<p>The valve has three ports (18, 20, 21) provided to a fuel tank or vapor filter, a filling pipe and atmosphere, respectively. The operating exhaust of the tank is effected in a switching position of the valve in which a path is activated between the ports (18, 21). The refueling exhaust of the tank is effected in another position of the valve in which another path is activated between the ports (18, 20) under bypass of another filter.</p> |
