Claim:
A tire valve-gauge combination comprising: i. a rim-attaching base portion having: a. a tire rim sealing portion having a lower body portion larger than the valve perforation of a conventional tire rim and a central neck portion having an outside diameter equal or lesser than said rim perforation to form a seal with said tire rim, b. a rigid tubular inner sleeve moldedly integrated within the mid and upper inner cylindrical portion of the base, c. a plurality of inwardly and upwardly protruding ridges adapted to prevent full descent of a piton, and d. a piston is fixedly attached to a stem where, said piston is flexibly resilient and is adapted with a concave shape at its very bottom surface thereby promoting a durable continuous seal to the inner wall surface of the inner sleeve unless said piston is placed at or near the bottom area of said inner sleeve, ii. a gauge portion having: a. a tubular transparent rigid material onto which markings are disposed so as to allow user to view the pressure at the valve, b. a lower base attaching portion fixedly attached to said base, c. an upper cap base attaching portion also fixedly attached to the lower portion of said cap base, d. an indicator frictionally attached to the upper end of the piston stem of the base portion, e. a lower spring frictionally engaged to the upper portion of the indicator, and f. a divider disk located between the joint where the cap base portion and gauge portion meet, iii. A cap base made from a rigid material having: a. a generally tubular form and an array of circular and semi-circular inwardly protruding rings integral with the inner surface of said tubular cap base wherein; i. the upper ring is fully circular, ii. the upper stop ring is a pair of quarter rings, iii. the lower stop ring is also a pair of quarter rings, and iv. the lower ring is also fully circular, iv. A cap portion having: a. a generally tubular form, b. a lower lip extending slightly outwardly from the bottom periphery thereof, c. a body portion having a mid to lower portion with an outer diameter generally equal to that of the opening at the top of the cap base, d. an upper portion having a diameter slightly reduced than that of the cap's mid to lower portion, e. an opening at the very top of said cap is provided and comprises a narrow top portion extending only slightly then beveled outwardly in two stages, f. a plunger extends through the cap base and into the upper portion of the gauge, g. a dust cap, frictionally attached to said plunger is adapted to auto center to the opening at the top of the cap, where the upper portion of the dust cap has an upper sealing portion of equal or slightly smaller diameter than that of the cap opening with which it mates, and h. an upper spring slidably engaged around the outside of the plunger wherein said upper spring is restedly engaged with the under side of the dust cap and also restedly engaged to the divider disk thereby compressing said spring when the cap is depressed downwardly to the end of its travel distance.
