バナ装置としての応答性が悪くなり、エンジン回
転数の制御精度が低下するという問題があつた。<<Problem to be solved>> However, in the above-mentioned conventional device, the operating lever 43
Since the rotation shaft 46 of the engine is pivoted to a pivot hole 48 provided in a fixed wall 47 of the engine via an oil seal 49, the operating lever 4 is moved by the frictional force of the oil seal 49.
In addition, this frictional force causes hysteresis to remain during operation, resulting in poor responsiveness as a governor device and a reduction in accuracy in controlling engine speed.
加えて、ポンプ室４０が大気よりも圧力が高く
なつていることから、ポンプ室４０の潤滑油が枢
支孔４８から外部に漏出して周囲を汚損するとい
う問題があつた。 In addition, since the pressure in the pump chamber 40 is higher than that of the atmosphere, there is a problem in that the lubricating oil in the pump chamber 40 leaks out from the pivot hole 48 and contaminates the surrounding area.

In addition, since the pump housing and the mounting base and between the mounting base and the solenoid are sealed with sealing means, even if lubricating oil leaks into the space inside the mounting base,
The lubricating oil will no longer leak out of the machine.

It communicates with port 16,
The fuel injection camshaft 10 operates a fuel injection pump 17 to forcefully feed fuel to a fuel injection nozzle 19 of a sub-combustion chamber 18 communicating with the combustion chamber 15.

調節操作して行なわれる。 Then, the amount of fuel injected from the fuel injection nozzle 19 is controlled by the electronic control device 20 using the solenoid 2.
This is done by controlling the pump 1 and adjusting the rack 22 of the fuel injection pump 17.
このソレノイド２１は、第２図に示すように、
燃料噴射ポンプを取付けたポンプハウジング２３

にしてある。 In this way, the operating shaft 2 of the solenoid 21 is attached to the pump housing 23 via the mounting base 24.
5 passes through an insertion hole 26 formed in the pump housing 23, and its tip is inserted into the pump housing 23.
It enters into the fuel injection pump 17 and comes into direct contact with the end face of the rack 22 of the fuel injection pump 17, and the rack 22 is operated to the fuel reduction side A by operating the solenoid 21 toward the advance side. In addition, on the end surface of the rack 22 opposite to the end surface that the operating shaft 25 is in contact with,
A push rod 28 is in contact with the pump housing 23, and a return spring 27 disposed between the push rod 28 and the pump housing 23 forces the rack 22 toward the fuel increasing side B.

してある。 A sealing means 31 consisting of an O-ring is provided between the cylindrical mounting base 24 of the solenoid 21 and each mounting surface S of the pump housing 23 and the solenoid 21, and this sealing means 31 prevents fuel injection within the pump housing 23. The lubricating oil used to lubricate the camshaft 10 is prevented from leaking out through the insertion hole 26 of the operating shaft 25 through the cylindrical hole space 32 of the cylindrical mounting base 24.

侵入するのを防止するようになつている。 Further, the operating shaft 25 of the solenoid 21 is provided with a rubber boot 35 that is extendable and retractable from the center thereof to the solenoid body.
This prevents the lubricating oil that has lubricated the fuel injection camshaft 10 from entering the inside of the solenoid 21 through the insertion hole 26 of the operating shaft 25.
尚、上記ゴムブーツ３５に代えて、第３図に示
