, 10) et la paroi intérieure du cylindre de pompe (5), ledit espace annulaire (a) contenant en utilisation un fluide qui est le même que ledit fluide hydraulique ou qui a des caractéristiques hydrauliques similaires,
    caractérisée en ce que :
    le séparateur mobile (6) est sous la forme d'un plongeur qui est monté en coulissement dans la partie médiane de l'intérieur du cylindre (5) entre le premier et le second diaphragme (4, 10) en soufflet, une extrémité du plongeur (6) étant connectée au premier diaphragme (4) en soufflet, et l'autre extrémité du plongeur (6) étant connectée au second diaphragme (10) en soufflet pour définir un premier et un second espace annulaire (a) respectif, à savoir un premier espace annulaire (a) entre l'extérieur du premier diaphragme (4) en soufflet et la paroi intérieure du cylindre de pompe (5) et un second espace annulaire (a) entre l'extérieur du second diaphragme (10) en soufflet et la paroi intérieure du cylindre de pompe (5), dans laquelle le premier et le second espace annulaire (a) sont indépendants l'un de l'autre et la pression du fluide dans le premier espace annulaire (a) est indépendante de la pression du fluide dans le second espace annulaire (a).
  2. Machine selon la revendication 1, dans laquelle le plongeur (6) est monté en coulissement dans un élément d'étanchement (7) fixé à l'intérieur d'une partie médiane de l'intérieur du cylindre (5).
  3. Machine selon la revendication 1 ou 2, dans laquelle le diamètre extérieur du plongeur (6) correspond au diamètre moyen du premier et du second diaphragme (4, 10) en soufflet.
  4. Machine selon la revendication 1, 2 ou 3, dans laquelle pendant le fonctionnement le volume du premier et du second espace (a) reste essentiellement constant.
  5. Machine selon l'une quelconque des revendications précédentes, comprenant des moyens pour commuter automatiquement une valve (102) destinée à commander l'alimentation de fluide hydraulique vers le cylindre hydraulique à des moments donnés du cycle de la machine, dans laquelle lesdits moyens pour commuter la valve comprennent un commutateur hydromécanique comprenant :
    - une tringlerie (108, 109) pour convertir un mouvement linéaire de ladite pièce de machine (106) en un mouvement rotatif ;
    - une came (103) entraînée en rotation par ladite tringlerie (105, 109) ; et
    - un ressort (115) agencé pour être comprimé et stocker de l'énergie par rotation de la came (103) pendant une course de ladite pièce de machine (106), et agencé pour dégager son énergie stockée et commuter ladite valve (102) pour commander l'alimentation de fluide hydraulique vers le cylindre hydraulique (107) de la machine quand ladite pièce (106) est située à des positions données le long du cylindre hydraulique (107), c'est-à-dire pour commander le cycle de travail de la machine.
  6. Machine selon la revendication 5, dans laquelle le ressort (115) est un ressort de compression monté sur un bras (150) s'étendant depuis la came (103) de telle façon que lors d'un entraînement en rotation de la came (103) par la tringlerie (108, 109) l'extrémité du ressort adjacent à came est comprimée jusqu'à ce que le ressort atteigne un point d'équilibre instable "A" au-delà duquel le ressort dégage son énergie stockée pour commuter ladite valve (102).
  7. Machine selon la revendication 5 ou 6, dans laquelle quand le ressort dégage son énergie stockée, il entraîne en premier de manière abrupte la came (103) et, après que la came ait tourné d'un angle donné, la came (103) fait tourner une pièce pour commuter la valve (102).
  8. Machine selon la revendication 5, 6 ou 7, dans laquelle ladite tringlerie (109) est agencée pour faire tourner la came sur un angle plus petit que 180° pour chaque course de ladite pièce de machine (106).
  9. Machine selon l'une quelconque des revendications 5 à 8, dans laquelle la tringlerie (108, 109) est une tringlerie à vis-et-écrou comprenant un écrou (108) et une tige filetée (109).
