FUEL TANK

摘要

Fuel tank with a collecting device arranged in its filler inlet for collecting fuel vapours when refuelling. …On a known collecting device an automatically closing control valve is built into the filler inlet above the maximum fuel level, which valve is located between a fuel vapour line leading from the fuel tank to an activated charcoal filter and opens this line as soon as the petrol pump filling nozzle is introduced into the filler inlet. The control valve is mechanically opened by a sealing flap which closes a guide duct inside the filler inlet receiving the filling nozzle when the flap is swung into its open position by the filling nozzle, thereby switching a valve element of the control valve into its open position. …The collecting device according to the invention is intended to simplify both the construction of the control valve and the means needed for its actuation. This is achieved in that the sealing flap at the same time forms the valve element of the control valve. ……
