ABSTRACT:
An audibly reporting and contemporaneous pressure-relief, automatic tire assembly is disclosed for use in interaction with preexisting valve core stems on a tire of other vessel or with conventional tire rim inflation holes. The assembly of the invention has a channeled valve body having a moving inside pin, and communication from within its channel to a sound board emission port having check-reed position groove at its other end. A pressure-sensitive arc-like mechanism is provided, fabricated to provide an inwardly closing force equivalent to a preselected pressure limit desired for a respective tire or air/fluid-pressured container. This mechanism is mounted in relation to the valve body and supported by a hollow and ported collar so that it seats and exerts closing force against an exposed portion of the check-reed which sits and can move within its position groove. When air or fluid pressure is provided to the valve body, in installed position, the back pressure from this exerts a corresponding force on the check-reed. When this back-pressure force, representing pressure in the tire/container exceeds the force exerted by the pressure-sensitive mechanism leaning on the check-reed, the check-reed moves within its groove allowing excess pressure above the limit to escape, and contemporaneously reporting an audible whistling sound generated by the sound board conditions created by escaping air in adjoining spaces of the check-reed, check-reed groove, and ported support collar in relation to the valve body.
