The axle shaft gear connection of fluid servomotor bottom.
Further, the counterbalance spring, buffer and compensating piston are located on the same axis of enclosure.
Further, the fluid servomotor is located at buffer right-hand member, and the lower end of fluid servomotor is truncated cone-shaped structure.
Further, the buffer inside is for T-shaped structure and can be moved in compensating piston.
Further, the counterbalance spring is welded with rocking bar, and counterbalance spring inside is connected with compensating piston by nut.
Compared with prior art, the beneficial effects of the invention are as follows：A kind of this kind of compensation of diesel engine high accuracy speed regulator
Spring, buffer and compensating piston are located on the same axis of enclosure, and sensitivity is higher when decelerator is worked；Hydraulic pressure
Servomechanism is located at buffer right-hand member, and the lower end of fluid servomotor is truncated cone-shaped structure, makes the use material of speed regulator
Material is saved and the gap between inside is smaller；Counterbalance spring is welded with rocking bar and counterbalance spring inside passes through spiral shell with compensating piston
Mother's connection, allows speed regulator that the scope of rotating speed, and a kind of this kind of diesel engine high accuracy rotating speed are adjusted according to user
Adjusting apparatus are easy to use, and degree of regulation and sensitivity are high, good stability, and wide adaptation range is practical, are adapted to promote
Use.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly and completely
Description, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments, based on this
Embodiment in invention, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, the scope of protection of the invention is belonged to.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of diesel engine high accuracy speed regulator, including it is outer
Shell 13 and the fly weight 3 being arranged on inside shell 13；The fly weight 3 is fixedly connected by fly weight support 2 with speed bar 1
And speed bar 1 is located at the pivot of fly weight 3；The speed bar 1 be connected with rocking bar 5 by hinge and the one end of rocking bar 5 with set
The compensating piston 8 inside fluid servomotor 7 is put to be fixedly connected；Buffer is installed between the compensating piston 8 and rocking bar 5
6 and inside connected with Throttle needle valve 9 by pipeline；The Throttle needle valve 9 be arranged on the top of drive shaft 11 and and gear
Oil pump 10 is connected；The one end of the compensating piston 8 is closely connected with the counterbalance spring 4 being fixed on shell 1；The shell
13 inside set connecting rod 12 and positioned at the one end of speed bar 1；The connecting rod 12 be arranged on the bottom of fluid servomotor 7
The gear of drive shaft 11 connection；A kind of counterbalance spring 4 of diesel engine high accuracy speed regulator, the and of buffer 6
Compensating piston 8 is located on the same axis inside shell 13, and sensitivity is higher when decelerator is worked；Fluid servomotor 7
Positioned at the right-hand member of buffer 6, and the lower end of fluid servomotor 7 is truncated cone-shaped structure, makes the use material of speed regulator
Save and the gap between inside is smaller；Counterbalance spring 4 is welded and the inside of counterbalance spring 4 and compensating piston 8 with rocking bar 5
Connected by nut.
As concrete principle of the invention：The speed regulator internally increases an elastic link, it by buffer 6,
Compensating piston 8, counterbalance spring 9, the composition elastic link of Throttle needle valve 10, working oil is filled with the oil cylinder of buffer 6, left
Right two spaces are connected by pipeline with Throttle needle valve 10, when being moved left and right after the stress of buffer 6, liquid in the cylinder of buffer 6
Another space is flowed to through Throttle needle valve 10 from a space, because the throttling of Throttle needle valve 10 makes the mobile than slow of compensating piston 8
The movement for rushing device 6 is delayed, plays cushioning effect, due to the function of the flexible recovery of counterbalance spring 9 of being compressed, makes A points
Drive compensating piston 6 to be moved right in buffer oil cylinder, return to origin-location, the oily warp knuckle in the oil cylinder of compensating piston right
Stream needle-valve 8 is back to left, and last counterbalance spring 9 and rocking bar 5 return to origin-location, have also returned to speed bar 1
Beginning position, the engine speed after such speed regulation process terminates can keep former speed constant, play speed governing cushioning effect.
