Abstract
The invention relates to an arrangement (100) having a liquid tank (10), at least one line (11, 11a, 11b) connected to the liquid tank (10), through which liquid (F) can be transported from the liquid tank (10), and a pump (13) connected to the at least one line (11, 11a, 11b) for conveying the liquid (F) from the liquid tank (10) through the at least one line (11, 11a, 11b) in the direction of flow (R) during an operating phase, wherein a pressure accumulator (14) connected to the at least one line (11, 11a, 11b) is provided, by means of which a pressure can be generated in the at least one line (11, 11a, 11b) outside of the operating phase, and a ventilating element (15, 15a, 15b), which can be transitioned into an open position and into a closed position, is arranged along the at least one line (11, 11a, 11b), wherein, outside of the operating phase, a pressure impulse within the at least one line (11, 11a, 11b) can be generated by the pressure generated by the pressure accumulator (14) and a subsequent transition of the ventilating element (15, 15a, 15b) into the open position in order to drain the line (11, 11a, 11b) of the fluid (F).
