<p>An automatic liquid-supply stopper plug has a casing body which has an inlet port and a discharge port. Within the casing body, an inverted cup shaped member and a valve seat member are provided to be opposed to each other. A movable valve member is positioned so that it can slide on the inverted cup shaped member and the valve seat member to open or close a passage of liquid through the valve seat member. A first conduit which communicates with the discharge port is provided for pushing the movable member upwardly. A second conduit which communicates with the discharge port is provided for pushing the movable valve member downwardly when a preset level of liquid is obtained to stop the liquid-supply.</p> |
