Fuel tank venting |
摘要 |
A fuel tank has a filler neck terminating in an upwardly opening well, and a paddle overlying the well has a pivoted arm extending adjacent a vent valve. The arm causes the valve to restrict flow through a vent orifice when fuel is not being introduced through the filler neck, but pivots to allow the valve to open the orifice in response to introduction of liquid fuel through the filler neck. A float has an actuating member adapted to cause the valve to restrict flow through the orifice when the level of liquid fuel in the tank approaches the maximum level desired.
