Abstract

PURPOSE:To reduce the flow resistance of the intake and exhaust by making a valve that opens and closes the intake or exhaust port in a rotary valve configuration. CONSTITUTION:A cylindrical rotary valve 1 having a passageway for intake or exhaust is disposed in the intake or exhaust port. The cylindrical rotary valve 1 has an arm 2, and opens and closes the intake or exhaust port by the movement of the arm 2 in response to a cam 3. As there is no hindrance like a lift valve to the flow of the intake or exhaust, the flow resistance can be reduced.

Description

【発明の詳細な説明】 この発明は、カムを使って回転弁などを反復運動させる
原動機に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a prime mover that repeatedly moves a rotary valve or the like using a cam.

従来、原動機の弁には閉じた時ヘッドにｆＭ定されるキ
ノコ型往復弁が付いていた。その場合、弁の開閉面積は
限られ、しかも弁自体がガスの流れの抵抗物となり、吸
排気抵抗に及ばす害は多かった。又、回転弁は爆発時も
回転しているハ気密性　及び耐久性が悪かった。Conventionally, prime mover valves have had mushroom-shaped reciprocating valves that are fixed at fM in the head when closed. In this case, the opening/closing area of the valve is limited, and the valve itself acts as a resistance to the flow of gas, which has many negative effects on intake and exhaust resistance. In addition, the rotary valve was still rotating during an explosion, so its airtightness and durability were poor.

本発明は、そｎらの欠点を除くために発明されたもので
、これを図面について説明すれば、筒状カム３を介して
、反復させるものである。したかって、一定の所を爆発
時は固定され、吸排気時には元に　もどる　ものである
。そして、セラミック材などを使用すれはシール６によ
る気密も向上するものである。The present invention was invented to eliminate these drawbacks, and if this is explained with reference to the drawings, it is repeated through the cylindrical cam 3. Therefore, a certain point is fixed during explosion, and returns to its original position during intake and exhaust. If a ceramic material or the like is used, the airtightness of the seal 6 will also be improved.

本発明は、このように従来の流れを害する弁を一変させ
た好都合な原動機の弁であろうThe present invention may thus be an advantageous prime mover valve that revolutionizes conventional flow-impairing valves.
