- a known fuel injection valve (DE 101 08 945 A1) has a sleeve-shaped nozzle body, which is closed by a valve seat body with an injection opening enclosed by a valve seat. in the
- Nozzle body is the injection port upstream of a valve chamber, which is in communication with a fuel inlet.
- the injection opening controlling valve needle which carries a forming a sealing seat with the valve seat closing head.
- the valve needle is acted upon at the end remote from the closing head needle end of a valve closing spring, which presses the closing head on the valve seat, so that the injection orifice
- Electromagnet causes the valve needle against the force of
- Valve closing spring to a stroke lifting the closing head of the valve seat drives.
- a magnetic flux is generated, which has an external pole, an internal pole, and an axial one on the valve needle
- Anchor stop for the anchor has. On the turn away from the driver Side of the armature, a second anchor stop is set on the valve needle, to which the armature is pressed by a between anchor and driver supporting Vorhubfeder.
- the electromagnet When the electromagnet is energized, the armature first executes a free travel or forward stroke on the valve needle until it abuts the driver on the first armature stop, thereby giving the valve needle a mechanical impulse and entraining the valve needle via the driver, whereby the closing head begins to move away from the valve seat withdraw.
- the armature At the end of the complete armature stroke, the armature abuts against the pole face of the inner pole and the ejection opening is fully released, so that the in the
- Valve chamber pressurized fuel is sprayed through the spray orifice in a metered amount.
- Electromagnet pushes the valve closing spring over the valve needle
- valve according to the invention for metering fluid with the features of claim 1 has the advantage that, as an additional inner pole, the force with which the armature strikes the inner surface of the inner pole at the end of its stroke is reduced, so that that too
- Impact sound of the armature is much lower. It is ensured that the impulse imparted by striking the armature against the stop shoulder of the driver of the valve needle in the direction of valve opening is not reduced in its strength.
- the reduction of the subsequent armature impact on the inner pole causing magnetic force is achieved in that at the end of the Vorhubs of the anchor with abutment of the armature to the driver of the part of the magnetic flux, which runs over the gap resting on the armature carrier, no contribution to the remaining in the Working air gap between armature and inner pole effective magnetic force makes. With the thus reduced magnetic force in the remaining part of the working air gap, the armature is pulled to the pole face of the inner pole and beats gently and less noisy on the inner pole.

- the armature has an inner region surrounding the valve needle of a magnetically non-conductive material, that is, a material with a low magnetic
- the inner region of the armature has the shape of a straight circular truncated cone with an annular top surface facing the driver and an annular base facing away from the driver and enclosing the inner region Outside has the shape of a cylindrical ring with a frusto-conical inner ring wall. It is advantageous that the outer diameter of the annular top surface is slightly larger than the outer diameter of the valve needle and the
- Outer diameter of the annular base is little smaller than the outer diameter of the armature.

- FIG. 2 shows an enlarged view of section II in FIG. 1
- FIG. 3 is a view similar to that in FIG. 2 when the electromagnet is energized after a first lifting phase of the armature
- FIG. 4 is the same as in FIG. 2 when the electromagnet is energized after a second lifting phase of the armature
- Figure 5 is a same view as in Figure 2 with a modification of the armature.
- Metering of fluid is preferably used as an injection valve for injecting fuel in a fuel injection system of internal combustion engines.
- the valve has a standing with a fluid inlet 1 1 in connection
- Valve closing spring 14 is actuated.
- the closing head 131 is in one
- Valve seat body 16 out, the metering opening 12 and a the
- Enclosing opening 12 enclosing, with the closing head 131 of the valve needle 13 has a sealing seat forming valve seat 17.
- the valve seat body 16 closes off a kanness workedes end of a sleeve-shaped valve housing 18 in a fluid-tight manner, while in the inlet-side other end of the valve housing 18, a fluid inlet 11 containing the connecting piece 19 is inserted.
- the electromagnet 15 has a magnetic coil 20, which can be supplied with current via a connector, not shown, on the valve. When energizing the
- Magnetic coil 20 forms in the electromagnet 15, a magnetic flux, which is an outer pole 21, a hollow cylindrical inner pole 22, an armature 23 which is axially displaceable on an armature guide portion formed on the valve needle 13, and one of armature 23 and inner pole 22 limited
- a driver 25 is fixed, e.g. welded, which is axially slidably immersed in a driver in the hollow cylindrical interior of the inner pole 22 driver guide portion 221.
