Realize to the gauge of fluid space 37 side 36 towards fluid space 37 of overdamp element 32.
When armature 4 is moved along closing direction 30, fluid is expelled from fluid space 37, it is achieved thereby that hydraulic pressure hinders
Buddhist nun.The energy that damping element 32 is stored when moving in spring element 34 becomes freely again when opening next time.
In this embodiment, the pressure medium being arranged in fluid space 37 is related to be injected in space 16 by valve 1
Fluid.In the principle also, it is contemplated that inner space 6 and the correspondingly depressed part 33 with independent liquid medium in other words
Pressure medium is filled, for example to spray into fuel gas or other gaseous fluid.
In this embodiment, the fluid space 37 in depressed part 33 is only connected via gap 35 with inner space 6.Additionally,
In this embodiment, the damping element 32 is directly manipulated by armature 4.It is also contemplated that for example, by middle ring in principle
Indirect operation.Additionally, depressed part 33 can be not only provided on housing component 7, but it is also disposed on other components 7, this other
Component 7 is integrated into valve chest 8 and place is fixedly placed in valve chest 8.Depressed part 33 is designed and is being designed as housing
It is a preferred embodiment in the component 7 of part 7.
Housing component 7 has a side 40, and the side 40 is towards the side 41 of armature 4.The cloth in the case of side 40,41
It is set to parallel to each other.The geometry of valve 1 (especially valve chest 8) is set in this wise in the case so that these sides 40,
(i.e. always) is spaced apart from each other under the possible attitude of 41 in operation each.Thus, minimum spacing is set in this wise, makes
The enough fluid communications between fluid space 37 and inner space 6 must be ensure that by gap 35.In addition by valve (especially shell
Body part 7) geometry ensure that one or more media of armature 4 are through-flow, and 42 highests of drilling are covered by such degree, are made
Can be realized in each possible operation attitude it is also enough through-flow, to make fuel drill 42 from one via medium is through-flow
Region 43 is transported to the seal receptacle on valve closed shape 13.
In the design, can be adjusted in closing course by the gap 35 between damping element 32 and depressed part 33
The optimal damping action of section setting.This can for example be realized by selecting the diameter of spherical damping element 32.Spring element 34
Can design in this wise so that the spring element 34 only lightly presses damping element 32 towards the direction of armature 4.Thus may be used
Constantly or at least to produce the contact between damping element 32 and armature 4 in a part for moving region 22.Any
In the case of, contact is all produced on the end of moving region 22 when armature 4 is adjusted along closing direction 30.
Fig. 2 is idealizing the functional flow diagram that view shows the possibility design for explaining valve 1.In this situation
Under, on right side, part is outlined with amplify that details shows left curve map.The time is labeled as on the horizontal scale, and in vertical seat
Put on and different stroke z or corresponding stroke change curves are shown.These stroke change curves can for example be based on modeling
To calculate and for harmonious (Abstimmung) of valve 1 (especially damping unit 31).Shown stroke change curve
Drawn in the case of no damping unit 31 in the case.In manipulation process, armature 4 is first against the quilt of closing direction 30
Manipulate, and adjusted along closing direction 30 by means of needle 10 by pin closing spring 24 after a certain time period, so that
Draw the stroke change curve 44 of armature 4.By armature 4 after operation is by armature free path 19, needle 10 is opened, and
Closed along closing direction 30 by pin closing spring 24 after certain retention time, it follows that be connected with needle 10
The stroke change curve 45 of valve closed shape 13.In addition show that valve seat 12 is (or imaginary on valve seat 12 on seal receptacle
Line) stroke change curve 46.The difference of the stroke change curve 45 of valve closed shape 13 and the stroke change curve 46 of valve seat 12
Value 47 is equally illustrated.Reference line 48 is shown in addition.If difference 47 exceedes reference line 48, this means seal receptacle is to open
And fuel be injected into via spray-hole 15.Further it is shown that the stroke change curve 49 of backstop 18, the backstop 18 is in electricity
Consumingly sprung into respectively in region 50,51 when pivot 4 is along 30 backstop of closing direction, this is caused due to the flexibility of needle 10.
