Abstract
A canister close valve device for opening or closing a passage provided between a canister, which collects evaporation gas evaporated from a fuel tank and the atmosphere may include a plunger configured to selectively move up or down through magnetization with a core inside a valve housing when a solenoid is activated, a rod configured to perform a rectilinear reciprocating movement toward or away from the passage due to the upward/downward movement of the plunger, and a diaphragm valve body, which is inserted into the plunger, is connected to the valve housing, and is configured to be deformed by the upward/downward movement of the plunger and to generate force for impeding the upward/downward movement of the plunger using a pressure difference generated between the plunger and the valve housing.
