Abstract Filling and emptying valve for containers and especially for inflatable cushions for cargo protection. The valve comprises a valve housing for mounting in an opening in a wall of a container or cushion and a valve holding body with emptying, filling and closing valves. The emptying and closing valves define a valve chamber, in which the non-return type filling valve opens. In the valve housing the valve holding body is movable between three working positions, a first position in which the valve is completely closed, a second position in which the closing valve is open and connects the valve chamber with the interior of the container or cushion and permits filling the container or cushion through the filling valve, and a third position in which the emptying and closing valves are open for connecting the interior of the container or cushion with the atmosphere.
Filling and emptying valve, comprising a valve housing for mounting in an opening in a wall of a container; a valve holding body; emptying, filling and closing valves in said valve holding body; said valve holding body being mounted in and coaxially with said valve housing; means defining a valve chamber, said valve chamber defining means consisting of said emptying and closing valves, said valve housing and said valve holding body; said filling valve opening into the valve chamber; said valve holding body being axially movable in relation to said valve housing and positionable in three working positions therein, a first working position, in which said emptying and closing valves are closed, a second working position in which said closing valve is open and connects the valve chamber with the interior of the container and permits filling the container through said filling valve, and a third position in which said emptying and closing valves are open for connecting the interior of the container with the atmosphere, said emptying and closing valves having valve seats which consist of bore-defining means of said valve housing and having valve members which consist of sealing rings mounted on said valve holding body.
