Definitions
- the present invention relates to a flap valve device and a gas-liquid separation device including the flap valve device, and is applied to, for example, a gas-liquid separation device for removing liquid in fuel vapor flowing from a fuel tank of an automobile to a canister. .
- a fuel tank of an automobile has a fuel vapor passage for discharging fuel vapor to the outside of the fuel tank and a canister that is provided in the fuel vapor passage and adsorbs the fuel vapor in order to suppress an increase in internal pressure.
- the fuel adsorbed by the canister is released from the canister by the intake negative pressure of the intake system, passes through the intake system, and flows into the combustion chamber. In this way, the increase in the internal pressure of the fuel tank is suppressed without releasing the fuel vapor to the outside.
- a configuration in which one end of a fuel vapor passage opens at the upper portion of the fuel tank and this opening is opened and closed by a float valve is known.
- the float valve moves up and down according to the liquid level in the fuel tank, and closes the fuel vapor passage when the liquid level reaches a predetermined value or more, so that the liquid fuel in the fuel tank does not flow into the fuel vapor passage.

- the gas-liquid separator has a normally open flap valve device that is rotatably mounted in the filler pipe and opens and closes the opening at the lower end of the main pipe.
- the flap of the flap valve device is normally in the open position, and when pushed by the oil supply nozzle inserted into the filler pipe during refueling, it moves to the closed position and closes the opening of the main pipe.
- the flap is formed so as to have a gap with the partition wall in a state where the opening of the main pipe is closed.
- the fuel vapor flowing through the fuel vapor passage passes from the top to the bottom through the first passage of the main pipe, passes through the filler pipe, passes through the second passage from the bottom to the top, and flows to the canister. .
- the liquid fuel that has entered the fuel vapor passage flows from the first passage to the filler pipe by gravity and does not reach the canister.
- the fuel supply nozzle pushes the flap in the closing direction to close the opening of the main pipe, and the liquid fuel flowing in the filler pipe does not enter the main pipe.
- the fuel vapor passes through the gap between the partition wall and the flap and flows to the second passage and the canister, and the liquid fuel is collected on the lower end of the main pipe, that is, on the flap.
- the fuel filler nozzle is removed from the fuel filler opening and the flap is opened, the liquid fuel collected on the flap flows into the filler pipe.
