TYRE PRESSURE SENSOR FOR MOTOR VEHICLES

A tyre pressure sensor for motor vehicles contains a reference pressure chamber (19) in the form of a manometric switch comprising a contact membrane (22) and a contact pin (23). The threshold value of the manometric switch is varied in function of the rotational speed. For this purpose, the referen...

Abstract A tyre pressure sensor for motor vehicles contains a reference pressure chamber (19) in the form of a manometric switch comprising a contact membrane (22) and a contact pin (23). The threshold value of the manometric switch is varied in function of the rotational speed. For this purpose, the reference pressure chamber (19) is sealed on the rim side by an annular membrane (28) whose inner edge is connected to the housing of the manometric switch and whose outer edge (29) is connected via an inertia ring (26) to the contact membrane (22). Détecteur de la pression des pneumatiques d'un véhicule automobile, comportant une chambre de pression de référence (19) réalisée sous la forme d'un interrupteur à pression comprenant une membrane de contact (22) et une tige de contact (23), pour lequel il est prévu, afin d'avoir un déplacement de la valeur-seuil de l'interrupteur à pression, variant en fonction de la vitesse de rotation, que la chambre de pression de référence (19) soit isolée en direction de la jante, par une membrane annulaire (28) reliée, par son bord interne, au boîtier de l'interrupteur à pression et, par son bord externe (29), par l'intermédiaire d'une bague de masse (26), à ladite membrane de contact (22).
