Abstract

Provided is a fuel tank control valve for a vehicle that appropriately and actively controls a loading pipe of an evaporation gas which is connected from a fuel tank to a canister, and prevents internal pressure of the fuel tank from excessively increasing or decreasing, by basically preventing the evaporation gas from being loaded from the fuel tank to the canister when the engine is turned off, allowing the evaporation gas to be loaded from the fuel tank to the canister when the engine is turned on, and allowing the evaporation gas to be loaded from the fuel tank to the canister, even if the engine is turned off, when the vehicle is filled with fuel.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2010-0122044 filed on December 2, 2010, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to a control valve for a fuel tank of a vehicle, and more particularly, the present invention relates to a control valve between the fuel tank and the canister that controls the movement of boil-off gas from the fuel. Background technique [0004] A canister of a vehicle is a device that prevents boil-off gas from fuel from leaking into the atmosphere by collecting boil-off gas from fuel stored in the fuel tank, and discharges boil-off gas to the engine when the engine is operating air intake system for combustion. [0005] Recently, in a hybrid vehicle or a plug-in hybrid vehicle, the operating ratio of the electric motor when the vehicle is running is greatly increased ...
