- at least one injection channel 19 is arranged, in the closed position of the valve member 12 of the valve sealing surface 14 is closed and in the open position the valve member 12 via a between the valve member 12th and the bore 21 formed annular channel 16 with the pressure chamber 7 is connectable.
- a first closing spring 27th acted pressure rod 37 to the plant which is largely coaxial is arranged to the longitudinal axis 13 of the valve member 12 and formed into a valve holder body 1 in one Spring chamber 30 protrudes.
- FIG. 2 shows an enlarged detail of FIG. 1 in FIG Area of the washer 5 shown.
- the push rod 37 is smaller in diameter than the guided section the valve member 12, so that at the transition of the valve member 12 to the push rod 37 an annular shoulder 11 is formed is.
- the ring shoulder comes 11 of the valve member 12 to a stop sleeve 8 to the plant, which surrounds the push rod 37 and in the washer 5 is guided.
- stop sleeve 8 On the outer surface of the stop sleeve 8 is by a Cross-section reduction formed a stop shoulder 25, with the stop sleeve 8 at one in the washer 5 trained stop surface 26 during its stroke comes to the plant. This will be the maximum opening stroke limited the valve member 12. On the combustion chamber side comes the stop sleeve 8 with its end face 23 under the action the closing spring 28 on the end face 22 of the valve body 2 to the plant.
- a piston-shaped first adjusting bolt 31 arranged and about in the middle between the two ends of the spring chamber 30 a piston-shaped second adjusting bolt 32.
- the second adjusting bolt 32 has a central bore, which as Guide the push rod 37 is used.
- the adjusting bolts 31,32 are fixed by caulking in the spring chamber 30.
- spring plate 24 Between the first adjusting bolt 31 and one on the combustion chamber opposite End of the push rod 37 arranged spring plate 24 is the preferably designed as a helical compression spring first Closing spring 27 arranged under bias.
- the spring chamber 30 is over a formed in the valve holding body 1 leakage oil passage 36 with a drain line, not shown in the drawing connected.
- the wall of the spring chamber 30 is at the height of the first adjusting bolt 31 and at the level of the second adjusting bolt 32nd in each case at least one caulking bore designed as a blind hole 43 formed, which is a thin, easily deformable Residual wall 46 of the spring chamber wall forms.
- the adjusting bolts 31, 32 are one or more, formed circumferential annular webs into which the residual wall 46, between the bottom of the caulking 43 and the spring chamber 30 remains, is pressed.
- At the height of the brennraumabgewandten End of the adjusting bolt 31,32 is one each formed as a through hole Einstellbohrung 52 formed.
- FIG. 3 shows a section of FIG. 1 in the region of FIG first adjusting bolt 31.
- the combustion chamber side facing away from the Adjusting pin 31 is conical, whereby a chamfer 33 is formed.
- the Einstellbohrung 52 is in the radial direction to the center of the Valve holding body 1 formed out and forms with the axis the adjusting bolt 31 approximately a right angle.
- an adjustment tool 49 are introduced, with the part of the setting tool 49, which is inserted into the adjusting hole 52, approximately rod-shaped and bevelled at the end is.
- Figure 4 is an alternative embodiment of the Einstellbohrung 52, here an angle between 30 and 60 degrees, preferably 45 degrees to the axis of the adjusting bolt 31 has.
- the part of the adjustment tool 49, which in the Adjustment hole 52 is inserted, is rounded at its end trained and comes to the bevel 33 to the plant.
- the adjusting tool 49 By inserting the adjusting tool 49 in the direction of the adjusting bolt 31, the adjusting bolt 31 in axial Direction to the combustion chamber to move.
- Corresponding adjustment is made via the adjustment hole or adjustment holes 52 at the second adjusting bolt 32nd
- the combustion chamber facing away Side of the adjusting bolt 31 not conical, but form convexly curved in another form.
- the adjustment tool 49 is not, as shown in Figure 3, simply beveled form, but the bevel in another embodiment too realize, so that a slipping of the bevel on the Bevel 33 of the adjusting bolt 31 is possible.
- the supporting force on the adjusting bolts 31 or 32 can also be several adjustment holes 52 symmetrically the axis of the spring chamber 30 are arranged around and to Setting to be used at the same time.
- the operation of the fuel injection valve is like follows: At the beginning of the injection cycle, fuel gets under high pressure introduced through the inlet channel 4 in the pressure chamber 7. This results in the pressure shoulder 10 a resulting force in the axial direction away from the combustion chamber, because the valve member 12 through the first closing spring 27 via the push rod 37 with the valve sealing surface 14 on the valve seat 17 is pressed, opens the fuel injection valve only when the fuel pressure in the pressure chamber 7 the opening pressure has reached and the force on the pressure shoulder 10 is greater than the force of the first closing spring 27th By lifting the valve sealing surface 14 from the valve seat 17th the injection channel 19 via the annular channel 16 with the Pressure chamber 7 connected and fuel is in the combustion chamber injected.
- the closing of the fuel injection valve is characterized initiated that the fuel pressure in the pressure chamber 7 drops, until the force on the pressure shoulder 10 is no longer sufficient, counteract the force of the closing springs 27,28.
- the valve member 12 is over the stop sleeve 8 and the push rod 37 is accelerated in the direction of the valve seat 17, until the valve member 12 with the valve sealing surface 14 on the valve seat 17 comes back to the plant and the injection channel 19 closes.
- the first closing spring 27 caused opening pressure measured, whereupon the position of the adjusting bolt 21 or the set opening pressure can be corrected by the fact that the first Adjustment bolt 21 by means of the adjusting tool 49 in his axial position is shifted according to the measurement result. Is the measured opening pressure of the fuel injection valve Too large, the adjusting bolt 31 must away from the combustion chamber to be moved, it is too small, corresponding to the combustion chamber to. This procedure is repeated until the desired opening pressure set at the fuel injection valve is.
- the opening pressure continuously via a suitable device when moving the adjusting bolt 31 is measured.
- the adjusting bolt 31 is then in the manner described above by impressing the residual wall 46 of the caulking 43 in the spring chamber 30 caulked.
- the adjustment tool 49 from the Setting hole 52 removed and the adjustment hole 52 closed. This can be done, for example, that a steel ball is pressed into the adjusting hole 52. In the same way you proceed now in the positioning of the second adjusting bolt 32.
- the adjustment tool 49 instead of the adjusting force on the adjusting bolt 31,32 via a It is also possible for the adjustment tool 49 to be inclined be provided that the tool at his in the spring chamber introduced end has a cam-like Anformung. The Force on the adjusting bolt is then by twisting the Adjustment tool generated.
- the described method at to use a fuel injection valve wherein in the spring chamber 30 only one closing spring is arranged.
- more than two closing springs in the spring chamber 30th are arranged, whose opening pressure in the described Set way by moving an adjusting bolt can be.
