摘要： PURPOSE:To enable simplification and reduction in the weight of a driving mechanism, by a method wherein a crank shaft and the shaft of a rotary valve are intercoupled through a timing belt which runs in a solid manner through idlers. CONSTITUTION:A suction rotary valve 9, which controls opening and closing of a suction passage 8, is located to the rear of a cylinder 1 and above a crank case 5. A pulley 12, mounted on a crank shaft 6, and a pulley 11 of a rotary valve shaft 10 are intercoupled through a timing belt 13 which runs in a solid manner around the pulleys through the medium of idlers 15 and 16. This eliminates a bevel gear and enables simplification and a decrease in the weight of a driving mechanism and also reduces the generation of noise.

摘要： PURPOSE:To reduce loss power by operating a valve by a cam fitted onto a crank shaft and reducing the pressure in a crank chamber. CONSTITUTION:When a piston E lowers, a cam A fitted onto a crank shaft B turns, and a valve D is shifted, and the pressure in the crank chamber reduces. When a piston E reaches bottom dead center, the cam A shifts a connecting rod C, and the valve D is shifted, and the mixed gas is supplied into a cylinder from a scavenging hole. When the piston lowers, the loss power reduces, since the inside of the crank chamber is decompressed.
摘要翻译：目的：通过使用安装在曲轴上的凸轮操作阀门并降低曲轴箱内的压力来减少损失功率。构成：当活塞E下降时，安装在曲轴B上的凸轮A转动，并且阀D偏移，曲柄室内的压力降低。当活塞E到达下死点时，凸轮A移动连杆C，并且阀D移动，并且混合气体从扫气孔供给到气缸中。当活塞降低时，由于曲柄室的内部被减压，损失功率降低。

摘要： PURPOSE:To make an engine power most suitable by regulating the exhaust valve in timing by a method wherein a governor mechanism for operating the exhaust valve is provided at one end of a crank shaft, and a water pump is fitted at the pointed end of the governor shaft. CONSTITUTION:A cylinder 1 of the engine has a piston 3, and the governor mechanism 7 for operating the exhaust valve is fitted on one end of the crank shaft 5. The governor shaft 8 at the pointed end is fitted with the water pump 26. Accompanying the rotation of the crank shaft 5, a ball 12 is directed outward due to a centrifugal force and operates the exhaust valve 21 through a slider 10, a shift fork 16, a shaft lever 7, a lever 18, an adjust bolt 24 and a holder 22. The ball 12 works on the exhaust valve 21 to be driven quickly at the high-speed operation, and driven slowly at the low-speed operation. Thus, the exhaust timing can be regulated to make the engine power most suitable.

摘要： PURPOSE:To form the cylinder wall of an engine into a relatively small thickness and simplify its construction, at a part where a valve for changing the exhaust timing is provided. CONSTITUTION:A recess 11 is formed corresponding to the top edge part of an exhaust port 10 in a cylinder 1, a valve 13 is provided therein. In accordance with a rotational speed of the engine an operating shaft 19 is rotated, and the valve 13 is shifted along an axial direction of the cylinder 1 through an operating arm 22, link member 24 and sliding rod 14 to change a height of the opening port of the exhaust hole 10 thus to change the exhaust timing. Said valve 13 being shifted along the axial direction of the cylinder 1, its width in a diametric direction of the cylinder 1 is only required to have a dimension enough for obtaining the necessary strength, thus the wall of the cylinder 1 can be made relatively thin in its thickness, and its construction can be simplified.
