Abstract:
A delivery device for delivering reducing agent into an exhaust-gas treatment device includes at least one delivery duct with at least one flexible wall region. The flexible wall region can deform when reducing agent in the delivery duct freezes. The flexible wall region separates the delivery duct from a compressed-air chamber which is connected to a compressed-air source. Methods for operating and deactivating a delivery device and a motor vehicle having a delivery device are also provided.
