Abstract: front page image
(EN)Pressure gauge which is adapted to be continuously mounted on the valve stem of the inflated device. It includes an airtight enclosure positioned within an outer housing which enclosure expands towards the inflated device in response to increasing gas pressure. Cooperating with this expansion of the airtight enclosure is a piston like member (474 and 742), which includes means (472 and 760), for controlling the expansion of the airtight enclosure. The control means is calibrated so that the piston like member moves an axial distance in an amount proportional to the pressure of the gas in the tube. The piston has an indicator band (480) painted thereon which positions itself opposite appropriate psi markings (406) on the outside of the housing. This provides a ready indication of the pressure. The means for releasing the pressure into the expandable, airtight enclosure, is further adapted to enable additional pressurized gas to be introduced into the inflated device. Alternate embodiments provide an airtight enclosure formed by an expandable means (70, 142 or 156), which expand away from the inflated device.
(FR)Une jauge de pression est concue pour etre montee en permanence sur la tige de soupape du dispositif gonfle. Elle comprend une enceinte etanche a l"air positionnee dans un logement externe; cette enceinte se dilate vers le dispositif gonfle en reponse a une augmentation de la pression du gaz. Un organe en forme de piston (474 et 742) cooperant avec cette dilatation de l"enceinte etanche a l"air comprend des moyens (472 et 760) et commande l"expansion de l"enceinte etanche a l"air. Les moyens de commande sont calibres de telle sorte que l"organe en forme de piston se deplace sur une distance axiale proportionnellement a la pression du gaz dans le tube. Le piston possede une bande indicatrice (480) peinte qui se place elle-meme en face d"indications de valeurs en psi (406) sur l"exterieur du logement. Ceci donne une indication directe de la pression. Les moyens de detente de la pression dans l"enceinte expansible etanche a l"air sont en outre adaptes pour permettre l"introduction d"un gaz supplementaire sous pression dans le dispositif gonfle. Des variantes de realisation consistent en une enceinte etanche a l"air formee des moyens expansibles (70, 142 ou 156) qui se dilatent en s"eloignant du dispositif gonfle.
