Abstract

Indicateur visuel du gonflage insuffisant d'un pneumatique. Incorporé à la valve d'un pneumatique, cet indicateur, qui est simple, peu coûteux, sûr et durable, permet au conducteur d'un véhicule de se rendre compte d'un simple coup d'oeil du gonflage insuffisant des pneumatiques de ce dernier. Il présente notamment l'avantage, par rapport aux dispositifs analogues de la technique anterieure, de mieux empêcher l'air sous pression de s'échapper du pneumatique, quelle que soit la pression interne de ce dernier. Application à l'industrie automobile.
