Abstract
The utility model relates to an electronic oil nozzle and mainly solves the problems of high possibility of oil leakage and difficulty for guaranteeing the coaxiality when the conventional electronic oil nozzle is used. An oil outlet pipe is sleeved on the outer rings of a valve needle and an armature; and the oil outlet pipe and an oil inlet pipe are coaxially sleeved or coaxially integrated. The electronic oil nozzle has the characteristics of good sealing performance and high coaxiality.
Description
Technical field
The utility model relates to a kind of engine fuel injector field, refers in particular to a kind of electronic oil-jet.
Background technique
Oil sprayer itself is a normally close valve, is moved up and down the switching of control valve by needle.When ECU assigned the oil spout instruction, its voltage signal can make flow through coil in oil sprayer of electric current, produces magnetic field valve rod is picked up, and allows valve opening that oil plant can be sprayed from nozzle opening.The great advantage of spraying fuel feeding is exactly that the control of fuel delivery is very accurate, allows engine under any state, correct air fuel ratio can be arranged, and not only allows engine keep running smooth and easy, and its waste gas also can conform with the standard of environmental regulation.
As the oil sprayer of one of critical component of electronic fuel injection engine, the valve rod in oil sprayer, needle and body seal are bad, will cause the poor and leakage of oil of the anti-sealing of oil sprayer, will directly affect the performance of motor.Existing oil sprayer is easy to process, and oil inlet pipe, armature and oil outlet tube are split type manufacturing, after then being welded in one successively, is fitted into needle-valve.Connect because each end face adopts welding manner, often exist weld easily to reveal, and the coaxality of each parts problem that is difficult to guarantee.
The model utility content
In order to overcome deficiency and the defective in background technique, the utility model provides a kind of electronic oil-jet, mainly solves the problem that existing electronic oil-jet exists easy oil leakage and coaxality to be difficult to guarantee in use.
the technical solution of the utility model is: a kind of electronic oil-jet, comprise shell, and suit oil inlet pipe in the enclosure, valve rod and needle, described valve stem casing is contained in oil inlet pipe, and the place, axle center is provided with the first through hole, the place, axle center of described needle is provided with second through hole corresponding with described the first through hole, be connected by elastic component between described valve rod and needle, described valve rod outer ring sleeve is provided with armature, the upper-end surface phase Spielpassung of one end of described armature and described needle, it is characterized in that: described needle and armature outer ring sleeve are equipped with oil outlet tube, described oil outlet tube is connected with the coaxial socket of oil inlet pipe or coaxial one.
Be provided with the bounding means that fits with described elastic component one end in described valve rod.
One end of described oil inlet pipe is nested in oil outlet tube, and welds mutually with oil outlet tube.
Described bounding means is filter screen.
Described elastic component is spring.
The beneficial effects of the utility model: owing to taking such scheme, electronic oil-jet of the present utility model, be located at oil outlet tube in armature, oil outlet tube and oil inlet pipe setting that coaxial socket or coaxial one connect, effectively solve the shortcoming of the poor and easy oil leakage of each element coaxial degree in needle-valve, had good seal performance, characteristics that coaxality is high.
Description of drawings
Fig. 1 is the utility model embodiment one structure sectional view.
Fig. 2 is the utility model embodiment two structure sectional view.
In figure, shell 1, oil inlet pipe 2, valve rod 3, the first through holes 31, armature 4, elastic component 5, needle 6, the second through holes 61, oil outlet tube 7, bounding means 8.
Embodiment
The below is described further embodiment one of the present utility model for accompanying drawing:
by shown in Figure 1, this electronic oil-jet, comprise shell 1, and be sleeved on oil inlet pipe 2 in shell 1, valve rod 3 and needle 6, described valve rod 3 is sleeved in oil inlet pipe 2, and the place, axle center is provided with the first through hole 31, the place, axle center of described needle 6 is provided with second through hole 61 corresponding with described the first through hole 31, be connected by elastic component 5 between described valve rod 3 and needle 6, described valve rod 3 outer ring sleeves are provided with armature 4, the upper-end surface phase Spielpassung of one end of described armature 4 and described needle 6, described needle 6 is equipped with oil outlet tube 7 with armature 4 outer ring sleeves, described oil outlet tube 7 is connected with the coaxial socket of oil inlet pipe 2 or coaxial one.The oily device of disputing is normally close valve, and high pressure oil is entered in the needle-valve cavity volume by the place, axle center of oil inlet pipe 2, and do not open for oil sprayer this moment, and high pressure oil is stored in holding cavity.When ECU assigned the oil spout instruction, its voltage signal can make flow through coil in oil sprayer of electric current, produces magnetic field needle is picked up, and allows valve opening that oil plant can be sprayed from nozzle opening, formed vaporificly, was convenient to abundant burning.Be provided with the gap of 6-8mm between armature and needle, when magnetic field picked up valve rod, armature had the restriction of FROM to needle, prevented from that electric current is excessive to cause oil spout excessive.Be located at oil outlet tube in armature, and the integral type setting of oil inlet pipe and oil outlet tube, avoided the welding of oil inlet pipe and oil outlet tube joining place, effectively solved interior each element coaxial degree of needle-valve poor, the shortcoming that soldering point is easily revealed has good seal performance, characteristics that coaxality is high.
Be provided with the bounding means 8 that fits with described elastic component 5 one ends in described valve rod 3.After the axial limiting of bounding means to elastic component one end that arranges in described needle, the range of movement of needle is controlled in the elastic strain of the relative needle of the other end, has reached the effect of controlling more accurately flow.
As preferably, described bounding means 8 is set to filter screen, to the axial limiting of elastic component 5 one ends, is controlled accurately the oil spout precision, and has the effect of oil strain, prevents from stopping up needle-valve, causes oil pressure excessive, causes leakage.
As preferably, described elastic component 5 is spring, has saved manufacture cost.
Embodiment two relative embodiments' one difference is:
By shown in Figure 2, an end of described oil inlet pipe 2 is nested in oil outlet tube, and welds mutually with oil outlet tube 7.Be located at oil outlet tube in armature, oil outlet tube arranges with the split type nested mode of oil inlet pipe, has removed two spot welding between oil outlet tube, oil inlet pipe and armature, adopts the two direct welding manners of pipe, and turnover has easily manufactured, and secrecy is good, the effect that coaxality is high.
Embodiment should not be considered as the restriction to model utility, but any improvement of doing based on spirit of the present utility model, all should be within protection domain of the present utility model.
