Title:
FUEL CUTOFF DEVICE FOR FUEL TANK
Document Type and Number:
Japanese Patent JP3535338
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To stabilize the timing of actuating the first automatic stopping function of a fuel cutoff at fuel filling rates at least 95% of the capacity of a fuel tank.
SOLUTION: A casing 1 encloses a float 7, and a valve element A and a valve element B both adapted to move vertically in synchronism with the vertical motion of the float 7 so as to open or close valve seats (a) and (b) individually formed in the end of a feed path 9. The valve elements A and B are coupled together by way of a flange part 8 formed on the element A fitted into a restriction groove 11 cut in the other element B, such that the element A moves vertically before or after the element B. The casing 1 is perforated at its sides with side holes 2 of lower inflow resistance and at its bottom with a bottom hole 12. The casing 1 in integrally formed with a valve casing 15, which encloses a hollow valve element 13 for opening or closing the bottom hole 12 and has an opened bottom. In filling a fuel tank, the hollow valve 13 closes the bottom hole 12 to cause liquid fuel to flow into the casing 1 through the side holes 2, which operation moves the float 7 upward to finally seat the valve elements A and B on the valve seats (a) and (b).
