It is possible to eliminate play between the lever member and the connecting member that make up the link mechanism and between the connecting member and the rack pin, improving governor performance, and making it possible to operate only the rack pin by separating it from the link mechanism. This made it possible to stop the diesel engine.

As is well known, a governor device, which is a speed control device for a diesel engine, is installed in the fuel injection pump to keep the rotation speed of the diesel engine constant, prevent overspeed, and prevent the engine from stopping during overload operation. It's on. Figure 1 shows its general structure, where 1 is a fuel injection pump driven by the rotation of a camshaft 2 connected to the crankshaft of a diesel engine, and 3 is a plunger etc. to adjust the amount of fuel injection. This is a rack pin protruding from the side wall of the pump body for rotating the pump. This rack pin 3
is movable within a certain range in the horizontal direction,
In the illustrated example, it is located at the fuel injection amount upper limit position.
One end of a connecting member 4 is pivotally supported on this rack pin 3, and the other end of the connecting member 4 is pivotally supported on an action point portion 5a of a lever member 5. A spring 6 is hooked to the power point side of the lever member 5 for biasing the rack pin 3 in the direction A to increase the fuel injection amount, and a centrifugal weight (not shown) connected to the camshaft 2 is used to control the diesel engine. A force (governor force) F proportional to the rotational speed is applied to the force point portion 5 of the lever member 5.
b to balance the spring force 6 mentioned above. Therefore, when the rotational speed of the diesel engine increases and the governor force F overcomes the spring force, the rack pin 3 is pushed and moved via the lever member 5 and the connecting member 4 to reduce the fuel injection amount.

点があつた。 However, in the case of conventional governor devices,
Since it was a simple link mechanism, there were no gaps between the lever member 5 and the connecting member 4, and between the connecting member 4 and the rack pin 3.
There is play or backlash between the lever member 5 and the rack pin 3, which reduces the responsiveness between the lever member 5 and the rack pin 3, resulting in a decrease in governor performance. Also, the rack pin 3 is connected to the connecting member 4 and the lever member 5.
Since the rack pin 3 is restrained by the spring 6 via the spring 6, in order to directly move the rack pin 3 in the direction B that decreases the fuel injection amount, a large force is required to resist the spring force. Direction B
It was difficult to stop the diesel engine. For this reason, conventionally the engine was stopped by forcibly opening the intake valve or exhaust valve with a decompression lever, but with this method, the fuel injection pump works to supply fuel until the engine completely stops. Therefore, it had the disadvantage of causing fuel loss.

る。 In order to achieve the above object, the present invention has a rack pin that increases or decreases the injection amount of the fuel injection pump.
A connecting member whose other end is pivotally supported via a pivot shaft at the point of action of the lever member that transmits the governor force; a sliding hole with a matching long hole; a tension spring that is stretched around the pin and the pivot shaft and presses the pin to the upper limit position side end of the hole; This configuration constitutes a governor device for a diesel engine, which is equipped with an operation lever for moving.

ねにより各枢支部のガタが防止される。 The governor force is transmitted to the rack pin via the lever member and the connecting member, but since a tension spring is stretched between the rack pin and the pivot shaft and the rack pin is pressed against the upper limit position side end of the slide hole, the governor force is transmitted to the rack pin via the lever member and the connecting member. is effectively transmitted to the rack pin, improving governor performance. Moreover, the tension spring prevents rattling of each pivot part.

製造が容易で、コストがかからない。 In particular, only the rack pin can be easily moved to the lower limit position of the slide hole using the operating lever against the spring force, making it possible to easily stop the diesel engine. In addition, the structure is simple, just by forming a long slide hole in the connecting member and passing a tension spring between the rack pin and the pivot shaft.
Easy to manufacture and low cost.

イヤを介して遠隔操作されるようになつている。 In FIG. 2, in which the same reference parts are given to the same parts as those described above, 7 is a pivot shaft for pivoting one end of the connecting member 4 to the action point 5a of the lever member 5, and the lever member It is fixed on the 5th side.
An elongated slide hole 8 is formed at the other end of the connecting member 4 so that the rack pin 3 can be moved from its fuel injection amount upper limit position U to its lower limit position R in its non-operating position. A rack pin 3 is slidably engaged therein. A tension spring 9 is stretched between the rack pin 3 and the pivot shaft 7. The spring force of this tension spring 9 is much smaller than that of the biasing spring 6 of the lever member 5, and is set larger than the sliding resistance of the rack pin 3, so that only the rack pin 3 is moved into the slide hole 8 with a minute force. The rack pin 3 can be moved in the direction of decreasing the fuel injection amount along the direction A, and the rack pin 3 can be returned naturally to the direction A of increasing the fuel injection amount. On the other hand, a rack pin operating lever 1 is provided near the rack pin 3 of the fuel injection pump 1 for engaging the rack pin 3 and moving it in the direction of decreasing the fuel injection amount as shown in FIG.
0 is pivotally supported via a shaft 11. The rack pin operating lever 10 is adapted to be remotely operated via a link or wire (not shown).

り、ガバナー性能の向上が図れる。 According to the above configuration, the rack pin 3 and the pivot shaft 7
and are restrained by the spring force of the tension spring 9,
Even if there is a gap between each pivot, it is possible to prevent rattling. Since the rack pin 3 is biased and engaged by the tension spring 9 with the end of the slide hole 8 of the connecting member 4 on the side of the lever member 5, the lever force F can be transmitted effectively. This improves the responsiveness between the lever member 5 and the rack pin 3, and improves the governor performance.
また、ラツクピン3はスライド孔8の範囲内で

め、燃料の損失を防止することができる。 Furthermore, since the rack pin 3 is freely movable within the range of the slide hole 8, only the rack pin 3 can be moved in the fuel injection amount decreasing direction B without moving the lever member 5, and the force at this time is the tension spring. 9
Since the force required to overcome the spring force is sufficient, operation using the rack pin operating lever 10 is extremely easy. Therefore, the diesel engine can be stopped by operating the rack pin 3. In this case, the diesel engine is stopped by reducing or stopping the fuel on the fuel injection pump 1 side, thereby preventing fuel loss.
