Abstract

Cet élément thermostatique (1) comporte une coupelle thermoconductrice (10) qui contient une matière thermodilatable (20), un piston (30) déplaçable en translation suivant son axe (X-X) sous l'action de la matière thermodilatable, et une pièce (40) de guidage du piston qui est solidarisée fixement à la coupelle. Afin de renforcer et faciliter l'étanchement de cet élément thermostatique vis-à-vis de l'extérieur, l'invention prévoit que l'élément thermostatique comprend en outre : - un joint d'étanchéité (50), qui est interposé radialement entre le piston et la pièce de guidage, en étant reçu dans une gorge (45) délimitée dans la face d'extrémité axiale (41 A), opposée à la coupelle, de la pièce de guidage, et - une pièce (60) de retenue axiale du joint d'étanchéité dans la gorge, qui est montée autour du piston et qui est fixée à la pièce de guidage et/ou à la coupelle.
