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 une entrée (103) par laquelle arrive le fluide réfrigérant et une sortie (104) par laquelle sort le fluide réfrigérant, caractérisé en ce que un orifice (11) est agencé dans le corps (10) et forme un passage du fluide réfrigérant entre l'entrée (103) et la sortie (104) dudit corps (10), et en ce qu'au moins une partie dudit corps (10) se présente sous la forme d'un actionneur (131, 132, 133, 134) réalisé en matériau électro actif, lequel actionneur (131, 132, 133, 134) est apte à faire varier la section de l'orifice (11), de sorte que le dispositif détendeur (1) passe d'une position d'ouverture dans laquelle le fluide réfrigérant circule de l'entrée (103) à la sortie (104), à une position de fermeture dudit orifice (11).
