Filler inlet for a fuel tank, particularly for motor vehicles

摘要

A fuel filler neck with a vent device is provided for receiving fuel from a dispensing pistol and depositing the fuel into a fuel tank, which fuel filler neck simultaneously allows for optimal utilization of the fuel tank volume and for operationally adequate venting during refueling. The filler neck is formed in one piece with the vent device having a cross-sectional enlargement forming an expansion space. A connecting duct is provided at the area where the expansion space opens into the filler neck and a discharge gap is provided at the area where the vent device enters the filler neck.
