Abstract

Dispositif de pompe (20), comprenant une tête de raccordement de pulvérisation (202) et une pompe à piston (10) ; la pompe à piston (10) comprend un ensemble pompe (100) et un ensemble va-et-vient (200) ; l'ensemble pompe (100) comprend un corps de pompe (110) et un piston (120) ; l'ensemble va-et-vient (200) comprend une source de puissance (210), un arbre de puissance (220) et un élément de va-et-vient (230) ; l'élément de va-et-vient (230) est en coopération de transmission avec l'arbre de puissance (220) ; le piston (120) est relié à l'élément de va-et-vient (230) ; lorsque la source de puissance (210) entraîne l'arbre de puissance (220) pour amener le piston (120) à effectuer un déplacement en va-et-vient dans une cavité volumétrique (111) au moyen de l'élément de va-et-vient (230), un fluide peut être aspiré dans la cavité volumétrique (111) à partir d'un premier canal (112) et évacué d'un second canal (113), ce qui permet d'obtenir un pompage du fluide ; des tiges de guidage (130) sont reliées au corps de pompe (110), un manchon de guidage (231) est formé sur une paroi externe de l'élément de va-et-vient (230), les tiges de guidage (130) sont agencées de manière à passer à l'intérieur du manchon de guidage (231), et la direction de la longueur des tiges de guidage (130) est cohérente avec la direction de déplacement de va-et-vient du piston (120). En outre, lorsque l'élément de va-et-vient (230) entraîne le déplacement du piston (120) en va-et-vient, en utilisant la coopération de guidage entre les tiges de guidage (130) et le manchon de guidage (231), la stabilité du piston (120) dans la direction de déplacement en va-et-vient peut être efficacement assurée, ce qui permet d'assurer la stabilité du pompage de fluide vers l'intérieur et vers l'extérieur.
