Title
(EN) TRIGGER TYPE LIQUID INJECTOR
(FR) INJECTEUR DE LIQUIDE A GACHETTE
Abstract
(EN)
A synthetic resin-made return spring (6) of a trigger (3), comprising a substrate (12) and a pair of spring pieces (29) for returning a plunger (5), wherein each of the spring pieces (29) further comprises a main leaf spring (32), an auxiliary leaf spring (33), and a lower end (30), the main leaf spring (32) is disposed on the plunger side and has a longitudinal cross section of generally arc shape, the auxiliary leaf spring (33) is disposed on the nozzle head side and has a longitudinal cross section constituting a generally constant load leaf spring, the main leaf spring (32) and the auxiliary leaf spring (33) are connected to each other at the upper end and a lower end (30), respectively, and the locus of elastic deformation of the main leaf spring (32) is substantially identical to an arc locus (Y, Z) including a tangential line (X) within the upper surface of the substrate (12).
(FR)
L'invention concerne un ressort de rappel (6) de gâchette (3), en résine synthétique, constitué d'un substrat (12) et d'une paire de pièces à ressort (29) pour rappeler un poussoir (5). Chaque pièce à ressort (29) comporte un ressort à lame principal (32), un ressort à lame auxiliaire (33) et une extrémité inférieure (30), le ressort à lame principal (32) étant prévu sur le côté du poussoir et comportant une section longitudinale généralement de forme arquée. Le ressort à lame auxiliaire (33) est prévu sur le côté de la tête de buse et possède une section longitudinale formant un ressort à lame à charge généralement constante. Le ressort à lame principal (32) et le ressort à lame auxiliaire (33) sont reliés l'un à l'autre, respectivement au niveau de l'extrémité supérieure et d'une extrémité inférieure (30), et le site de déformation élastique du ressort à lame principal (32) est sensiblement identique à un site en arc (Y, Z) comprenant une tangente, au sein de la surface supérieure du substrat (12).
