Problems solved by technology
But this is energy-intensive and costly
In addition, additional space is required for the heating element, which has to be arranged on larger lengths of pipeline
In addition, the design of the entire heating device with several heating elements is expensive in order to achieve a constant heating power over the entire length of the pipeline

Embodiment Construction
[0027] figure 1 and figure 2 A device 100 is shown in each case with a storage tank 10 from which the liquid F is conveyed or guided in the flow direction R via the line 11 to the consumer 12 . The consumer 12 may for example be part of a motor vehicle, eg an internal combustion engine, into which the liquid F in the form of water from the reservoir 10 may be introduced, in particular injected, in order to reduce emissions and / or improve performance.
[0028] During the operating phase, the liquid F is delivered to the consumer 12 via the line 11 in the flow direction R by means of the pump 13 connected to the line 11 .
[0029] After the completion of the operating phase, ie when no more liquid F is delivered to the consumer 12, residual liquid should be prevented in the line 11 in order to prevent the liquid F from freezing at low temperatures.
[0030] In order to remove the residual liquid F from the line 11, a pressure accumulator 14 is provided, by means of which a pr...

The invention relates to a device (100) having: a liquid storage tank (10); at least one line (11, 11a, 11b) connected to said liquid storage tank (10), through which line can be obtained from said liquid storage tank (10) A liquid tank (10) conveys liquid (F); and a pump (13) connected to said at least one line (11, 11a, 11b) for passing from said liquid storage tank (10) through said liquid storage tank (10) during an operating phase At least one line (11, 11a, 11b) conveys the liquid (F) in the flow direction (R), wherein a pressure accumulator (14) connected to the at least one line (11, 11a, 11b) is provided, through which the accumulator (14) is provided. A pressure press can generate pressure in said at least one line (11, 11a, 11b) during non-operational phases, and along said at least one line (11, 11a, 11b) a ventilation element can be arranged that can be switched between an open position and a closed position (15, 15a, 15b), wherein in the non-operational phase, the pressure generated by the accumulator (14) and the subsequent switching of the ventilation element (15, 15a, 15b) to the open position, can be A pressure pulse is generated in at least one of the lines (11, 11a, 11b) to evacuate the liquid (F) from the lines (11, 11a, 11b).
Description
technical field [0001] The invention relates to a device having: a liquid storage tank; at least one line connected to the liquid storage tank, through which liquid can be conveyed from the liquid storage tank; and a pump connected to the at least one line , the pump is used to transport the liquid from the liquid storage tank in the flow direction through at least one line during the operation phase. The invention also relates to a method for emptying at least one line connected to a liquid storage tank, through which line liquid is conveyed from the liquid storage tank in the flow direction by means of a pump in the operating phase. Background technique [0002] Such a device can be provided, for example, in a motor vehicle. In the storage tank, for example, water can be stored as a liquid, which can be fed into the combustion chamber of the internal combustion engine through a line connected to the liquid storage tank, for example to achieve reduced emissions and / or impr...
