Abstract

PURPOSE:To simplify the structure of a valve system by forming a rotary valve into its cylindrical shape in such a manner as forming it with its exhaust part and intake part formed by holes opened in bottom faces on its both sides and holes opened its side surface respectively connected to each other. CONSTITUTION:In order to obtain a rotary valve, exhaust ports 1 and intake ports 2 are respectively formed in a cylindrical valve main body by connecting respective holes, formed in both end surfaces of the cylinder to respective holes formed in the side surface of the cylinder. By giving both exhaust port 1 and intake port 2 to one valve like this, the number of valves for one cylinder can be cut down to one. In addition, it becomes possible by switching the valve by turning it that rotary motion of a crank shaft can be transferred to the valve without converting the rotary motion into reciprocating motion, thereby obtaining smooth operation of the valve.

トも高価になっていた。Prior Art In conventional internal combustion piston engines, the valves used for intake and exhaust from the combustion chamber are divided into intake valves and exhaust valves.
More than two valves were required per cylinder. The opening and closing of these valves is an unsmooth reciprocating motion, and in order to convert the rotational motion of the crankshaft into reciprocating motion of the valve, a complex valve mechanism consisting of many parts such as cams is used, which reduces production costs. It was getting expensive.

に作動させる。Means for Solving the Problem By providing a single valve with an exhaust port ( ) and an intake port (2), it is possible to reduce the number of valves to -per cylinder by rotating the valve. By doing so, the rotational motion of the crankshaft is transmitted to the valve without being converted into reciprocating motion, allowing the valve to operate smoothly.

作用シリンダーに対して、垂直方向に回転弁を組み込み回転させた、作動中の内燃機関のピストン
機関を説明する。A piston engine of an internal combustion engine in operation will be described in which a rotary valve is installed and rotated in a vertical direction with respect to a working cylinder.

第２図のように、排気ガスの排気行程では、回転弁の排気口（１）が燃焼室（６）に向いてお
り排気が行われる。As shown in FIG. 2, in the exhaust stroke of the exhaust gas, the exhaust port (1) of the rotary valve faces the combustion chamber (6), and the exhaust gas is exhausted.

第３図の混合気の吸気行程では、回転弁の吸気口（２）が燃焼室（６〉に向いており吸気が行
われる。In the intake stroke of the air-fuel mixture shown in FIG. 3, the intake port (2) of the rotary valve faces the combustion chamber (6>), and intake is performed.

第４図の圧縮行程から膨張行程の間では、回転弁の穴の無い側面が、燃焼室（６〉に向いてい
るなめ、回転弁は閉じられていることになる。Between the compression stroke and the expansion stroke in FIG. 4, the side surface of the rotary valve without holes faces the combustion chamber (6>), so the rotary valve is closed.
