Abstract

Gicleur de fluide (10) de refroidissement de piston d'un moteur à combustion interne comprenant : - une chambre cylindrique (11), - une ouverture de sortie (14) dudit fluide depuis la chambre cylindrique, caractérisé en ce que ledit gicleur comprend un clapet d'obturation (25) de l'ouverture apte à avoir un premier type de déplacement en fonction de la pression et un second type de déplacement en fonction de la température différent du premier type, pour autoriser le passage de fluide par l'ouverture de sortie à partir d'un seuil de pression et à partir d'un seuil de température.
