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.
