摘要： PURPOSE:To prevent the trouble due to the failure to return a lever by turning an air-escape opening/closing route from an air-escape position to a fuel-opened position by the effect of a cam and pushing a push member to the cam surface by a return spring. CONSTITUTION:A main body 1 is provided with a rod-inserting hole 19 in parallel with a valve axis, and a push rod 28 is inserted to be pushed on a cam surface 25. When a collar 16 is brought to an air-escape position, the collar 16 is turned in the direction of an arrow G by the cam effect of a return spring 29 and a thread part 25a. This construction prevents the failure to return the lever 15, thus preventing the trouble of engine beforehand.

摘要： PURPOSE:To prevent the trouble due to the failure to return a lever by turning a collar of the lever from an opening position of an air-escaped opening/closing route to a closed position of the fuel-opened state by the portion of relative play of the collar against a valve by a return spring. CONSTITUTION:A torsion return spring 25 is provided between the bottom of a collar 16 made in one body with a lever 15 and a parallel valve 13 for giving force in the reverse direction of an arrow F. The collar 16 and the parallel valve 13 can be turned in one body, and the collar 16 can be turned by the portion of play L against the parallel valve 13. This construction permits return of the lever 15 automatically from an air-escape position to a fuel-opened position, and consequently prevent the failure to return the lever 15, thus preventing the trouble of an engine beforehand.
摘要翻译：目的：为了防止由于通过相对游隙的一部分将杠杆的开环位置从空气开启/关闭路径的打开位置转到关闭燃料打开状态的关闭位置而不能返回杆的麻烦的套环通过复位弹簧抵靠阀。构成：在一个主体制成的轴环16的底部和杠杆15之间提供扭转复位弹簧25，以及用于沿箭头F的相反方向施加力的平行阀13.轴环16和平行阀13可以被转动在一个主体中，并且套环16可以通过打击部分L的部分转动到平行阀13上。这种结构允许杠杆15自动从空气逸出位置返回到燃料打开位置，并且因此防止未能返回杆15，从而预先防止发动机的故障。

摘要： PURPOSE:To produce side covers of specifications with or without bearings for internal combustion engines at a reduced cost by the use of common dies by attaching and detacthing an annular core to and from the male die of the dies. CONSTITUTION:In a male die 7 of dies 6, a projecting part 10 of an arc shape is formed in the position to be formed with a recess 4 having the same shape on the outside circumference of a boss part 3 for the ball bearing of a side cover 1. If an Al alloy or the like is cast in the cavity 11 in the dies 6 and is molded by die casting, the side cover 1 of the specifications with a bearing 2 is produced. An annular core 9 having an outside diameter equal to the inside diameter of the part 10 is mounted to a projecting part 12 for forming a bearing part in the die 7 to bring the inside circumferential surface of the part 10 and the outside circumferential surface of the core 9 into abutment on each other and to make the run to this part infeasible. If an Al alloy or the like is cast in the cavity 11' of such dies 6' and is molded by die casting, the side cover of the specifications without the bearing is produced.

摘要： PURPOSE:To control the revolving speed of an engine upon sensing the operating state of machinery for works appropriately in the case the machinery is driven by the engine of working machine. CONSTITUTION:The load on an engine J is sensed by a load sensing means C, and compared with the no-load judgement reference value by a load judging means F and with the varying width judgement reference value by a load change judging means G. If both are below the respective reference values, the engine shall be run at a low target revolving speed which was set for no-load operation.

摘要： PURPOSE:To improve the operability of decompressing operation, by accommodating base end sections of a decompressing shaft and a decompressing lever in a recess formed in a valve arm chamber lid so that they may not extend to the operation side of an engine. CONSTITUTION:The valve arm chamber lid 21 mounted on the frontal side of the cylinder head 4 of a horizontal internal combustion engine is formed with the recess 34 at a position that faces an arm section 28a of a suction valve arm 28 of a valve gear accommodated in a valve arm chamber 23 in the valve arm chamber lid 21. A boss section 35 formed at the side of the recess 34 is formed with a shaft insertion hole 36 in parallel with a valve arm shaft 26, and the decompressing shaft 39 is rotatably inserted in the hole 36. The inner end of the shaft 39 is formed with a cam section 40 that faces an engaging projection 41 formed on an arm section 27a of an exhaust valve arm 27, and the decompressing lever 43 is attached to the outer end thereof. When the lever 43 is rotated to the position shown by phantom line, an exhaust valve 31 can be released by the cam section 40 through the exhaust valve arm 27.
