Embodiment Construction

[0048] In the following description, the same reference numerals represent the same components or the same features, so that the descriptions about the components given with reference to the drawings are also applicable to other drawings, and repeated descriptions are avoided.

[0049] as from figure 1 It can be seen that the filler neck 1 according to the invention is arranged on the filling tube 2 of the operating fluid container 3 . In the described embodiment, the operating fluid container is designed as a urea container for a liquid urea solution as reducing agent for catalytic denitrification of exhaust gases in motor vehicles.

[0050] The operating fluid container 3 can be formed as a one-piece extrusion blow-molded plastics material container. Filler tube 2 and filler neck 1 may also comprise thermoplastic material. The upper part 10 of the filler neck 1 described with reference to the subsequent figures, as well as the other parts described, can also be produced by...

Abstract

The invention relates to a filler neck for an operating-liquid tank (3) for a motor vehicle. The filler neck (1) comprises a mouth-hole neck (11), into which a nozzle can be inserted in order to fill the operating-liquid tank (3). A ventilation path is provided in the filler neck (1), which ventilation path allows a ventilation flow parallel and oppositely to the filling volumetric flow through the mouth-hole neck (11) during filling. The filler neck (1) according to the invention is characterized in that the ventilation path comprises at least one ventilation channel (18) provided in a wall arrangement (14) of the mouth-hole neck (11), which at least one ventilation channel is at least partially surrounded by an outer wall (14a) and an inner wall (14b) of the wall arrangement (14) along the longitudinal extent of the at least one ventilation channel.

Description

technical field [0001] The present invention relates to a filler neck for a working fluid container of a motor vehicle, wherein the filler neck includes a manhole neck which can be introduced into a dispensing valve member to fill the working fluid, and wherein a filler neck is provided in the filler neck A vent line which, during the filling operation, allows a vent flow parallel to and opposite to the filling volume flow through the manhole neck. Background technique [0002] The working fluid container may be a fuel tank, a plain container used in the SCR (Selective Catalytic Reduction) method, or other automotive working fluid container. [0003] When filling the motor vehicle hydraulic fluid container, for example via the dispensing valve member, the hydraulic fluid can flow out via the filler neck. When the valve is closed through the air hole / shut-off hole in the dispensing valve member, the pressure shock generated in this case causes the amount of fluid to surge an...
