Description
【発明の詳細な説明】 本発明は往復動機関の給、排気弁に関する。[Detailed description of the invention] The present invention relates to supply and exhaust valves for reciprocating engines.
第１図は従来の往復動機関の要部を示す断面図である。FIG. 1 is a sectional view showing the main parts of a conventional reciprocating engine.
図において、１，２は弁ばね、３．ａｌｌ。In the figure, 1 and 2 are valve springs; 3. all.
カム、５，６はカム駆動ギア、７は点火ゾラク゛穴。The cam, 5 and 6 are cam drive gears, and 7 is the ignition hole.
８は排気弁、９は給気弁、１０はピストン、１１はシリ
ンダを示す。8 is an exhaust valve, 9 is an air supply valve, 10 is a piston, and 11 is a cylinder.

気効率が低下する。Air supply valve9. Conventionally, the exhaust valve 8 has a circular shape, that is, the periphery of the umbrella part is circular, and the air supply valve 13. It was designed to open at right angles to the exhaust port 12. By opening at right angles, the air supply efficiency decreases as the air supply flow approaches the intake valve blade 15°R11 and the valve umbrella, and the scavenge air flow also approaches the JJ1 valve blade 14, resulting in a decrease in exhaust efficiency.
これに往復動機関の効率の低下の一因ともなっている。This is also one of the causes of a decrease in the efficiency of reciprocating engines.
本発明の目的は上記の点に着目し、給気効率及び抽気効
率をそれぞれ向上できる給、排気弁を提供することであ
シ、その特徴とするところは、傘部の周縁が楕円状に形
成され弁軸方向の変位に連動して所定角度回動すること
である。An object of the present invention is to focus on the above points and provide a supply and exhaust valve that can improve air supply efficiency and air extraction efficiency, and is characterized in that the peripheral edge of the umbrella part is formed in an elliptical shape. The valve shaft rotates by a predetermined angle in conjunction with the displacement in the valve shaft direction.
この場合は、楕円形の弁が開放するに従って給気１−］
、 ＩＬＩＩ気口に対して回動し気室内に流出入する
気流が弁のブレードに肖らないようにして、給。In this case, as the oval valve opens, the air supply 1-]
, rotates relative to the ILII air port to prevent the airflow flowing in and out of the air chamber from being exposed to the blade of the valve.
４Ｊ１気弁ブレードに当らない給、排気流が増加するこ
とによシ、給、排気効率が向上し、往復動機関の出力及
び経済性が向上する。By increasing the supply and exhaust flow that does not hit the 4J1 air valve blades, the supply and exhaust efficiency is improved, and the output and economy of the reciprocating engine are improved.
本発明は４サイクル、２サイクル内燃機関、ポンプ、コ
ンプレッサに適用できる。The present invention is applicable to four-stroke and two-stroke internal combustion engines, pumps, and compressors.
以下図面を参照して本発明による実施例につき説明する
。Embodiments of the present invention will be described below with reference to the drawings.
第２図は本発明によるＪ実施例を示す第１図のＡ部分図
である。FIG. 2 is a partial view of A in FIG. 1 showing the J embodiment of the present invention.
図において、１６は弁駆動カム、１７は弁ばね。In the figure, 16 is a valve drive cam, and 17 is a valve spring.
１８は給気弁１９が１往復する間に弁軸を角度α回転さ

置状に形成されている。２０は給気口を示す。なお、排
気弁も同じ構造である。Reference numeral 18 denotes a screw for rotating the valve shaft by an angle α during one reciprocation of the air supply valve 19, and the air supply valve 19 has an inverted shape at the periphery of its umbrella portion. 20 indicates an air supply port. Note that the exhaust valve also has the same structure.
上記構成の場合の作用について述べる。The operation in the case of the above configuration will be described.
第３図において、給気弁１９が下がるに頁って。In FIG. 3, the air supply valve 19 is lowered.
給気効率が最適となる角度αまで給気弁１９が弁の軸心
まわ、！２に回転する。なお、第３図において２（１）

ぞれ示す。The air supply valve 19 is rotated around the axis of the valve until the angle α where the air supply efficiency is optimal! Rotate to 2. In addition, in Figure 3, 2(1)
1 shows the closed state, (2) shows the open state, and (3) shows the open state.
上述の場合には次の効果がある。The above case has the following effects.
給気弁１９が回転することにより、給気流が給気弁１９

が向上し、内燃機関に応用される場合は、出力の向上、
経済性の向上が実現でき、ポンプやコンプレッサに応用
される場合は、効率の向上が実現できる。By rotating the air supply valve 19, the air supply flow is caused by the rotation of the air supply valve 19.
When applied to internal combustion engines, it improves output, reduces the amount of interference caused by the valve blades, and improves air supply efficiency.
Improved economy can be achieved, and when applied to pumps and compressors, improved efficiency can be achieved.
この構造の回転楕円弁は排気弁にも同様の効果をもたら
し、排気効率を向上させる。The spheroidal valve with this structure has a similar effect on the exhaust valve, improving exhaust efficiency.
