The invention relates to a drainage device (16) for draining an interior (14) of a vehicle body, wherein the drainage device (16) can be integrated in an underframe (10) of the vehicle body and, at a first end thereof, which is provided for forming a floor region (12) of the interior (14), forms an inlet region (18) for the water, at an opposite, second end, which is provided for forming a region of the lower side of the vehicle body, forms an outlet region (22) for the water, and has a fluid path (24) connecting the inlet region (18) to the outlet region (22) in terms of flow. It is provided that the drainage device (16) furthermore has a valve (26) with at least one closure body (30, 32) for closing the fluid path (24) in a gastight manner depending on a pressure difference between the pressure at the first end (pi) and the pressure at the second end (pu) of the drainage device (16), a reservoir (28), which forms the inlet region (18), for collecting water from the interior (14), forming a water column, and an actuating device (42) for opening the valve (26) depending on the height of the water column. The invention furthermore relates to a corresponding underframe (10) for a vehicle body and to a corresponding vehicle body of a vehicle. |
