Abstract

Cette invention se rapporte à un dispositif d'injection liquide chimique, ledit dispositif étant équipé d'un boîtier (113) comportant une dépression (114) qui permet de maintenir un cylindre (210), ainsi qu'un mécanisme d'entraînement du piston (130) doté d'une section de compression du piston qui permet de pousser sur un bouton pressoir du piston (220). Le mécanisme d'entraînement du piston (130) est contrôlé de telle sorte que, lorsque la section de compression du piston se trouve dans les derniers segments de sa course et qu'elle atteint la fin de sa progression, sa vitesse de déplacement est inférieure à celle observée auparavant dans d'autres segments. Lesdits derniers segments signifient à la fois le dernier segment d'une course de la section de compression du piston depuis sa position initiale jusqu'à ce qu'elle touche le bouton pressoir du piston, et aussi le dernier segment d'une course de la section de compression du piston depuis sa position avancée jusqu'à son retour à la position initiale.
