  • Patent number: 11511620
    Abstract: A ventilation control valve for a fuel tank is disposed in a ventilation passage which communicates an inside and an outside of a fuel tank. The ventilation control valve includes a float that floats on a liquid level of a fuel and moves up and down. The ventilation control valve includes a valve mechanism which switches a passage sectional area of the ventilation passage in conjunction with the float to an open state and a restricted state in which the passage sectional area is restricted from the opened state. The float has a volume chamber in which volume changes in accordance with a vertical movement of the float. A control gap as a flow rate adjusting mechanism is formed between the cylindrical wall of the float and the cylindrical wall of a case. Due to the control gap, the volume chamber functions as a damper.

  • Patent number: 10967733
    Abstract: A fuel shutoff valve includes a valve, a float, and an auxiliary member. The valve is configured to open or close an air passage of a fuel tank. The float floats on fuel and moves in a valve closing direction to close the valve, or in a valve opening direction opposite to the valve closing direction to open the valve. The auxiliary member has a predetermined weight, and abuts on the float to apply a weight on the float in the valve opening direction, or separating from the float not to apply the weight on the float in the valve closing direction.
