<p>Tank cap (2) for the filling pipe of a liquid container, comprising an upper body (6) and a lower body (8) and a liquid stop valve (20), comprising a valve body (22), having a through-passage to the interior and exterior of the cap (2) as well as a pressure equalization valve (18). A valve element in the form of a disc (34) is disposed in the valve body (22) so that a surge of liquid in the filling pipe against the cap (2) will be immediately shut off by the valve disc (34) being displaced by the surge to a position blocking the passage, thus preventing any penetration of liquid through the cap (2). <IMAGE></p> |
