Abstract
Automatic closing sprue valve characterized in that it essentially comprises a cylindrical valve body with an exterior annular projection, closed at the top by an axially orificeed plate and at the bottom by a valve that sits on an elastic ring contained within the interior of the valve. Body, whose valve is provided with an external drive hammer; inside said body there is a compression spring that sits on the internal faces of the valve and upper cover, exerting on it a closing pressure against the elastic ring, and whose opening is performed by overcoming the resistance of the spring when acting on the hammer (Machine-translation by Google Translate, not legally binding)
