AN INLET CHECK VALVE FOR A FILLER PIPE WELDED TO A LIQUID TANK

An inlet check valve intended to be entirely located within an internal volume delimited by a liquid tank of a vehicle and a filler pipe welded to the tank, the filler pipe defining a downstream direction, followed by a liquid filling the tank, and an upstream direction opposite to the downstream direction, the inlet check valve comprising a tube with an upstream end pointing toward the upstream direction and, at the upstream end, resilient means for adapting the form of the tube to the internal wall of the filler pipe, wherein the inlet check valve comprises hook means for securing the tube to an internal wall of the filler pipe and prevent the inlet check valve from moving within the filler pipe in the downstream direction.
