Abstract:
An air pressure gauge is provided integrally with a valve stem extender as used with automotive vehicle wheels mounting tubeless or tube-type air inflated tires. The gauge comprises a Bourdon tube concentrically coiled about the barrel of the valve stem extender and communicated to the interior of the barrel through an orifice provided in the wall of the barrel. The Bourdon tube carries a dial pointer at its outer end which registers with a stationary dial face bearing visible indicia indicating tire inflation pressure. An annular viewing crystal is provided over the pointer and dial face. The gauge displays air inflation pressure reading constantly and need not be disturbed while air is being added to a tire.
