Abstract

Distributeur de seringue du type à gâchette dans lequel, bien qu'elle soit construite de manière à ce qu'un piston soit poussé vers le bas par une structure à gâchette, la buse ne bouge pas et, de plus, le distributeur présente une structure simple. Le distributeur de seringue du type à gâchette comprend un bouchon (4) fixé à une section bouche d'un corps (7) de conteneur; un corps (1) de base comportant un cylindre (11) en contact avec le bouchon et comportant encore un élément (12) couvercle; le piston (23) pouvant coulissant dans le cylindre; et la structure (3) de gâchette pour faire coulisser le piston de haut en bas. Un mouvement de pivot de la structure de gâchette fait coulisser le piston de haut en bas pour éjecter le liquide dans le cylindre depuis la section (21) buse vers l'extérieur. La section buse est fixée à l'élément couvercle, et une section (22) pliable de liaison est prévue entre le piston et la section buse pour les relier. Un mouvement de haut en bas du piston est positivement absorbé par pliage de la section de liaison.
