Abstract

L'invention concerne une pompe de pulvérisation (3) pouvant être actionnée par un levier à main, destinée notamment à être installée sur des flacons (2) ou similaires. Cette pompe comprend un piston de pompe (6) pouvant coulisser linéairement dans une chambre de pompe (7) côté boîtier. Ce piston est raccordé, sur le côté arrière d'un orifice de sortie (9), au levier à main (5) et reprend sa position de base sous l'effet de la sollicitation d'un ressort. L'invention vise à créer une pompe à la fois simple et fiable. A cet effet, deux parties d'articulation (I, II) sont associées au levier (5). L'une (I) de ces parties est placée de façon à coulisser dans une glissière linéaire côté boîtier, et l'autre (II) est fixée au boîtier, sur le côté opposé à l'orifice de sortie (9), de sorte que les deux parties d'articulation (I, II) sont raccordées par des parties jointives (a, b) pouvant être infléchies l'une par rapport à l'autre.
