<p>The filling channel in the top piece of a liquid gas cylinder or a similar container to be filled only to a certain level determined by a float includes a closing valve which in the prescribed filling position of the container is raised from its seat by a pin on a universally journalled pivotal member which by a load is urged toward a given orientation in space. A tilting of the container causes the pivotal member to be rotated, thereby entailing a lateral displacement of the pin away from the closing valve which then occupies its closing position against the seat and prevents further filling until the container reoccupies the prescribed position. When the maximum filling level has been reached, the float causes closing of the same valve, for instance by dominating the load so as to provoke a rotation of the pivotal member.</p> |
