The present invention discloses an improved operating fluid reservoir having a venting and/or air admission valve. The operating fluid reservoir is characterized in that a valve housing is formed integrally with an operating fluid reservoir wall. A vent opening, via which a valve housing interior is in fluid communication with a vent line, is embodied as a through opening through the operating fluid reservoir wall. A valve body, which is arranged in the valve housing interior, can be introduced into the valve housing interior via an introduction opening in the valve housing. The valve body comprises a holding device, by which the valve body is held movably in the valve housing.

Operating fluid reservoir having an integrated venting and/or air admission valve

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 filler neck for an operating-liquid tank () for a motor vehicle. The filler neck () comprises a mouth-hole neck (), into which a nozzle can be inserted in order to fill the operating-liquid tank (). A ventilation path is provided in the filler neck (), which ventilation path allows a ventilation flow parallel and oppositely to the filling volumetric flow through the mouth-hole neck () during filling. The filler neck () according to the invention is characterized in that the ventilation path comprises at least one ventilation channel () provided in a wall arrangement () of the mouth-hole neck (), which at least one ventilation channel is at least partially surrounded by an outer wall () and an inner wall () of the wall arrangement () along the longitudinal extent of the at least one ventilation channel.

The present invention discloses a filling device () for a motor vehicle operating fluid container (). The filling device () comprises a mouth hole connection piece (), into which a dispensing valve () can be introduced in order to fill the operating fluid container (). The filling device () further comprises a compensation chamber () to which the mouth hole connection piece () is connected in fluid terms. A connection piece () of the filling device () is arranged between the operating fluid container () and the compensation chamber () and is connected in fluid terms to the operating fluid container () and the compensation chamber (). The filling device () is distinguished in that the connection piece () protrudes into the compensation chamber (), the connection piece () is arranged so as to face the mouth hole connection piece () and to be spaced apart therefrom, the connection piece () is surrounded by the compensation chamber (), and a dispensing valve () can be introduced through the mouth hole connection piece () into the connection piece ().
