ABSTRACT:
A valve device serving to prevent overfilling of portable containers, particularly liquid gas cylinders, includes a ball which is freely rotatable relative to a spherical seating face in a casing having a filling channel extending to said seating face. The ball has a through passage which in the prescribed filling position communicates with the channel, and the ball is connected to a load member tending to keep the ball, and thus its passage, in a given orientation so that the communication is broken when the container is tilted away from the prescribed filling position.
The device further includes a valve member controlled by a float and operative to interrupt the filling operation after a predetermined filling level has been reached in the container.
