Abstract

To solve a problem that, in a conventional intake/exhaust valve of a four-cycle gasoline engine or the like, a mechanism becomes complicated because it is opened and closed by a vertical motion, and a cylinder head becomes large in a size, thus causing the generation of vibration and noise, and when opening and closing the intake/exhaust valve, particularly when opening it, an engine output is largely used because the sprung valve is pressed down, thus causing a large loss.SOLUTION: Since a rotary intake/exhaust valve of a four-cycle gasoline engine or the like can control air intake, air exhaust and closure by rotating and stopping a circular columnar shaft in which a hole for air intake and air exhaust is opened, and has a mechanism for rotating the shaft, an engine can be reduced in a size, a loss of an output is reduced to the minimum, and vibration and noise can be minimized.SELECTED DRAWING: Figure 1

Description

この発明は、吸気、排気のための孔が開いた円柱形のシャフトを回転、停止させ、吸気、排気、閉鎖をコントロールするシャフト回転式エンジン吸気、排気バルブに関するものである。  The present invention relates to a rotary shaft engine intake and exhaust valve that controls intake, exhaust, and closure by rotating and stopping a cylindrical shaft having holes for intake and exhaust.

従来、４サイクルガソリンエンジン等の吸気、排気バルブは、縦運動により開閉していたが、本発明では、吸気、排気のための穴が開いたシャフトを回転、停止させることにより吸気、排気、閉鎖をするバルブである。  Conventionally, intake and exhaust valves of a 4-cycle gasoline engine or the like have been opened and closed by vertical movement, but in the present invention, intake, exhaust, and closure are performed by rotating and stopping a shaft having holes for intake and exhaust. It is a valve that does.

従来の４サイクルガソリンエンジン等の吸気、排気バルブは、縦運動により開閉するため機構が複雑であり、シリンダーヘッドも大きくなり、振動、騒音も発生する要因であった。
また、吸気、排気バルブを開閉、特に開く際は、バネが効いたバルブを押し下げることからエンジン出力を大きく利用し、大きなロスが生じていた。
本発明は、以上のような欠点をなくし、吸気、排気のための穴が開いたシャフトを回転、停止運動させ、吸気、排気、閉鎖をコントロールすることができ、シャフトを回転運動させる機構であることからエンジンを小型軽量化化し、出力のロスを 少なくし、振動、騒音も最小にするものである。The intake and exhaust valves of a conventional 4-cycle gasoline engine etc. are opened and closed by vertical movement, so the mechanism is complicated, the cylinder head becomes large, and vibration and noise are also generated.
Also, when opening and closing, especially opening the intake and exhaust valves, the spring-loaded valve is pushed down, and the engine output is used greatly, resulting in a large loss.
The present invention eliminates the drawbacks described above, and rotates and stops the shaft with holes for intake and exhaust, and controls the intake, exhaust and closure, and is a mechanism for rotating the shaft. As a result, the engine is reduced in size and weight, output loss is reduced, and vibration and noise are minimized.

発明を解決するための手段Means for Solving the Invention

吸気、排気のための穴が開いたシャフトを回転、停止運動させ、吸気、排気、閉鎖をコントロールすることができる。  A shaft with holes for intake and exhaust can be rotated and stopped to control intake, exhaust, and closure.

発明の効果Effect of the invention

シャフトを回転運動させる機構であるこからエンジン出力のロスを少なくし、振動、騒音も最小にするものである。  The mechanism that rotates the shaft reduces the engine output loss and minimizes vibration and noise.
