PROCESS AND APPARATUS FOR FILLING N2 GAS INTO TIRE |
摘要 |
A process for filling N2 gas into a tire assembled onto a rim to hold a recommended internal pressure comprises discharging air inside the tire prior to the filling of N2 gas to render the inside of the tire into a state lower than atmospheric pressure and filling N2 gas into such a tire. An apparatus for carrying out the above process comprises a single inlet path, at least t wo outlet paths and a membrane module for separating air introduced through the inlet path into O2 gas and N2 gas and feeding these gases into respective outlet paths, wherein an outlet path for feeding N2 gas in the outlet paths is connected at its top to a valve for inflating a tire assembled onto a rim under an internal pressure and a discharge path for discharging air inside the tir e prior to the filling of N2 gas is provided on the way of such an outlet path .
