ABSTRACT:
A stop valve structure that is accommodated in a fuel tank includes a casing, a float disposed inside the casing for reciprocating movement within the casing, a bottom wall defining a lower end of the casing, at least one hole provided along the periphery of the bottom wall, and a valve opening that is selectively opened and closed by the reciprocating movement of the float within the casing in accordance with a liquid fuel level within the casing. The float is provided with a tapered portion at the lower end thereof which becomes smaller in diameter toward the lower end of the casing. The float is further provided with a valve seat in an upper portion thereof. A valve mounting portion is disposed inside the casing and a valve element is mounted to said valve mounting portion. The valve seat cooperates with the valve element to selectively open and close the valve opening. These features ensure the operational stability and smoothness of the stop valve.
