    摘要： A delivery device for delivering a liquid additive out of a tank to an exhaust-gas treatment device includes a delivery duct with an overall volume and a pump disposed in the delivery duct. The delivery duct has a flexible wall portion, downstream of the pump in a delivery direction, with an outer side of the flexible wall portion situated opposite the delivery duct and bearing against a stop when a pressure in the delivery duct lies in a predefined operating pressure range. A spring element which is disposed on the outer side is constructed to deform the flexible wall portion in such a way that the overall volume is reduced in size when the pressure in the delivery duct is lower than a threshold pressure. A method for compensating a formation of ice in a delivery device and a motor vehicle having a delivery device are also provided.

    摘要： A method for operating a feed pump operating in a pulsating manner in a feed unit to feed a liquid operating substance in a feeding direction, is used in a motor vehicle. The feed pump has a feed piston and a drive coil for driving the feed piston. The feed unit has a pressure sensor downstream of the feed pump in the feeding direction. A voltage profile is firstly applied to the drive coil. A feed stroke of the feed piston is subsequently carried out in accordance with the voltage profile. In this context, a pressure profile in the feed unit downstream of the feed pump in the feeding direction is monitored. This pressure profile is subsequently evaluated. The voltage profile is subsequently adapted as a function of at least one characteristic property of the pressure profile. A motor vehicle having a feed pump is also provided.

    摘要： A delivery unit for extracting liquid additive from a tank can be mounted on the tank and includes a fill level sensor for measuring the fill level of liquid additive in the tank. The fill level sensor is set up to emit waves into an emission region of the tank, and the fill level can be measured by using a propagation time measurement of the waves reflected by a liquid surface and striking the fill level sensor again. At least one first reference surface extends at least partially into the emission region and is at a first distance from the fill level sensor. The at least one first reference surface is disposed on a separate calibration component mounted on an outer side of a housing of the delivery unit. A tank for storing liquid additive, a motor vehicle and a method for monitoring a fill level are also provided.

    摘要： 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.
