うにしだものがある。In this type of conventional speed governor, a throttle valve (not shown) is connected to one movable end tub of a governor lever + via a throttle rod, which is rotatably attached to a support shaft j, as shown in Fig. 1.

それだけ負葡加坦時の速度変動幅が低減され易くなる。On the other hand, in engines, especially constant speed conversion engines such as generator-driven engines, the degree of fall in the rotational speed during load operation relative to the rated rotation speed, i.e., the rate of fluctuation (speed I), is kept small (for example, to 5% or less). Moreover, as shown in Fig. 2, this speed fluctuation rate is different when the spring constant of the governor spring g is large and when it is small, and when it is made relatively large, the actual wire number is As shown in , it is known that the speed fluctuation rate θ when load is applied (hereinafter referred to as the speed fluctuation rate under load) becomes larger than the speed fluctuation rate β8 when loaded as shown by the broken line S) when they are reduced. . This is due to the large spring constant, as shown in Figure 3.
Measuring the displacement of the governor spring g when using a governor spring g with a small spring constant, the displacement filL of the governor spring with respect to a change in rotational speed when using a governor spring g with a small spring constant is smaller, that is, the latter is smaller. The greater the change in the opening degree of the throttle valve with respect to the change in rotational speed, the more easily the width of speed fluctuation during negative acceleration is reduced.

lのバネ定数を小さくすることには一定の限界がある。Therefore, in terms of keeping the speed fluctuation rate small,
It is best to set the spring constant of the governor spring band as small as possible, but if the spring constant of the governor spring band is made small, the entire tuning thread will be easier to operate with a small acting force, as shown in Figure 1. As shown in , the speed fluctuation rate at the beginning of load fluctuation, that is, the temporary speed fluctuation rate α, becomes considerably larger than the instantaneous speed fluctuation rate α when the spring constant is made relatively large, and exceeds the permissible fluctuation rate. will occur. Therefore, there is a certain limit to reducing the spring constant of the governor spring l.

るものである。An object of the present invention is to improve the rate of speed fluctuation under load without increasing the rate of nictal fluctuation in an adjustment device that maintains the engine speed within a certain range by balancing the governor weight and governor spring. The displacement force of the thruster, which is displaced in the axial direction according to the tilting angle of the governor weight whose tilting angle changes according to the rotational speed of the engine shaft, and the spring force of the governor spring. An appropriate fuel metering member is connected to one end of a governor lever whose rotational position is determined by balance, and by appropriately rotating the governor lever, the fuel metering member is used to supply fuel to each cylinder of the engine. In a 14-speed system for an internal combustion engine that is capable of controlling a feed rate, an appropriate damper device is provided between a proper position of the governor lever and a proper position of the main body of the 14-speed system so as to operate in the direction of expansion and contraction of the governor spring. It is characterized by several exceptions.

説明を省略する。Hereinafter, the speed governor for an internal combustion engine of the present invention will be explained based on FIG. V. In FIG. This speed governor has the same basic configuration as the conventional speed governor shown in Fig. 1, and the spring constant of the governor spring is shown by the broken line in Fig. 1. The speed fluctuation rate at small loads such as
The difference is that an air set dash board), 2(1) is provided as a damper device for suppressing the sudden displacement of the cabana lever ≠ between ≠h and the side wall /6 of the adjustment device main body. It should be noted that each of the other members is the same as in the case of the conventional example, so the same reference numerals as in the case of the conventional example are given, and detailed explanation thereof will be omitted.

その結果速度変動率が改善されることになる。In this way, if the spring constant of the cabana spring g is reduced, the displacement of the governor lever t in response to engine speed fluctuations becomes larger, and accordingly, the throttle lever io,
In other words, the change in the opening degree of the throttle valve increases, and the engine output is adjusted to more closely match the load fluctuation.
As a result, speed fluctuation rate is improved.

トルバルブの開度が決定されることになる。In addition, in the a11 series system shown in Figure 4, the spring constant of the governor spring g is small, so when there is a fluctuation in engine speed, the governor lever Hiroshi tries to momentarily tilt significantly. In the case of the power lever, the dash board (20) attached to one end of the governor lever acts to suppress the sudden y position of the power lever. in this case,
Dashpot, 201d, simply brakes the sudden movement of the governor lever ≠ when the load fluctuates, but as time passes, the force acting on the governor lever ≠ will be lost. The tilting position i of the governor lever, that is, the opening degree of the throttle valve is determined.
