Tank device for storing a liquid medium that reduces pollutant levels
View Patent ↗A tank device for storing a liquid medium for reducing pollutant levels in exhaust gases includes a container for storing the liquid medium, having a container wall, which is a first plastic at least in a first contact area. The tank device furthermore includes a support element, which is arranged in an aperture in the container wall and has an overmolding which is a second plastic at least in a second contact area. The second contact area is coupled to the first contact area of the container wall in a substantially liquid-tight manner.
1. A tank device for storing a liquid medium that reduces pollutant levels in exhaust gases, comprising:
a container configured to store the liquid medium, the container having a container wall that comprises a first plastic at least in a first contact area; and
a support element arranged in an aperture in the container wall and having a coating comprising a second plastic at least in a second contact area, wherein the second plastic of the second contact area is coupled to the first plastic of the first contact area of the container wall in a liquid-tight manner.
2. The tank device as claimed in claim 1 , wherein the first plastic and the second plastic comprise polyethylene.
3. The tank device as claimed in claim 1 , wherein the support element comprises a sensor device.
4. The tank device as claimed in claim 3 , wherein the sensor device comprises a temperature sensor element.
5. The tank device as claimed in claim 4 , wherein the temperature sensor element has an electrical resistor with a negative temperature coefficient.
6. The tank device as claimed in claim 4 , wherein the temperature sensor element is arranged at an end of the support element that points into the container.
7. The tank device as claimed in claim 1 , wherein the aperture is arranged in spatial proximity to a discharge opening of the tank device.
8. The tank device as claimed in claim 1 , wherein the support element comprises a locking device for at least one of mechanical coupling and electrical coupling of at least one further subassembly.
9. The tank device as claimed in claim 8 , wherein the support element has electrical connections at a second end pointing outward out of the container, that are coupled electrically to at least one of a sensor device and the locking device.
10. The tank device as claimed in claim 8 , wherein the at least one further subassembly comprises an ultrasonic sensor.
