Abstract

L'invention concerne un dispositif détendeur (1) destiné à être installé dans un circuit de climatisation comprenant un corps (10) propre à être traversé par un fluide réfrigérant, ledit corps (10) comprenant un compartiment d'entrée (101) dans lequel arrive le fluide réfrigérant et un compartiment de sortie (102) par lequel sort le fluide réfrigérant, ledit dispositif détendeur (1) comportant en outre un ensemble de moyens de détente propres à faire passer ledit fluide réfrigérant du compartiment d'entrée (101) au compartiment de sortie (102), caractérisé en ce que les moyens de détente comprennent un orifice (11) et une tige (12) propre à faire varier la section de passage dudit orifice (11), ladite tige (12) étant rattachée, sur une de ses extrémités, à un moyen de déplacement (13) de ladite tige (12), et en ce qu'au moins une partie du moyen de déplacement (13) comporte un actionneur composé de matériaux électro actifs, lequel actionneur a une épaisseur variable en fonction de la tension qu'on lui applique, de manière à permettre de déplacer la tige (12).
