Background technique
At present, the speed regulating mechanism of domestic single cylinder diesel mainly contains two active forces, and the one, the tensile force f 4 that the speed governing extension spring that is spurred by external force produces, another is the centrifugal force F1 that the steel ball speed regulator produces, when having only these two power to reach balance, diesel engine could steady running.
When diesel engine quickens suddenly, promptly by moving speed governing extension spring 9 to the end suddenly under the idling mode, at this moment, F4 is far longer than F1, governor lever is under the effect of F4, the rapid big position of amount that pump rack is pushed to refuel, fuel delivery strengthens suddenly, has substantially exceeded the amount of fuel that declared working condition needs, make fuel oil mix disequilibrium, cause incomplete combustion, the phenomenon of over-emitting black exhaust occurs, influence the smoke intensity and the economic indicator of diesel engine.Equally, under declared working condition, if diesel load increases suddenly, when diesel engine speed descended rapidly, F1 will significantly reduce, and pump rack can move to the direction that strengthens fuel delivery under the effect of F4 equally, the generation of over-emitting black exhaust problem occurs, influence the complete machine service behaviour of diesel engine.
Summary of the invention
When being unexpected acceleration that exists at existing speed regulating mechanism, the purpose of this utility model produces the problem insufficient and that be short of power when increasing of burning because of load because of fuel delivery is excessive, design a kind of fuel delivery that both can limit in rating value, can carry out the single cylinder diesel speed regulating mechanism that has limit stoper and speed governing torsion spring of fuel feeding compensation again automatically.
The technical solution of the utility model is:

Embodiment
Following structure drawings and Examples are further described the utility model.
As shown in Figure 1, 2, 3.
A kind of single cylinder diesel speed regulating mechanism that has limit stoper and speed governing torsion spring, be applicable to all kinds of single cylinder diesels of cylinder diameter between the 95-130 millimeter, comprise speed governing extension spring 9, speed control rod 5, drive link 13, governor lever 1, one end of speed control rod 5 is fixed on the end of drive link 13, the other end of speed control rod 5 links to each other with speed governing extension spring 9, governor lever 1 is installed on the other end of the drive link 13 that drives its rotation and is fulcrum with drive link 13, the galianconism end of governor lever 1 contacts with the steel ball speed regulator, its long arm end links to each other with pump rack, at an end of described speed control rod 5 limit stoper 14 is installed; On an end of drive link 13 installation governor levers 1, a speed governing torsion spring 7 is installed, one end of this speed governing torsion spring 7 is pressed on the galianconism end of governor lever 1, its the other end inserts in the setting sleeve 6 that is fixed on drive link 13 ends (also can directly be connected on the end of drive link 13), as Fig. 1, shown in 2.
It is all same as the prior art that the utility model does not relate to part.
Utilize prior art by suitable improvement, the utility model also can be used in twin-tub or other the similar multi-cylinder diesel engine.
Working procedure of the present utility model is:
Diesel engine is under declared working condition, and by the tensile force f 4 tension speed control rods 5 that speed governing extension spring 9 produces, the moment of torsion that the centrifugal force F1 on the galianconism end that acts on governor lever 1 that the moment of torsion of tensile force f 4 generations this moment and steel ball speed regulator produce produces balances each other, i.e. M
1F4=M
2F1, wherein M
1, M
2Be respectively the length of the arm of force.At this moment, by adjusting stop screw 3 and locking with locking nut 4, stop screw 3 just holds out against on speed control rod 5, F3=0.Meanwhile, speed governing torsion spring 7 is in impaction state and (produces an internal force F2, as shown in Figure 2), speed control rod 5 is dead by limit, diesel engine work is under declared working condition, even wrench governor spring 9 suddenly, the maximum position of speed control rod 5 is defined, its fuel delivery also just is limited on the setting value, and existing speed regulating mechanism does not then have corresponding position-limit mechanism maybe can not reach this requirement.
When diesel load strengthens, the rotating speed of diesel engine descends, at this moment, F1 reduces, governor lever then rotates under the twisting force of speed governing torsion spring 7, the long arm end of governor lever 1 then promotes oil pump gear and moves to the oiling direction, thereby increases fuel delivery automatically, and power is also done corresponding increase when guaranteeing the diesel load increase.Along with the increase of diesel engine speed, F1 also increases thereupon, and the effect of F2 descends thereupon, and till the moment of moment that F1 produces and the tensile force f 4 of speed governing extension spring 9 generations reached new balance, diesel engine is steady running under another operating mode then.
