    • PROBLEM TO BE SOLVED: To provide a fuel shut-off valve properly adaptable to requirements for fuel tanks having various shapes.
      SOLUTION: The fuel shut-off valve includes a case having a first opening on the lower side in communication with the inside of the fuel tank and a second opening on the upper side in communication with a canister, and having a horizontal hole on the lateral side, a lower float provided in a space of the case in an up-and-down movable manner and having a first valve on the upper side, an upper float provided on the upper part of the lower float in an up-and-down movable manner and having a third opening in communication with a second valve and the canister, a first valve seat provided on the upper float whose third opening is closed when the first valve abuts thereon, and a second valve seat provided near the second opening which is closed when the second valve abuts thereon. A valve member is provided for opening/closing the horizontal hole in linkage with the lower float or the upper float. The valve member opens/closes the horizontal hole depending on the position of the lower float or the upper float so that the horizontal hole has an opening area smaller when closed than when opened.

    • PROBLEM TO BE SOLVED: To provide a fuel flow prevention valve capable of preventing fuel from flowing to a canister before a valve element contacts with a valve seat by restraining the fluidization of the fuel generated at the time of start, stop or turn and flowing in a fuel flow prevention valve.
      SOLUTION: This fuel flow prevention valve has a casing at least one part of which is positioned in a fuel tank, a float provided in a space in the casing movably upward and downward, a valve element provided at a top of the float and contacting with a valve seat formed on the casing, and a ventilation hole formed at the casing and making the space communicate with the fuel tank. In this valve, a top wall is formed on the inner periphery of the casing and on the outer periphery of the float so as to make the fuel entering from the ventilation hole collide with the top wall.
