摘要 |
A fuel vapor treating apparatus includes a lower valve casing and an upper valve casing. A float is provided in the lower valve casing and a valve portion is provided in the float for sealing the flow of fuel. A valve port is provided between the lower valve casing and the upper valve casing and is opened and closed by the valve portion. A vent passage portion is provided in the upper valve casing. A space portion is provided between the vent passage portion and the valve port. A valve portion of the float moves vertically in accordance with a liquid level in a fuel tank and opens and closes the valve port, whereby the fuel tank is brought into communication with the vent passage portion. A vent port is provided in a partition that separates the space portion from the vent passage portion. And, a second float is provided to open and close the vent port. The fuel vapor treating apparatus reliably stops fuel leakage from the fuel tank.
