<p>An electrical control probe is provided longitudinally movable in a passage of filler valve means and the probe can be retracted and introduced with respect to a container engaged with a counter-pressure filling unit. A proximity switch, loading gas valve, liquid valve and magnetic control valve are affected by probe movement for actuation and deactuation respectively during liquid filling into the container. A sleeve around the probe includes passage means communicating for liquid filling, loading gas supply and exhaust with respect to the container. A control rod engageable with a valve seat collar determines valve opening and closing according to probe position. An electrical plug card and contact strip interconnect electrical and electronic control units for the filling operation.</p> |
