ABSTRACT:
A fuel valve comprises a first valve chamber and a second valve chamber within a casing, where a first valve mechanism and a second valve mechanism are housed in the respective valve chambers. A first float of the first valve mechanism rises when the fuel level reaches a first liquid level, to close a first connection conduit. The second valve mechanism rises to close a second connection conduit when a second liquid level, which is higher than the first liquid level is reached. A valve conduit, which acts as a restriction path, is provided between the first valve chamber and the second valve chamber. The valve conduit is formed with a conduit area that is less than that of the first connection conduit, so as to increase the pressure within the fuel tank when the first connection conduit is closed.
