Claims (1)
路の一側にエンジンのクランク室、又はエンジンと気化
器との間に介設されるインシュレーターパイプの内圧に
より脈動するダイヤフラムを配して成る真空式燃料ポン
プにおいて、前記両バルブ間の燃料通路の両側に夫々前
記ダイヤフラムを対向させて配置したことを特徴とする
真空式燃料ポンプ。It is equipped with an intake valve and a discharge valve, and on one side of the fuel passage between the two valves is arranged a diaphragm that pulsates due to the internal pressure of the engine crank chamber or an insulator pipe interposed between the engine and the carburetor. A vacuum fuel pump characterized in that the diaphragms are disposed facing each other on both sides of the fuel passage between the two valves.
