Abstract
A fuel vapor control device has a flow control valve which regulates a flow amount of fuel vapor from a fuel tank to a canister. The flow control valve has a movable element accommodated in a case. The movable valve element has a central cylindrical part, an outer cylindrical part, and a disc part which connects the central cylindrical part and the outer cylindrical part. The central cylindrical part provides a central channel. The central channel provides a main channel which communicates an inlet and an outlet. A sub channel defined and formed between the movable element and the case is opened and closed by a valve formed by the case and the outer cylindrical part. The central channel makes easy setting of flow amount in regulated condition. Since turbulence is reduced, it is possible to perform stable regulation.
