Abstract
The utility model discloses an edge filter for an oil atomizer, which comprises an oil atomizer body. An oil flow channel is arranged in the oil atomizer body; an oil inlet is arranged at one end of the oil flow channel; an oil outlet is arranged at the other end of the oil flow channel; a filter core is installed in the oil flow channel; an oil inlet longitudinal groove is arranged on the cylindrical surface of the filter core on one side close to the oil inlet; an oil outlet longitudinal groove is arranged on the cylindrical surface of the filter core on one side close to the oil outlet of the oil atomizer; the oil inlet longitudinal groove and the oil outlet longitudinal groove are arranged in a staggering way; and the filter core is in clearance fit with the cavity of the oil atomizer body. By adopting the clearance between the filter core and the cavity of the oil atomizer body, micro impurity is left in the oil groove, therefore, the purpose of filtering is achieved, and the service life of the oil atomizer is prolonged.
Description
Technical field
The utility model relates to a kind of preceding device that fuel oil is filtered of diesel injector that enters.
Background technique
In order to guarantee that diesel engine works incessantly, the fuel oil that comes out from fuel tank is removal of contamination carefully.If fuel cleaning is bad, then the precision pair in Injection Pump and the oil sprayer can wear and tear or block soon.The wearing and tearing of precision pair will cause that each oil supply cylinder is inhomogeneous, and fuel consumption increases and power descends.Two filter cleaners generally all are installed in diesel engine.First is a strainer, and it is installed in before the transfer pump, leaches bigger impurity.Second is fine cleaner, can leach small impurity, and it is installed in before the Injection Pump.Fuel oil also is equipped with high pressure chink type filter cleaner on a lot of diesel engines before entering oil nozzle, do to filter for the last time.
Generally use the chink type filter cleaner in the industry at present, but because structural design is unreasonable and cause the fuel oil throttling owing to blocking in the filtering process, fuel feeding deficiency in asking during the unit of causing causes diesel engine power deficiency and over-emitting black exhaust phenomenon.
The model utility content
Technical problem to be solved in the utility model provide a kind of can the filtering fuel oil in the oil sprayer chink type filter cleaner of impurity.
For solving the problems of the technologies described above, the technical solution of the utility model is: oil sprayer chink type filter cleaner, comprise oil injector body, be provided with oil flow channel in the described oil injector body, one end of described oil flow channel is a filler opening, the other end of described oil flow channel is an oil outlet, in the described oil flow channel filter core is installed, described filter core is provided with the vertical oil groove of oil-feed near the cylinder of described filler opening one side, described filter core is provided with fuel-displaced vertical oil groove near the cylinder of described oil sprayer oil outlet one side, the vertical oil groove of described oil-feed and described fuel-displaced vertical oil groove mutual dislocation, the inner chamber Spielpassung of described filter core and described oil injector body.
As a kind of technical improvement, the cross section of described fuel-displaced vertical oil groove is a crossing spline.
Owing to adopted technique scheme, oil sprayer chink type filter cleaner, comprise oil injector body, be provided with oil flow channel in the described oil injector body, one end of described oil flow channel is a filler opening, the other end of described oil flow channel is an oil outlet, in the described oil flow channel filter core is installed, described filter core is provided with the vertical oil groove of oil-feed near the cylinder of described filler opening one side, described filter core is provided with fuel-displaced vertical oil groove near the cylinder of described oil sprayer oil outlet one side, the vertical oil groove of described oil-feed and described fuel-displaced vertical oil groove mutual dislocation, the inner chamber Spielpassung of described filter core and described oil injector body.By the gap of filter core and oil injector body inner chamber, some small impurity are stayed in the oil groove, reach the purpose of filtration, and can prolong the working life of oil sprayer.

Embodiment
Below in conjunction with embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, oil sprayer chink type filter cleaner, comprise oil injector body 5, be provided with oil flow channel 6 in the described oil injector body 5, one end of described oil flow channel 6 is a filler opening 7, the other end of described oil flow channel 6 is an oil outlet 1, in the described oil flow channel 6 filter core 2 is installed, described filter core 2 is provided with the vertical oil groove 4 of oil-feed near the cylinder of described filler opening 7 one sides, described filter core 2 is provided with fuel-displaced vertical oil groove 3 near the cylinder of described oil sprayer oil outlet 1 one sides, the vertical oil groove 4 of described oil-feed and described fuel-displaced vertical oil groove 3 mutual dislocation, the inner chamber Spielpassung of described filter core 2 and described oil injector body 5.
The cross section of described fuel-displaced vertical oil groove 3 is a crossing spline.
During work, the high pressure oil of coming from high-pressure oil pipe is by described filler opening 7, enter the vertical oil groove 4 of described oil-feed, high pressure oil enters into described fuel-displaced vertical oil groove 3 by the gap of described filter core 2 with described oil injector body 5 inner chambers, at last by described oil outlet 1 ejection.
By the gap of filter core and oil injector body inner chamber, some small impurity are stayed in the groove, reach the purpose of filtration, and can prolong the working life of oil sprayer.After the oil outlet end cross section is improved to the cruciate flower groove, no matter how, no longer there is the diesel engine performance deterioration problem that causes because of fuel oil throttling problem in the processing of oil injector body oil duct bottom.
