Vorrichtung zum Verteilen der Verdünstungen für einen Kraftstofftank

摘要

A fuel tank vapour control apparatus controls the flow of liquid and vapour fuel through an aperture in a fuel tank (16). The fuel tank vapour control apparatus includes a vent housing (12) mounted in the aperture (34) and formed to include a vent inlet (13) and a vent outlet (36), the vent housing (12) defining a vent path for communicating vapour fuel from the fuel tank between the vent inlet and the vent outlet. The apparatus also includes a valve (48) movable in the vent housing between a blocking position for blocking flow of liquid and vapour fuel from the fuel tank between the vent inlet and the vent outlet along the vent path and a venting position allowing flow of vapour fuel between the fuel tank and the vent outlet along the vent path. A labyrinthine member (140) is also included, being disposed between the fuel tank and the vent path for discriminating fuel vapour from liquid fuel so as to block liquid fuel from the vent path.
