CA 2300109

The invention concerns a spray pump (3) capable of being actuated by a hand lever, to be mounted on dispensers (2) or the like. Said pump comprises a piston pump (6) capable of sliding linearly in a pump chamber (7) on the housing side. Said piston is connected, on the rear side of an outlet (9), to the hand lever (5) and returns to its base position urged by a spring. The invention aims at producing a pump which is both simple and reliable by associating two articulating parts (I, II) with the lever (5). One (I) of said parts is located so as to slide in a linear slider on the housing side, and the other (II) is fixed to the housing, on the side opposite the outlet (9), such that the two articulating parts (I, II) are connected by mutually collapsible contiguous parts (a, b).

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.
