【実用新案登録請求の範囲】[Scope of utility model registration request] 各気筒の吸気通路にスロットルバルブを有するエンジン
の負圧供給装置において、吸気バルブのステムの中央に
設けられ、開弁時のみ一部がシリンダヘッドの吸気ポー
トと連絡する溝と、該溝と導通し、シリンダヘッド内に
気筒毎に設けられた負圧通路と、該負圧通路をお互い連
通ずる供給通路と、該供給通路に備えられた負圧取出口
とから成ることを特徴とするエンジン負圧供給装置。In a negative pressure supply device for an engine that has a throttle valve in the intake passage of each cylinder, there is a groove provided in the center of the stem of the intake valve, a part of which communicates with the intake port of the cylinder head only when the valve is open, and conduction with the groove. The negative pressure engine comprises a negative pressure passage provided for each cylinder in a cylinder head, a supply passage communicating the negative pressure passages with each other, and a negative pressure outlet provided in the supply passage. Pressure supply device.
