種のエンジンには、ピストン及びシリンダ間の気密性を
達成する上での重要な問題、並びに摩耗率及び破損率が
極めて高いという問題がある。Conventional piston-actuated combustion engines typically include a set of pistons, each moving within a cylinder, connected to a crankshaft via a connecting rod. In order to reduce the size of piston engines while maintaining their performance and efficiency, engines containing rotating pistons have been proposed. A representative example of this is the Wankel engine. However, this type of engine suffers from significant problems in achieving airtightness between the piston and cylinder, as well as extremely high wear and breakage rates.

ストンエンジンを製造するための新規の構造を提供する
ことにある。The object of the present invention is that the various parts of the engine are arranged in perfect dynamic balance, and that there is no frictional force between the piston and cylinder (I' caused by the pressure of the packing means against the cylinder wall). Provides a new structure for producing a relatively small piston engine (compared to conventional piston engines), in which the necessary airtightness is completely maintained between the piston and cylinder (excluding 2f?i). It's about doing.
以下、添付図面に基づき本発明をより詳細に説明する。Hereinafter, the present invention will be explained in more detail based on the accompanying drawings.

は、軸線Ｃを中心にしてクランク軸２３と共に回転する
。クランク軸２３自体は軸線りを中心に回転する。The new engine shown in FIGS. 1 to 3 includes a rotating cylinder 21, a pair of pistons 22, and a crankshaft 23. The cylinder 21 is a zero rotation cylinder axis t! that rotates clockwise around the axis B at a constant angular velocity! a pair of pistons 22 moving along E and rotating with this cylinder;
rotates about the axis C together with the crankshaft 23. The crankshaft 23 itself rotates around its axis.

is equal to the distance between the axes 1iB and 0, i.e. B
It is designed so that D=CD. Therefore, 〇C=2i DBC to the dog. This means that the angular velocity of the crankshaft 23 about the axis B is exactly twice the angular velocity of the rotating cylinder 21 about the axis B. In order to avoid v1 failure, the rotating cylinder 21 and the crankshaft 23 are connected by a set of gears or any other means.

繰り返される。When the piston 5 reaches its top dead center, the cylinder opening 6 always coincides with the exhaust port 15. The combusted air flows from these two openings toward the exhaust pipe 16 and exits from there. When the engine continues to rotate clockwise and the opening 6 comes to a position facing the intake port 13, compressed air flowing from the compressor 10 via the intake port 14 flows into the cylinder 4. As the engine continues to rotate, the cylinder is sealed and the air inside is compressed. When the engine reaches the top dead center (piston position 1), fuel is ejected from the inductor 11, the air-fuel mixture is ignited while the engine continues to rotate, and the pressure of the combustion air acts on the piston. As a result, the crankshaft 9 and the cylinder casing 8 are driven. At the end of this cycle, the cylinder returns to the exhaust port 15 and the process is repeated.
