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.
Claims8
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 coupled to said housing and operable between a closed position closing said orifice of said tubular port and an open position opening said orifice to allow fluid into the fuel tank;
- an actuating mechanism operatively coupled between said housing and said shutter for actuating and biasing said shutter from said open position to said closed position, said actuating mechanism including a lever pivotally coupled to said housing and cooperative with said shutter for automatically moving said shutter from said open position to said closed position and a damping device operatively coupled to said lever for delaying said automatic movement of said shutter from said open position to said closed position upon removal of a fuel pump nozzle from said tubular port thereby allow any residual fuel from the nozzle to enter said orifice prior to said shutter reaching said closed position.
