    摘要: The present invention discloses a method and operating liquid container system for controlling the internal pressure of an operating liquid container of a motor vehicle, wherein the method includes determining an internal pressure of the operating liquid container by means of a pressure sensor arranged in an operating liquid container interior; comparing the determined internal pressure with a predetermined maximum internal pressure by means of an electronic control device; outputting an opening signal from the control device to a vent valve that is arranged in a vent line or between the operating liquid container interior and the vent line, wherein the vent line fluidically connects the operating liquid container interior to the atmosphere when the determined internal pressure is equal to the maximum internal pressure or above the maximum internal pressure; and transferring the vent valve into an open position.

    摘要: 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).
