Abstract
【課題】エンジン燃焼室への吸気及び排気の効率を向上させ、また部品点数の減少及び重量の軽量化をなしたエンジンの回転式吸排気バブルを提供する。
【解決手段】エンジン燃焼室を含むヘッド本体の上部に吸気口及び排気口を兼ねた吸気兼排気口を設けた回転板を設置し回転板を回転させることにより、回転板の吸気兼排気口と燃焼室吸気ポートが重なった時に吸気、回転板の吸気兼排気口と燃焼室排気ポートが重なった時に排気を行うことにより効率を向上させる、又構造が簡単で部品点数も少ないので重量を軽くすることが可能である。
【選択図】図２A rotary intake / exhaust bubble for an engine that improves the efficiency of intake and exhaust into an engine combustion chamber, reduces the number of parts, and reduces the weight.
A rotary plate provided with an intake / exhaust port that also serves as an intake port and an exhaust port is installed on the upper portion of the head body including the engine combustion chamber, and the rotary plate is rotated to rotate the intake / exhaust port of the rotary plate. Efficiency is improved by performing intake when the combustion chamber intake port overlaps, and exhausting when the intake / exhaust port of the rotating plate and the combustion chamber exhaust port overlap, and the weight is reduced because the structure is simple and the number of parts is small. It is possible.

Description
本考案は、エンジン燃焼室の吸気及び排気バルブに関するものである。The present invention relates to an intake and exhaust valve for an engine combustion chamber.
４サイクルエンジンの吸気及び排気はバルブが上下運動することによりバルブの開閉を行う。The intake and exhaust of the 4-cycle engine opens and closes the valve as the valve moves up and down.
バルブの上下運動で行われる吸気及び排気では、燃焼室とバルブの隙間で吸気及び排気が行われる為効率が良くなく、効率を良くする為にはバルブの数を増やすなどするので、エンジンが複雑になり又エンジンの重量も増加する。The intake and exhaust performed by the vertical movement of the valve is not efficient because the intake and exhaust are performed in the gap between the combustion chamber and the valve, and the number of valves is increased to improve the efficiency. In addition, the weight of the engine increases.
本考案は、エンジン燃焼室を含むヘッド本体の上部に吸気口及び排気口を兼ねた吸気兼排気口を設けた回転板を設置し回転板を回転させることにより、回転板の吸気兼排気口と燃焼室吸気ポートが重なった時に吸気、回転板の吸気兼排気口と燃焼室排気ポートが重なった時に排気を行うことにより効率を向上させる、又構造が簡単で部品点数も少ないので重量を軽くすることが可能なので問題点を解決している。In the present invention, a rotary plate provided with an intake / exhaust port that also serves as an intake port and an exhaust port is installed on the upper part of the head body including the engine combustion chamber, and the rotary plate is rotated to thereby rotate the intake / exhaust port of the rotary plate. Efficiency is improved by performing intake when the combustion chamber intake port overlaps, and exhausting when the intake / exhaust port of the rotating plate and the combustion chamber exhaust port overlap, and the weight is reduced because the structure is simple and the number of parts is small. It is possible to solve the problem.
上述の様に、本考案は吸気及び排気の効率を良くすることは勿論、部品点数が少ない為構造を簡単にすることが出来、重量を軽くすることが可能である。As described above, the present invention not only improves the efficiency of intake and exhaust, but also has a small number of parts, so that the structure can be simplified and the weight can be reduced.
燃焼室を含むエンジンヘッド本体の上部に吸気口及び排気口を兼ねる吸気兼排気口を設けた回転板を設置する。回転板を回転させることにより、回転板に設けられた吸気兼排気口と燃焼室の吸気ポートが重なった時に吸気を、回転板に設けられた吸気兼排気口と燃焼室の排気ポートが重なった時に排気が行われる。A rotating plate provided with an intake / exhaust port that doubles as an intake port and an exhaust port is installed on the upper part of the engine head body including the combustion chamber. By rotating the rotating plate, the intake / exhaust port provided in the rotating plate and the intake port of the combustion chamber overlap, and the intake / exhaust port provided in the rotating plate and the exhaust port of the combustion chamber overlap. Sometimes exhaust occurs.
以下、添付図面に従って一実施例を説明する。燃焼室を含むエンジンヘッド本体７の上部に吸気兼排気口４を設けている回転板１を設置。回転板１を燃焼室８との同心円状に時計方向に回転させ、吸気兼排気口４と燃焼室吸気ポート５が重なった時に吸気を、吸気兼排気口４と燃焼室排気ポート６が重なった時に排気が行われる。Hereinafter, an embodiment will be described with reference to the accompanying drawings. A
