Abstract
The main valve slides in the direction for its opening when the plunger is pushed in. This causes the nozzle hole and the main valve's operating bore to be communicated, which then causes the compressed gas in a pressure vessel to open the follower valve's check valve thus discharging the gas to the outside of the pressure vessel through the follower valve's communicating bore. When the pressure at the discharge side exceeds the pressure of the pressure vessel during such discharge, a back-flow pressure causes the follower valve to slide, thus closing the follower valve's operating bore and the communicating bore with the check valve. This closes the gas's passage and prevents its back-flow into the pressure vessel. When charging a high-pressure gas, any moisture which has penetrated into the nozzle hole and/or the main valve's operating bore can be blown off by discharging residual pressure in the pressure vessel.
