Abstract
In a spreader for winter service vehicles, brine is filled from a tank sack into additional tanks by purely hydrostatic effect substantially without the use of pumps, by the tank sack being so filled for example by excess pressure that the brine is urged through a liquid line where it forms a closed liquid column. The exit end of the liquid line lies below the entrance end of the liquid line so that, upon filling, the liquid from the tank sack automatically flows into the additional tanks due to hydrostatic forces. Upon emptying the liquid tank, the liquid also flows in a corresponding manner from the tank sack into the additional tanks, thereby completely emptying the tank sack.

16. A method for filling a liquid tank of a spreader for winter service vehicles, wherein the liquid tank has a first tank container and at least one second tank container connected to the first tank container via a liquid line, and wherein the first tank container is a spreading material container which is coupled or is coupleable to a spreading device for spreading solid spreading materials received in the spreading material container, or a tank sack or rigid insertable tank received in the spreading material container, comprising the steps:
-
filling the first tank container with liquid up to a moment as of when the liquid filled in the first tank container begins to flow through the liquid line into the at least one second tank container, and filling the at least one second tank container with liquid from the first tank container through the liquid line following the above-mentioned moment, or filling the at least one second tank container with liquid up to a moment as of when the liquid filled in the at least one second tank container begins to flow through the liquid line into the first tank container, and filling the first tank container with liquid from the at least one second tank container through the liquid line following the last- mentioned moment. - View Dependent Claims (17, 18, 19, 20)

21. A method for emptying a liquid tank of a spreader for winter service vehicles, wherein the liquid tank has a first tank container and at least one second tank container connected to the first tank container via a liquid line, a first line opening of the liquid line lies in the first tank container, and the first tank container is a spreading material container which is coupled or is coupleable to a spreading device for spreading solid spreading materials received in the spreading material container, or a tank sack or rigid insertable tank received in the spreading material container, comprising the step:
-
removing liquid from the first tank container through the second tank container by a second line opening of the liquid line that is so disposed that upon removal of the liquid from the second tank container liquid from the first tank container flows into the second tank container solely due to hydrostatic forces, or removing liquid from the second tank container through the first tank container by a second line opening of the liquid line that is so disposed that upon removal of the liquid from the first tank container liquid from the second tank container flows into the first tank container solely due to hydrostatic forces. - View Dependent Claims (22, 23)

- 24. A spreader for winter service vehicles having a liquid tank, comprising at least one first tank container and at least one second tank container connected to the first tank container via a liquid line, wherein the first tank container is a spreading material container which is coupled or is coupleable to a spreading device for spreading solid spreading materials received in the spreading material container, or a tank sack or rigid insertable tank received in the spreading material container, and wherein the liquid line is attached at a first end to the first tank container or protrudes thereinto and possesses there a first line opening, and is attached at a second end to the at least second tank container or protrudes thereinto and possesses there a second line opening, wherein the liquid line is arranged to transport liquid from the first tank container through the liquid line into the second tank container, or vice versa, without any device for actively conveying the liquid and solely due to hydrostatic forces.
