Fuel cap with poppet type valves |
摘要 |
A fuel cap has a pair of poppet type valves which control the pressure level within the fuel tank. Each valve member has a seat portion and a valve stem guide portion formed integral with the threaded closure member of the cap. A conical valve member having a longitudinally extending stem is positioned on the valve seat and in the stem guide by a spring member. The valve which controls the maximum pressure within the fuel tank is operable to permit very high gas flow rates.
