ABSTRACT:
An anti-seepage, self-gauging inflation valve system includes an inlet port and an outlet port; a filler valve for introducing fluid under pressure from the inlet to the outlet port; a vent structure; an isolation chamber communicating with the vent structure; a gauging valve for sealing the chamber from the vent structure and automatically opening when the pressure in the chamber exceeds a predetermined level; an anti-seepage isolation valve for isolating the chamber from the outlet port; and an actuator device for opening the isolation valve to enable access between the gauging valve and the outlet port to vent pressure in excess of the predetermined level while the actuator device holds open the isolation valve.
