Seamed edge 34a processed（Left side in the accompanying drawings）With the second control seamed edge 34b（Right side in the accompanying drawings）, the control seamed edge and described first
Be open 28b synergies.
In addition it can also see that the first space 36 in the side face 37 of the collar 26b and form are the shell in fig. 2
The Second gap 38 of circular groove in the wall 39 of the inner radial of body 12.The Second gap 38 is in the accompanying drawings in described the
On the right side of one opening 28b and therefore relative to the described first opening with small spacing（Without reference）It is disposed adjacent to.Institute
The spacing 40 stated between the first space 36 and the control seamed edge 34b for pointing to Second gap 38 is less than the Second gap 38
Axial extension 42.
First space 36 be configured to radially around groove.The Second gap 38 can be configured to radially around groove
Or it is configured to axial notch.Current sectional view is applied to described two embodiments in principle.The first opening 28b
Described second opening 28c between in the pressure relieving position of the valve element 22（Referring to Fig. 3）The through-flow horizontal stroke of the hydraulic pressure to work
Section, to radially around groove for it is general bigger than for axial notch.
In the axial location shown in figure 2 of the valve element 22, the two control seamed edge 34a and 34b respectively with
Small radial clearance is abutted on the wall 39 of the inner radial of the housing 12.Therefore the first opening 28b is hydraulically blocked
（Working joint）.The electric current flowed through the coil 16 of the actuator 14 is for example with the control electricity in the actuator 14
" first " current value within the scope of stream.If by with（Than first current value）Slightly smaller electric current manipulates the actuator
14 mode causes the valve element 22 to move less yardstick axially towards the actuator 14 from shown position, and that is just
Can be as established hydraulic connecting between the described first opening 28b and the 3rd opening 28a figure 3 illustrates as.Institute
This position for stating valve element 22 is referred to as pressure relieving position.
If by with（Than first current value）Slightly larger electric current manipulates the actuator 14 and causes the control rib
The mode in the left side of right side edges of the side 34b in the accompanying drawings in the described first opening 28b, to cause the valve element 22 from shown
The position gone out is axially distant from the actuator 14 and moves less yardstick, that just can described first opening 28b with it is described
Hydraulic connecting is established between second opening 28c.Control of these schemes corresponding to the guiding valve 10 with reference to the described first opening 28b
Operation.If the electric current flowed through the coil 16 is adjusted to maximum, then the valve element 22 will stop in the accompanying drawings
Lean against left side and therefore occupy（" second "）Terminal location.
Fig. 3 shows the interception part II of Fig. 1 in already mentioned pressure relieving position above the valve element 22.Institute
State pressure relieving position and be in second terminal position described above and " first " terminal location during 16 no current of coil（Ginseng
See Fig. 4）Between.Herein the actuator 14 is manipulated with the second smaller than previously given threshold value but bigger than zero electric current.By
This can be such that the valve element 22 is moved with bigger amplitude towards the actuator 14 by the power of the helical spring 25.This institute
The threshold value for stating electric current refers to that the control shown in figure 2 runs the critical condition between Fig. 3 pressure relieving position.Such as institute
Valve element 22 is stated to arrange in the state by Fig. 3 on the right side of in the accompanying drawings（" first "）About 1mm on the left of terminal location（Millimeter）Place.
The threshold values being previously mentioned of the electric current is, for example, 300mA（Milliampere）.
, it can be seen that hydraulic connecting be present between the described first opening 28b and the second opening 28c in figure 3.This
It is possible, because the spacing 40（Referring to Fig. 2）Less than the axial extension 42 of the Second gap 38.More precisely,
Hydraulic pressure cross section described in the state by Fig. 3 of the valve element 10 in the region of Second gap 38 is relative in " normal " control
Possible cross section is smaller in system operation.Nevertheless, the cross section with other situations caused by drawn due to tolerance
It is rising and caused by the function, between the wall 39 of inner radial and the side face 37 of the collar 26b of the housing 12
Radial clearance is compared to bigger.
