A tank arrangement for storing a urea solution or water, comprising:
- a tank container which encloses a tank space, wherein the tank container has a bottom side and a top side which is disposed opposite from the bottom side, wherein the urea solution or the water is stored in the tank space of the tank container, and wherein the urea solution or the water fills the tank space up to a liquid surface of the urea solution or the water;
- a swirl pot, wherein the swirl pot is disposed in the urea solution or the water in the tank space and below the liquid surface and has a swirl pot opening;
- and
- a suction jet pump which has a nozzle, a propulsion jet line, and a suction jet line, wherein the propulsion jet line and the suction jet line open into the nozzle and wherein the nozzle has an outlet opening;
- wherein the nozzle is disposed above the liquid surface and above the top side of the tank container at a distance above the swirl pot opening with the outlet opening directed toward the swirl pot opening such that freezing of the nozzle is prevented.
