Title
(EN) PRESSURE AIRLOCK
(FR) SAS DE PRESSION
Abstract
(EN)
A pressure airlock for an inflator or a gauge for use with a valve stem having exterior threads and a valve core, the pressure airlock including a conduit in fluid communication with the inflator or the gauge. A tip extends from the conduit and includes a bore. A core depressor is positioned within the bore and an inner shoulder surrounds the core depressor. An outer shoulder extends from the inner shoulder and extends beyond the core depressor. A is seal positioned on the inner shoulder and the outer shoulder and extends within the tip.

L'invention concerne un sas de pression destiné à un gonfleur ou une jauge à utiliser avec une tige de valve ayant des filetages extérieurs et un noyau de valve, le sas de pression comprenant un conduit en communication fluidique avec le gonfleur ou la jauge. Une pointe s'étend à partir du conduit et comprend un orifice. Un dépresseur de noyau est positionné à l'intérieur de l'orifice et un épaulement interne entoure le dépresseur de noyau. Un épaulement extérieur s'étend à partir de l'épaulement intérieur et s'étend au-delà du dépresseur de noyau. Un joint d'étanchéité est positionné sur l'épaulement interne et l'épaulement externe et s'étend à l'intérieur de la pointe.
