MEDIUM INSTALLATION OF A VEHICLE, EMPTYING DEVICE FOR A MEDIUM LINE, AND VEHICLE WITH THE MEDIUM INSTALLATION

An emptying device for a medium line of a vehicle, such as a recreational vehicle, can be connected between a medium tank of the vehicle and the medium line to be emptied. A first non-return valve is arranged in a first connecting line between the medium tank and the medium line to be emptied and permits a flow of the medium from the medium tank into the medium line, but blocks a reverse flow. A second connecting line opens into the first connecting line downstream of the first non-return valve. The second connecting line, for emptying the medium line, can be connected to a pressure medium source and can be acted upon by the pressure medium in order to empty the medium line. There is also described a medium installation of a vehicle and a corresponding vehicle.
