<p>The subject of the innovation is a device by means of which containers in which water accumulates in an undesirable manner are automatically drained. An outer housing (2, 3) which can be inserted into the container bottom is subdivided by a web (8a) into two chambers, of which one is connected to the interior of the container and the other to the environment of the container. The web encloses an aperture (20) which connects the two chambers to each other when a valve member (14) has moved away from a seat (8b) surrounding the aperture. When the valve member rests on the seat, the chambers are separated from each other and the interior space of the container is not connected to the environment of the container. The movement of the valve member is controlled by the water level in the chamber which is connected to the interior space of the container.</p> |
