Background technique
In the high-pressure oil pump course of work, the gas generated in fuel pipe gathers high-pressure oil pump, and gas cannot be arranged in time
High-pressure oil pump is caused to stop working out, user need to unscrew bleed screw, release gas, and fuel oil sprays therewith, waste diesel oil, take
When it is laborious, it is inconvenient.Meanwhile gas causes pipe breakage and interface oil leak in the presence of easily causing fuel pipe pressure big.
Summary of the invention
The utility model realizes high pressure oil mainly solving the technical problems that provide a kind of high-pressure oil pump automatic deflation mechanism
Automatic deflation during pump work.
In order to solve the above technical problems, the technical solution that the utility model uses is: provide a kind of high-pressure oil pump from
Dynamic air-release mechanism, comprising: fuel tank, petroleum pipeline, filter, fuel pipe, high-pressure oil pump, high-pressure oil pipe, fuel injector, oil return of oil injector
Pipe, bleeder pipe and pipe connecting bolt with holes are connected between the fuel tank and filter by petroleum pipeline, the filter and high pressure oil
It is connected between pump by fuel pipe, is connected between the high-pressure oil pipe and fuel injector by high-pressure oil pipe, the fuel injector and filter
It is connected between clear device by oil return of oil injector pipe, pipe fitting is provided on the fuel tank, offers outlet on the high-pressure oil pump
Mouthful, described bleeder pipe one end is connect with pipe fitting, and the bleeder pipe other end is connect by pipe connecting bolt with holes with gas outlet.
In one preferred embodiment of the utility model, oilhole is provided in the pipe connecting bolt with holes.
In one preferred embodiment of the utility model, the pipe fitting is welded on fuel tank.
In one preferred embodiment of the utility model, the gas that the high-pressure oil pump generates enters fuel tank by bleeder pipe
And it is discharged in time.
The beneficial effects of the utility model are: a kind of high-pressure oil pump automatic deflation mechanism that the utility model is pointed out, is realized
Automatic deflation in the high-pressure oil pump course of work avoids gas that from cannot being discharged in time and influence high-pressure oil pump working performance；Diesel engine
In the course of work, the gas of high-pressure oil pump aggregation, automatic-discharging is without human intervention, time saving and energy saving, improves working efficiency, subtracts
Few pipe breakage and interface oil leak.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model
Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings, in which:
Fig. 1 is a kind of structural schematic diagram of one preferred embodiment of high-pressure oil pump automatic deflation of the utility model mechanism；
Fig. 2 is the structural schematic diagram of pipe connecting bolt with holes.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
The utility model embodiment includes: referring to FIG. 1-2,
A kind of high-pressure oil pump automatic deflation mechanism, comprising: fuel tank 1, petroleum pipeline 2, filter 3, fuel pipe 4, high-pressure oil pump
5, high-pressure oil pipe 6, fuel injector 7, oil return of oil injector pipe 8, bleeder pipe 9 and pipe connecting bolt 10 with holes, the fuel tank 1 and filter 3
Between connected by petroleum pipeline 2, connected between the filter 3 and high-pressure oil pump 5 by fuel pipe 4,6 He of high-pressure oil pipe
It is connected, is connected between the fuel injector 7 and filter 3 by oil return of oil injector pipe 8, institute by high-pressure oil pipe 6 between fuel injector 7
It states and is provided with pipe fitting 11 on fuel tank 1, gas outlet, described 9 one end of bleeder pipe and pipe fitting 11 are offered on the high-pressure oil pump 5
Connection, 9 other end of bleeder pipe are connect by pipe connecting bolt 10 with holes with gas outlet, setting in the pipe connecting bolt 10 with holes
There is oilhole 12.
Working principle: when it is implemented, in working process of diesel engine, fuel from fuel tank 1 enters filter by petroleum pipeline 2
3, after the clean fuel oil through filter enter high-pressure oil pump 5, then after high pressure fuel fuel injector 7 entered by high-pressure oil pipe 6 spray into
Combustion system, to complete Fuel injection system, while part fuel oil enters filter 3, bleeder pipe 9 one by oil return of oil injector pipe 8
End is connect with pipe fitting 11, and 9 other end of bleeder pipe is connect by pipe connecting bolt 10 with holes with gas outlet, will be entered in the course of work
The gas of high-pressure oil pump 5 enters fuel tank by bleeder pipe 9 and is discharged in time.
In conclusion a kind of high-pressure oil pump automatic deflation mechanism that the utility model is pointed out, realizes that high-pressure oil pump is worked
Automatic deflation in journey avoids gas that from cannot being discharged in time and influence high-pressure oil pump working performance；In working process of diesel engine, high pressure
The gas of oil pump aggregation, automatic-discharging is without human intervention, time saving and energy saving, improves working efficiency, reduces pipe breakage and interface
Oil leak.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