It is still able in this way in shown pressure relieving position faster in the described first opening 28b and institute
State and realize hydro-cushion between the second opening 28c, if alreadyed switch off to the described second opening 28c simultaneously（Input adapter）Feed
Hydraulic pump if.In addition, the 3rd opening 28a described in Fig. 3 state and the described first and second opening 28b and 28c liquid
Pressure connection, comprehensively realizes hydro-cushion, that is to say, that equilibrate to and be present at the out splice going splice 28a so as to so-called
Than relatively low stress level.
Fig. 4 shows the interception part II of Fig. 1 in the inactive state in the valve element 22.The actuator 14 is herein
Not with electric current come manipulate and the valve element 22 thus by the power of the helical spring 25 drive in the case of be in attached
Right side in figure（" first "）In terminal location.Said control seamed edge 34b abuts in the shell with the clearance of small radial direction
On the wall 39 of the inner radial of body 12, thus substantially block between the first opening 28b and the second opening 28c
Hydraulic connecting.
Due to the release carried out before this according to Fig. 3 between the working joint and input adapter of the guiding valve 10, by Fig. 4
State in there is no that flow of pressurized passes through the radial clearance.Pollution for the wall 39 of the inner radial of the guiding valve 10
And the space formula filtering being previously mentioned is minimum or not existed even.
If implement the control operation of the guiding valve 10 again again after Fig. 4 inactive state, then, if flowed through described
The electric current of coil 16 exceedes the previously given threshold value fast enough, and that just can be accordingly soon continuously across showing in figure 3
The pressure relieving position gone out.Short time and less flow of pressurized between the first opening 28b and the second opening 28c exists
This is typically small or does not interfere with all.
In addition, to respectively illustrate the valve element 22 left in the accompanying drawings by Fig. 3 pressure relieving position relative to valve element 22 by Fig. 2 and 4
The adjacent position on the right side in other words of side.It is described two in the adjacent position of the both sides relative to the pressure relieving position
Be open the mutual hydraulic pressure separatings of 28b and 28c.But can be as above according to the electric current of the flowing of coil 16 through the actuator 14
Liquid is realized with larger cross section between the opening 28b and 28c in the control operation by Fig. 2 as described in face
Pressure connection.The valve element 22 and especially described space 36 and 38 are so formed herein, so as to outside the pressure relieving position by Fig. 3
The guiding valve 10 has less leakage, and this is similar with the situation in the known embodiment before the guiding valve 10.
Fig. 5 is shown for a kind of flow chart for being used to run the method for the guiding valve 10.Start in initial block 44
The process shown in accompanying drawing.The guiding valve 10 described in ensuing square frame 46 has the inactive state by Fig. 4.Here, especially exist
It is not powered when motor vehicle is not in operation to the actuator 14.That is this state being capable of last longer.
In ensuing square frame 48, also the actuator 14 is led to after the internal combustion engine of the motor vehicle is started
Electricity, wherein electric current are climbed to the first electric current higher than the threshold value.It is corresponding soon continuously across the valve element 22 herein
Pressure relieving position and the guiding valve 10 in being run by Fig. 2 control thus, it is possible to run.The control operation can equally be held
The continuous long period.
In ensuing square frame 50, just the motor vehicle internal combustion engine motor vehicle fluid drive in other words in other words is being cut off
Device is powered the shorter time in the time interval before hydraulic pump with second current value to the actuator 14 in other words,
Second current value is less than the previously given threshold value but is greater than zero.Described in being realized herein within the shorter duration
Valve element 22 presses Fig. 3 pressure relieving position.It is preferred that the length of the time is so designed that, so as in the described first opening 28b（Work
Make joint）With the described second opening 28c（Input adapter）Between and relative to the described 3rd opening 28a（Out splice going splice）Carry out
Hydraulic pressure balances.
To illustrate herein, can also skip methods described in the square frame 50 if necessary, method is from the control fortune
