Abstract:
A delivery device for delivering liquid reducing agent includes a reducing agent tank. At least a delivery unit, at least one first compensation element, a reducing agent line and a metering unit together have an overall volume to be filled with a reducing agent and are configured for delivering, conducting and metering the reducing agent from the reducing agent tank. The at least one first compensation element is configured for reducing the overall volume when a negative pressure occurs in the delivery device. A method for compensating freezing of a reducing agent in a delivery device and a motor vehicle having a delivery device, are also provided.
