Abstract

Les poches d'air piégées dans le système de refroidissement peuvent endommager l'ensemble du système moteur. La présente invention concerne un ensemble thermostat verrouillable libre (1) doté d'une structure de purgeur d'air automatique. Plus particulièrement, la présente invention concerne un ensemble thermostat (1) dont le cadre inférieur (10) et le cadre supérieur (20) verrouillables ne sont pas en prise, ce qui permet de verrouiller une bille (30) à l'intérieur du logement de la bille (31) afin de fournir un mécanisme de purgeur d'air automatique. L'un des objectifs du purgeur d'air de l'ensemble thermostat (1) est de permettre à l'air piégé dans le système de refroidissement du moteur de traverser l'ensemble thermostat (1) doté d'une structure de purgeur d'air automatique et ainsi d'être éliminé.
