PROBLEM TO BE SOLVED: To provide a fuel shut-off valve having desirable characteristics.SOLUTION: A control valve 3 provides a fuel shut-off valve. The control valve 3 provides a valve 11 for opening and closing a ventilation passage of a fuel tank. The control valve 3 is provided with a float 51 for closing the valve 11 by moving in a valve closing direction while floating on fuel, and for opening the valve 11 by moving in a valve opening direction that is opposite to the valve closing direction. The control valve 3 has an auxiliary member 71 having a predetermined weight. The auxiliary member 71 abuts on the float 51 to cause the weight thereof to act on the float 51 in the valve opening direction, or separates from the float 51 not to cause the weight thereof to act on the float 51 in the valve closing direction. The control valve 3 provides a liquid level-sensitive valve that responds to a liquid level of the fuel. The control valve 3 provides a tilt-sensitive valve that responds to a tilt angle of the control valve 3. The auxiliary member 71 acts as a weight in the valve opening direction but does not act as the weight in the valve closing direction. As a result, desirable characteristics are achieved.SELECTED DRAWING: Figure 3

    【課題】望ましい特性もつ燃料遮断弁を提供する。【解決手段】制御弁3は、燃料遮断弁を提供する。制御弁3は、燃料タンクの通気通路を開閉する弁11を提供する。制御弁3は、燃料に浮いて閉弁方向に移動して弁11を閉弁させ、閉弁方向とは逆の開弁方向に移動して弁11を開弁させるフロート51を備える。制御弁3は、所定の重さをもつ補助部材71を有する。補助部材71は、開弁方向へフロート51に重さを作用させるようにフロート51に当接し、閉弁方向へフロート51に重さを作用させないようにフロート51から離れる。制御弁3により、燃料の液面に応答する液面感知弁が提供される。制御弁3により、制御弁3の傾斜角に応答する傾斜感知弁が提供される。補助部材71が、開弁方向へは錘として作用し、閉弁方向へは錘として作用しない。このため、望ましい特性が実現される。【選択図】図3
