Benefits of technology

0003] The disadvantages of the prior art may be overcome by providing a filler neck for the fuel tank of a motor vehicle comprising a housing having a tubular port defining an orifice in fluid communication with the fuel tank of the vehicle. A shutter is coupled to the housing and operable between a closed position closing the orifice of the tubular port and an open position opening the orifice to allow fluid into the fuel tank. An actuating mechanism is operatively coupled between the housing and the shutter for actuating and biasing the shutter from

Embodiment Construction

[0016] The Figures of the drawings illustrate only those parts of the filler neck which are important for the functioning and understanding of the present invention. It is pointed out that the other components which are not illustrated may be designed, in particular, according to the embodiment of a filler neck illustrated in FIGS. 1-6 of WO 99 / 03697. The following description also refers at some points to WO 99 / 03697, which is incorporated by reference herein in its entirety.

[0017] Referring to FIGS. 1 and 2, a filler neck for a fuel tank of a motor vehicle is generally illustrated at 16 including an outer housing 1, shown only partially here, on which an outer flap can be mounted so as to cover the filler neck 16 from outside ambient air. The configuration and arrangement of the outer flap may be similar to those according to FIGS. 3 and 4 of WO 99 / 03697. When the fuel tank of the vehicle is being filled, this outer flap is opened, and, after filling up, is closed again.

Abstract

A filler neck for the fuel tank of a motor vehicle with a shutter which is mounted inside the filler neck and which can be actuated by the pump nozzle into an open position for filling the fuel tank and into a closed position via an actuating mechanism. The actuating mechanism of the shutter cooperates with a damping device during the closing movement in such a way that the shutter can be closed with a time delay.

Description

[0001] The invention relates to a filler neck for a fuel tank of a motor vehicle. More particularly, the invention relates to a filler neck with a shutter which is mounted inside the filler neck and can be brought by a pump nozzle into an open position for filling the fuel tank and into a closed position via an actuating mechanism for closing the filler neck.BACKGROUND OF INVENTION[0002] A filler neck for a fuel tank of a motor vehicle is known, for example, from WO 99 / 03697. In this filler neck, an internally mounted shutter is provided, which replaces the generally conventional tank caps capable of being either screwed on or attached via a bayonet fastening from outside to the filler neck of the fuel tank. The shutter, when in a closed position, ensures a gas-tight and liquid-tight seal between the fuel tank on one side and the ambient air on the other side. An actuating mechanism operates in such a way that the shutter is immediately closed as soon as a fuel pump nozzle has been ...
