- the outlet openings of the purge line 116 are arranged at a distance from the container opening 72.
- the system 10 according to the invention has increased operational safety.
- the reservoir 46 can be filled with the storage fluid when the valve 104 is correspondingly switched. There is a flow connection through the inlet
- the outlet opening 114 is spaced relative to the edge 62, and the reservoir 46 is filled via a free, extending through the air path and through the container opening 60 therethrough.
- the container opening 60 released in the open position of the wall section 80 makes it possible to vent the storage container 46 during filling for limiting the pressure.
- the pressure in the reservoir 46 is limited by, and this is protected, for example, against bursting.
- a backflow of the liquid into the supply line 20 is avoided.
- the liquid level may increase until the storage liquid at the edge 62 exits from the container interior 58.
- the outlet opening 114 is spaced from the maximum liquid level. This avoids a potential risk of contamination of the liquid line 88 and the supply line 20 by particles and / or germs in the liquid in the reservoir 46.
- the container opening 60 is an overflow opening.
- the liquid can overflow over the edge portion 66 situated deeper in relation to the edge portion 64, wherein overflowing storage liquid is collected in the container interior 70 of the dirty liquid container 50. This avoids that overflowing storage liquid enters the interior of the housing 32 and this dirty or damaged.
