Abstract

The filling valve (F) has a valve element (V) with a shaft (4), adjustable relative to a valve seat (P). The shaft is in a setting device (E). It can be moved by the unlocking drive against a return force from a closed position to a preset open position, bringing a counter-stop (R) on the shaft against a fixed stop (S). An impact damping device (G) is fitted in the setting device between the counter-stop and the stop.
