Patent
CA 2490651
An inflatable bladder (10) is provided with an inflation valve device (2) that includes a sleeve member (21), a tubular indicator (22) mounted movably in the sleeve member and marked with indicia, an inflation needle (24) mounted in the indicator, and an urging member (29) disposed between the sleeve member and the indicator in such a manner that outward movement of the indicator resulting from the pressure difference between the pressure in the bladder and the atmospheric pressure results in displacements of the urging member.
Une chambre (10) gonflable est pourvue d'un dispositif (2) de valve de gonflage qui comprend un manchon (21), un indicateur (22) tubulaire monté mobile dans ce manchon et marqué avec des inscriptions, une aiguille (24) de gonflage montée dans l'indicateur et un élément de poussée (29) placé entre le manchon et l'indicateur de sorte que le déplacement vers l'extérieur de l'indicateur résultant de la différence de pression entre la chambre et l'atmosphère entraîne un déplacement de cet élément de poussée.
