The invention relates to a filler neck () for an auxiliary liquid reservoir for a motor vehicle, in particular for a urea reservoir, having a neck housing (), which defines a mouth hole stub () for a filler nozzle () and a filling channel () leading into the reservoir, wherein a receiving structure for a filler nozzle () is provided within the neck housing (). At least one venting path, which is of enlarged cross section, at least in a section or sections, and of chamber-like or labyrinth-like design, is formed within the neck housing (), allowing a venting flow parallel and counter to the refilling volume to flow through the neck housing () during refilling.

Filler neck for an auxiliary liquid reservoir

The invention relates to a reducing agent tank for holding a liquid reducing agent as a so-called SCR tank. The SCR tank comprises at least one device for deaerating the tank, which device is closed off by means of at least one pressure-compensating element which permits an exchange of gas but which closes off the tank in a liquid-tight manner. The reducing agent tank also comprises at least one deaeration line which communicates with the pressure-compensating element, with the deaeration line being guided at least to a point above the maximum permissible fording level of the tank when the tank is in the installation position. The deaeration line has at least one first downward-sloping line section which branches into a second rising line section for deaeration and a third falling line section for gravity-induced condensate drainage.

Operating fluid tank

A discharge nozzle for the filling pipe of a motor vehicle fuel tank for the introduction of fuel into the tank includes a check flap which is held by spring loading in a closed position, being caused to bear pivotably against the mouth opening of the nozzle. The check flap is sealed in relation to the mouth opening of the nozzle by way of at least one sealing element with a peripherally extending sealing lip. The sealing lip extends radially outwardly in relation to the cross-section of the discharge mouth opening.
