Abstract:
An air valve apparatus comprising:a cylindrical body providing an outer cylindrical sidewall having a sealed window for viewing therethrough, the cylindrical body further providing an inner cylindrical sidewall concentric with the outer cylindrical sidewall;the inner cylindrical sidewall providing at one end thereof and integral therewith, an air hose bib adapted by a spring biased valve for receiving air thereinto, and a capping means adapted for removably positioning the inner and outer cylindrical sidewalls in concentric positions;the outer cylindrical sidewall further providing, integral therewith, a valve depressing means enabled for opening a tire stem valve for conducting air thereinto;a movable cylindrical pressure level indicator positioned adjacent to the sealed window between the outer and inner cylindrical sidewalls;the pressure level indicator terminating at one end with a flange extending sealingly between the inner and outer cylindrical sidewalls;a biasing spring positioned between the flange and the capping means, the biasing spring compressible in response to air pressure changes within the apparatus so as to move the pressure level indicating means, thereby providing an indication of said air pressure changes through the sealed window.
