A device for making a connection between a volume and the surroundings, comprising an air duct (8) for pressure compensation between the volume and the surroundings. The device is characterised by a container connected to the air duct (8) and having a centrally arranged outlet (3) which opens into the surroundings. As a result, fluid (6) which is transferred from the volume to the container through the air duct (8) is collected in a leakage-free manner by the container, independently of its orientation, as long as the surface level of the fluid (6) is below the level of the outlet (3) while simultaneously allowing said pressure compensation. |
