  • first and second parts of the movement of said movable part relative to the chamber are distinct from each other, that is to say that the positions respectively adopted by the movable part on the first part of the movement are all different from the positions respectively adopted by the moving part on the second part of the movement.
  • the first upstream circular lip allows a passage of free fluid between said first space and said suction inlet, it induces a limited pressure loss during operation. fluid admission to the chamber.
  • the pump according to the invention can operate without such a valve at the inlet.
  • the efficiency of the pump is thus improved during its fluid admission phase to the chamber.
  • the pump according to the invention is thus particularly effective for transferring a fluid which can be a gas or a liquid.
  • the pump 100 comprises a suction inlet 41 and a discharge outlet 42.
  • This pump includes a motor 46 located either outside the chamber 44 as on the figure 1a , either inside the room as on the figures 2 to 4 .
  • this motor 46 is mechanically connected to the moving part to be able to move it in the chamber 44.
  • the pump 100 also includes a first upstream lip 120a placed closer to the suction inlet 41 than to the discharge outlet 42 and a first downstream lip 121a placed closer to the discharge outlet 42 than to the discharge outlet 42. suction inlet 41.

  • the probe 50 can be adjustable so as to adjust a detection level from which the probe detects the presence of liquid on a floor where the pump is placed.
  • the probe 50 may comprise at least two electrodes 51 spaced from one another to be able to detect the reaching of a liquid level based on a measurement of at least one electrical characteristic carried out with these electrodes. This electrical characteristic must be variable depending on the nature of the fluid located between these electrodes.
  • this electrical characteristic measured using these electrodes can be an electrical resistance between these electrodes, a current intensity between these electrodes, an electrical voltage between these electrodes.
  • the control unit UC can, based on this measurement, control the activation of the electric motor 46.

Pumpe nach einem der Ansprüche 1 bis 11, bei der der Motor (46) mit dem beweglichen Teil (45) über einen Kopplungsmechanismus (52) derart verbunden ist, dass die Betätigung des Motors (46) eine Hin- und Herbewegung des beweglichen Teils (45) in Bezug auf die Kammer induziert, um ein Fluid von dem Saugeinlass in Richtung des Förderauslasses zu bewegen.
  15. Pumpe nach Anspruch 14, bei der die Hin- und Herbewegung des beweglichen Teils (45) eine axiale Bewegung entlang einer zentralen Symmetrieachse des beweglichen Teils (45) ist, das die Form eines Rotationskörpers hat.
  16. Pumpe nach Anspruch 14, bei der die Hin- und Herbewegung des beweglichen Teils (45) eine radiale Bewegung um eine zentrale Symmetrieachse des beweglichen Teils ist, das rohrförmig ist.
  17. Pumpe nach einem der Ansprüche 1 bis 16, bei der der genannte Motor ein Elektromotor ist, der sich außerhalb der Kammer (44) befindet.
  18. Pumpe nach einem der Ansprüche 1 bis 16, bei der der genannte Motor ein Elektromotor ist, der sich im Inneren der Kammer (44) befindet.
  19. Pumpe nach einem der Ansprüche 1 bis 18, bei der der Motor mit einer Steuereinheit (UC) verbunden ist, wobei diese Steuereinheit ausgebildet ist, den Betrieb des Motors (46) in Abhängigkeit von mindestens einem Wert zu regeln, der zuvor von der Steuereinheit geschätzt wurde.
  20. Pumpe nach einem der Ansprüche 1 bis 19, bei der die Pumpe eine zweite Wand (44b) der Kammer (44) umfasst, wobei das Teil (44) zwischen der ersten und der zweiten Wand (44a, 44b) der Kammer (45) unter der Wirkung des genannten mindestens einen Motors (46) beweglich ist, wobei die Pumpe (100) ferner eine zweite stromaufwärtige Lippe (120b) umfasst, die näher zum Saugeinlass (41) als zum Förderauslass (42) angeordnet ist, sowie eine zweite stromabwärtige Lippe (121b), die näher zum Förderauslass (42) als zum Saugeinlass (41) angeordnet ist, wobei diese zweite stromaufwärtige und diese zweite stromabwärtige Lippe (120b, 121b) zwischen einer der Seiten des genannten beweglichen Teils (45) und der genannten zweiten Wand (44b) der Kammer (44) angeordnet sind, um einen zweiten Raum (123b) zwischen dieser zweiten stromaufwärtigen und dieser zweiten stromabwärtigen Lippe (120b, 121b) zu definieren, wobei diese zweite stromaufwärtige und diese zweite stromabwärtige Lippe (120b, 121b) derart sind, dass:
    - auf einem dritten Abschnitt der genannten Bewegung des genannten beweglichen Teils (45) in Bezug auf die Kammer (44) die zweite stromabwärtige Lippe (121b) eine Abdichtung erzeugt, die dem Fluiddurchtritt von der genannten Förderauslass (42) in Richtung des genannten ersten Raums (123a) verhindert, wobei die zweite stromaufwärtige Lippe (120b) dann einen freien Fluiddurchtritt zwischen dem genannten zweiten Raum (123b) und dem genannten Saugeinlass (41) gestattet; und dass
    - auf einem vierten Abschnitt der genannten Hin- und Herbewegung des genannten beweglichen Teils (45) in Bezug auf die Kammer (44), der von dem dritten Abschnitt der Bewegung verschieden ist, die zweite stromaufwärtige Lippe (120b) eine Abdichtung erzeugt, die den Fluiddurchtritt von dem genannten zweiten Raum (123b) in Richtung des genannten Saugeinlasses (41) verhindert, wobei die zweite stromabwärtige Lippe (121b) so ausgebildet ist, dass sie während der gesamten Bewegung des genannten beweglichen Teils (45) in Bezug auf die Kammer (44):
    - den Fluiddurchtritt von dem zweiten Raum (123b) in Richtung des genannten Förderauslasses (42) gestattet; und
    - den Fluiddurchtritt von dem genannten Förderauslass (42) in Richtung des genannten zweiten Raums (123a) verhindert.
  21. Pumpe nach einem der Ansprüche 1 bis 20, wobei diese Pumpe (4) trocken-selbstansaugend ist.
  22. Pumpe nach einem der vorhergehenden Ansprüche, bei der jede der genannten Lippen eine kreisförmige Lippe ist.
