DEVICE FOR THE RECUPERATION OF FUEL VAPOUR WHEN FILLING A FUEL TANK

摘要

A device for trapping fuel vapors during the refuelling of a fuel tank having a vapor control valve and which during refuelling, is moved into an open position provided outside the tank filler pipe safety valve which closes under the influence of gravity due to certain inclined positions of the fuel tank is connected upstream of the control valve, so that no fuel can escape through the vapor vent line in the case of a crash, even if the control valve no longer closes.
