Technical field
The utility model relates to diesel engine arts, more particularly to a kind of fuel pipe automatic exhauster structure.
Background technique
Single cylinder diesel fuel pipe at present, in the oil supply system course of work, fuel pipe generates gas, and gas cannot
Discharge causes high-pressure oil pump to stop working in time, and user need to unscrew (pipe) bleed screw on high-pressure oil pump, releases gas, and fire
Oil sprays therewith, time-consuming and laborious, inconvenient for operation, influences working efficiency.
Utility model content
The utility model realizes fuel feeding system mainly solving the technical problems that provide a kind of fuel pipe automatic exhauster structure
It is vented automatically in the system course of work, without human intervention, improves working efficiency.
In order to solve the above technical problems, the technical solution that the utility model uses is: provide a kind of fuel pipe from
Dynamic exhaust gear, comprising: fuel tank, filter, high-pressure oil pump, fuel injector, petroleum pipeline, fuel pipe, high-pressure oil pipe, oil return of oil injector
Pipe and automatic exhaust pipe are connected between the fuel tank and filter by petroleum pipeline, are led between the filter and high-pressure oil pump
Fuel pipe connection is crossed, is connected between the high-pressure oil pump and fuel injector by high-pressure oil pipe, between the fuel injector and filter
It is connected by oil return of oil injector pipe, one end of the automatic exhaust pipe and the oil outlet of filter connect, the automatic exhaust pipe
The other end connect with the fuel tank pipe fitting of fuel tank upper end.
In one preferred embodiment of the utility model, fuel pipe generates gas and enters oil by the automatic exhaust pipe
Case is simultaneously discharged in time.
In one preferred embodiment of the utility model, the tank tube weld is on fuel tank.
In one preferred embodiment of the utility model, one end of the automatic exhaust pipe passes through pipe fitting and filter
Oil outlet connection.
The beneficial effects of the utility model are: a kind of fuel pipe automatic exhauster structure that the utility model is pointed out, is realized
It is vented automatically in the oil supply system 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 that fuel pipe generates, automatic-discharging is without human intervention, time saving and energy saving, improves working efficiency.
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 fuel pipe automatic exhauster structure of the utility model.
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.
Referring to Fig. 1, the utility model embodiment includes:
A kind of fuel pipe automatic exhauster structure, comprising: fuel tank 1, filter 2, high-pressure oil pump 3, fuel injector 4, petroleum pipeline
5, fuel pipe 6, high-pressure oil pipe 7, oil return of oil injector pipe 8 and automatic exhaust pipe 9, pass through oil transportation between the fuel tank 1 and filter 2
Pipe 5 connects, and is connected between the filter 2 and high-pressure oil pump 3 by fuel pipe 6, between the high-pressure oil pump 3 and fuel injector 4
It is connected, is connected between the fuel injector 4 and filter 2 by oil return of oil injector pipe 8, the automatic exhaust by high-pressure oil pipe 7
One end of pipe 9 is connect with the oil outlet of filter 2, the other end of the automatic exhaust pipe 9 and the fuel tank pipe fitting of 1 upper end of fuel tank
Connection.
Working principle: when it is implemented, in working process of diesel engine, fuel from fuel tank 1 enters filter by petroleum pipeline 5
2, after the clean fuel oil through filter enter high-pressure oil pump 3, then after high pressure fuel combustion system sprayed by high-pressure oil pipe 7, from
And Fuel injection system is completed, while part fuel oil enters filter 2 by oil return of oil injector pipe 8, automatic 9 one end of exhaust pipe passes through pipe
Connector is connect with 2 oil outlet of filter, and the other end of automatic exhaust pipe 9 is connect with the fuel tank pipe fitting of 1 upper end of fuel tank, diesel engine
In the course of work, fuel pipe generates gas, enters fuel tank 1 by automatic exhaust pipe 9 and is discharged in time, guarantees high-pressure oil pump 3
It works normally.
In conclusion a kind of fuel pipe automatic exhauster structure that the utility model is pointed out, realizes that oil supply system is worked
It is vented automatically 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, fuel oil
The gas that pipeline generates, automatic-discharging is without human intervention, time saving and energy saving, improves working efficiency.
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
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
