Document Type and Number:
Japanese Patent JP3692323
Kind Code:
B2
Abstract:
A safety valve, such as for a refueling vent line between the tank filler neck and the active charcoal container in a motor vehicle. The safety valve is inserted into the refueling vent line being configured as a float valve. When fuel penetrates into the refueling vent line, and thereby into the safety valve, the outlet of the safety valve is closed by the float. The safety valve is provided with an anti-pollution pipe-end opening onto the environment and closed at normal pressure by a closure operated by a diaphragm. At an elevated pressure in the safety valve, the diaphragm effects an opening of the closure at the anti-pollution pipe-end.