The low rigidity of shown valve actuation mechanics combination needle 10 high result in pin resilience in fig. 2.In the case,
When the backstop of valve closed shape 13 is on valve seat 12, the deformation on seal receptacle is occurred in that, as shown in stroke change curve 46
Like that.Correspondingly occur in that with reference to such as the stroke by the valve closed shape 13 shown by stroke change curve 45 and with reference to as led to
The stroke of the backstop 18 shown by overtravel change curve 49.This all situations is all after valve closed shape 13 is punched into valve seat
Soon realized in time point t1 on valve seat 12.Between time point t1 and t2, the stretching, extension phase with valve seat on valve seat 12
Than clearly more powerfully relatively soft needle 10 compresses.The energy stored when springing into is exported again in ensuing ejection, by
This needle rebounds.Thus, valve closed shape 13 is not contacted with valve seat 12 between time point t2 and t3 and does not thus apply sealing
Effect.The region 52 of difference 47 shows this point, because difference 47 is located on reference line 48 in this place.Thus in time point t2 and
Occur in that the undesirable of fuel sprays into (Nacheinspritzung) again between t3, this causes having for raising in internal combustion engine
Evil material discharge.
By damping unit 31, armature 4 is set to be damped in its motion carried out along closing direction 30.Thus, especially
For the change curve shown in Fig. 2, backstop of the armature 4 in backstop 18 is damped.It means that backstop 18
Stroke change curve 49 is ad hoc decayed in region 50,51.In the case, when armature 4 is moved along closing direction,
The damping of armature 4 preferably just had been carried out before the armature 4 first time backstop is in backstop 18.Thus there is decay in result,
The decay especially causes the performance being damped in region 50,51.
Thus, less energy is stored when needle 10 springs into, so as to can accordingly less again in next ejection
It is output.Thereby reduce the resilience of needle 10.Sealing function in improvement mode thus, it is possible to be applied.It is possible thereby to ad hoc
Difference 47 is set to decay in region 52.
Fig. 3 shows the Local map for being represented with III in Fig. 1 of the valve according to second embodiment.Set in this embodiment
Be equipped with throttling drilling and/or filling drilling 53, throttling drilling and/or filling drilling 53 make the fluid space 47 of depressed part 33 with
Fluid space 14 in the inner space 6 of valve chest 8 is connected.Thus throttling action especially can additionally be had influence on.Depending on valve 1
Depending on design, throttling drilling and/or filling drilling 53 can also realize depressed part 33 with the through-flow of fluid.Such as due to medium
Thus deposition that is aging and constituting is avoided.This deposition may in the case of the fuel for example due to high temperature under resinification
(Verharzen) occur.
In addition figure 3 illustrates another measure, the measure can drill and/or filling drilling 53 with throttling in principle
Independently realize.The measure is boundary element 54, and the gauge of boundary element 54 damping element 32 is against closing direction 30
Motion path.Boundary element 54 especially can be constructed circlewise, wherein, damping element 32 passes through the opening of annular boundary element 54
55 stretch out.Boundary element 54 can also realize the function of pure loss prevention device 54, and this causes that assembling becomes easy.Gauge unit
Part 54 is connected with the preferred flat side 40 of housing component 7.During depressed part extends to housing component 7 from side 40 in the case.
Design according to valve 1 can also set multiple damping units 31, and these damping units 31 are preferably with reference to the longitudinal axis
Line 9 is arranged with being distributed on periphery.
It is possible thereby to realize the axial movement of armature 4 with directional correlation damping.Direction (the damping edge of the determination
Realize in the direction for the determination) it is preferably closing direction 30.The unimpeded of the armature 4 when valve 1 is opened is thus achieved to add
Speed.Quick momentum structure facilitates valve 1 and reliably opens.In the case, have passed through armature free path in the operation of armature 4
After 19 and after the subsequent backstop of armature 4 is on interior pole 20, also may occur in which and needle 10 was put to a certain extent by armature 4
(Durchschwingen)。
When being moved along closing direction 30, armature 4 then passes through fluid damping and is braked.Arranged by damping element 32
Crowded fluid has to pass through the close clearance 35 that is preferably constructed in annular gap 35 and/or through throttling drilling and/or fills
Drilling 53 is overflowed, and armature 4 is slowed down during closing course.Gap 35 and/or the section of throttling and/or filling drilling 53
The spring force of the spring element 34 that stream is acted on and possibly serves for damping spring 34 if necessary can be realized and valve in the case
Dynamics is advantageously harmonious.Thus, it is possible to avoid pin resilience (Nadelpreller), less backstop momentum is realized
And realize the calmness faster of armature movement.Associatedly, it is also possible to realize less noise emission.
The present invention is not only restricted to described embodiment.
