Abstract: A body through which a medium can flow, in particular a body through which a fluid and/or gas can flow, with at least one exterior, wherein the body through which a medium can flow is self-supporting or includes at least one supporting body that provides mechanical stability, as well as a greenery system with at least one greenery element for installation on a surface, including at least one such body through which a medium can flow, in particular a body through which a fluid and/or gas can flow.

Abstract: The invention relates to a filler neck (1) for an auxiliary liquid reservoir for a motor vehicle, in particular for a urea reservoir, having a neck housing (9), which defines a mouth hole stub (10) for a filler nozzle (7) and a filling channel (11) leading into the reservoir, wherein a receiving structure for a filler nozzle (7) is provided within the neck housing (9). 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 (9), allowing a venting flow parallel and counter to the refilling volume to flow through the neck housing (9) during refilling.

Abstract: 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.

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 pressure-tight manner. The reducing agent tank (1) also comprises at least one deaeration line (5) which communicates with the pressure-compensating element, with the deaeration line (5) 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 (5) has at least one first downward-sloping line section (5a) which branches into a second rising line section (5b) for deaeration and a third falling line section (5c) for gravity-induced condensate drainage (FIG. 1).

Abstract: The invention relates to a reducing agent tank (1) for motor vehicles, having at least one filler pipe (3) which is provided with a filler opening (4), having at least one device for filling deaeration and having means for limiting the fill level during filling, with the device for filling deaeration comprising at least one filling deaeration line (7) which extends at least in sections above the maximum fill level in the filler pipe (3) and/or in the tank (FIG. 2).

Abstract: 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.
