Abstract

Titre : Pompe comprenant un piston à course variable L’invention concerne pompe (1) comprenant :- un corps de pompe (300) ;- un piston (600) mobile en translation dans le corps de pompe (300), selon un axe de translation (X) ;- des moyens moteurs (101) pour entraîner en translation le piston (600) dans le corps de pompe (300) ;- des moyens de réglage de la course du piston (600),caractérisée en ce que les moyens de réglage de la course du piston (600) comprennent :- un capteur de fin de course (700) du piston (600) ;- un calculateur (701) relié au capteur de fin de course (700) et aux moyens moteurs (101),le calculateur (701) étant paramétré pour générer et transmettre une consigne de fonctionnement aux moyens moteurs (101), à partir d’un signal de sortie du capteur de fin de course (700), et pour ajuster la course du piston (600) dans le corps de pompe (300) selon une course nominale prédéfinie. Figure pour l’abrégé : Fig. 3Title: Pump comprising a piston with variable stroke The invention relates to a pump (1) comprising:- a pump body (300);- a piston (600) movable in translation in the pump body (300), along an axis of translation (X);- motor means (101) for driving the piston (600) in translation in the pump body (300);- means for adjusting the stroke of the piston (600), characterized in that the means for adjusting the stroke of the piston (600) comprise:- an end-of-stroke sensor (700) of the piston (600);- a computer (701) connected to the end-of-stroke sensor (700) and to the motor means (101 ), the computer (701) being configured to generate and transmit an operating instruction to the motor means (101), from an output signal from the end-of-travel sensor (700), and to adjust the stroke of the piston ( 600) in the pump body (300) according to a predefined nominal stroke.
