【実用新案登録請求の範囲】[Scope of utility model registration request] 空気圧力を燃料タンク内の燃料液面上方に供給して燃料
ヘッド圧力を高めるようにしたものにおいて、エンジン
のクランクケースと上記燃料タンクの燃料液面上方とを
所要の通路で連通し、かつ久ランクケース内圧が負圧の
時、上記通路を遮断するチェックバルブを上記通路ムこ
配設したことを特徴とする内燃機関の燃料供給装置。In a device that increases the fuel head pressure by supplying air pressure above the fuel liquid level in the fuel tank, the engine crankcase and the fuel tank above the fuel liquid level are communicated through a required passage and the fuel head pressure is increased. 1. A fuel supply device for an internal combustion engine, characterized in that a check valve is disposed in the passageway to shut off the passageway when the internal pressure of the rank case is negative.
