Abstract: A conveying unit for conveying reducing agent from a tank to an exhaust gas treatment device for treating the exhaust gases from an internal combustion engine, includes a pump having a drive or drive unit and a pump chamber unit or containment. The pump chamber unit or containment at least partly delimits a pump chamber and the drive or drive unit and the pump chamber unit or containment are detachable from one another.

Abstract: An assembly having a system for preventing mechanical vibration includes a honeycomb body disposed in the interior of a tubular casing for permitting a fluid flow therethrough. The tubular casing has at least one reinforcing structure which locally increases vibration resistance and is connected to the honeycomb body only in at least one partial region of its inner surface at least in a surrounding region of the reinforcing structure only over a part of the inner periphery. The reinforcing structure projects from the outer surface of the tubular casing by more than the thickness of the tubular casing. The system according to the invention enhances both the durability of a honeycomb body as well as its connection to a tubular casing.
