徴とする加圧型気化器用燃料蒸散防止切換弁。A diaphragm is in an inoperative position when the engine is stopped, and is actuated by manifold pressure while the engine is running, and is suctioned and held in the operating position by a solenoid. When the diaphragm is in the operating position, the canister side passage is opened and the air vent side passage is closed.
In a fuel evaporation prevention switching valve for a carburetor, which is equipped with a side passage closed and an air vent side passage opened (valve body), the diaphragm and the valve body are connected via a spring, and turbo pressure acts on the diaphragm. for a pressurized type vaporizer, characterized in that even if the valve body is separated from the solenoid, the valve body continues to be held in a position where the canister side passage is closed and the air vent side passage is closed by the pressure inside the float chamber. Fuel evaporation prevention switching valve.
