Abstract
L'invention se rapporte à un indicateur de niveau d'un liquide contenu dans un réservoir. L'indicateur comprend une sonde plongée dans le liquide et communiquant avec la chambre remplie de gaz d'une source de pression gazeuse, un dispositif de verrouillage et un système avertisseur, une augmentation de pression dans ladite chambre sollicitant normalement le dispositif de verroulliage dans une position pour laquelle le système avertisseur n'est pas mis en oeuvre. Lorsque le niveau du liquide est insuffisant, la mise en oeuvre de la source de pression a pour seule conséquence l'échappement du gaz par la sonde, de sorte que le dispositif de verrouillage reste dans une position pour laquelle le système avertisseur est mis en oeuvre. Application à la mesure du niveau d'huile dans le carter moteur d'un véhicule automobile.
