Abstract
A device for providing liquid reducing agent for an exhaust-gas treatment device includes a tank and a delivery unit with an intake or suction point in the tank at which reducing agent can be suctioned or drawn out of the tank. The intake point is covered by a separation layer in such a way that a closed intermediate space is formed between the intake point and the separation layer. The separation layer has a higher flow resistance to reducing agent in an outflow direction from the intermediate space into the tank than in an inflow direction from the tank into the intermediate space. A motor vehicle having the device is also provided.

A device for providing liquid reducing agent for an exhaust-gas treatment device, the device comprising:
- a tank;
- a delivery unit having an intake point disposed in said tank and configured to draw-in reducing agent from said tank;
- and
- a partition layer covering said intake point, forming a closed intermediate space between said intake point and said partition layer and defining an outflow direction from said intermediate space into said tank and an inflow direction from said tank into said intermediate space;
- said partition layer having a higher flow resistance for reducing agent in said outflow direction than in said inflow direction.