- the driver 25 has a radial abutment shoulder 251 for the armature 23, which limits a smaller freewheel or Vorhubweg 26 of the armature 23 in relation to the axial gap width of the working air gap 24 (FIG. 2).
- Vorhubweg 26 of the armature 23 is by an anchor stop 27, which on the from the driver 25 side facing away from the armature 23 is fixedly disposed on the valve needle 13, and a Vorhubfeder 28 set, which presses the armature 13 to the anchor stop 27.
- the valve needle 13 loosely enclosing, cup-shaped spring plate 29 is fixedly disposed on the armature 23 and is executed for example as a helical compression spring Vorhubfeder 28 so on the
- the driver 25 is formed into an additional inner pole with one of the stop shoulder 251
- the driver 25 is magnetically conductive, so it consists of a material with low magnetic Wderstand, and between an armature 23 and valve needle 13 effective magnetic flux barrier is provided by means of a magnetically non-conductive material, ie a material with a very high magnetic resistance, a Magnetic flux between armatures
- valve needle 13 is wholly or at least in their the armature guide portion 132 having
- valve needle 13 either entirely or at least in its
- Anchor guide portion 132 having needle portion of a magnetically conductive material and the armature 23 has a valve needle thirteenth
- Exterior 232 of a magnetically conductive material is exterior 232 of a magnetically conductive material.
- Interior portion 231 of the armature 23 is preferably in the shape of a straight
- Base 231 b are the same size, but the outer diameter of the top surface 231 a is significantly smaller than the outer diameter of the base 231 b.
- the outer diameter of the annular top surface 231a little larger than the outer diameter of the valve needle 13 and the
- Outer diameter of the annular base 232b is slightly smaller than the outer diameter of the armature 23.
- the outer portion 232 of the armature 23 has the shape of a cylindrical ring with a frusto-conical inner ring wall whose course corresponds to the outer contour of the inner region 231.
- the armature 23 according to FIG. 5 is preferably produced as a two-component component made of a material having a high magnetic resistance and a material having a low magnetic resistance.
- the electromagnet 15 is de-energized and the metering opening 12 is closed by the valve closing spring 14 acting on the driver 25 pressing the closing head 131 of the valve needle 13 onto the valve seat 17.
- the annular working air gap 24 with the axial gap width s is present.
- the armature 23 is pressed by the Vorhubfeder 28 to the anchor stop 27, so that 25 sets a gap for a free path or Vorhubweg 26 of the armature 23 with an axial gap width f between the end face of the armature 23 and the stop shoulder 251 of the driver.
- the magnetic coil 20 of the electromagnet 15 energized, so the magnetic flux generated by the magnetic coil 20 in the armature 23 is divided into two paths, the first path via the armature end face directly to the inner pole 22 and the second path on the armature end face for addition - Pole, so the driver 25 runs. Since the gap width f is smaller than the gap width s, a larger magnetic force in relation to the pole face is possible in the second path. As a result, the armature 23 during energizing the
- Anchor stop 27 accelerates.
- the magnetic flux barrier of magnetically non-conductive material between the armature 23 and valve needle 13 prevents a transfer of the magnetic flux into the valve needle 13 and thus a magnetic short circuit via valve needle 13 and driver 25th
- the accelerated from its basic position anchor 23 moves due to the magnetic force generated by the magnetic flux in the direction of the inner pole 22 and first strikes against the stop shoulder 251 of the driver 25 ( Figure 3).
- the distance between the armature end face and the inner pole 22 has been reduced to the gap width s-f.
- Pole 22 acts, is reduced, since by the contact between armature 23 and driver 25, the magnetic flux in the second path now on the one hand increases and on the other hand does not contribute to the valve opening magnetic force.
- Anchor 23 from its basic position on the anchor stop 27. As a result, the armature 23 strikes with significantly lower force on the inner pole 22, which leads to a noise reduction. If the armature 23 lies without a gap in the inner pole 22, then the magnetic force between armature 23 and inner pole 22 is increased again. The over the armature 23 to the driver 25 and the inner pole 22 leading part of
- Magnetic flux can not be used to hold the valve open (FIG. 4).
- the inner pole 22 is structurally formed by a hollow cylindrical magnet core 30 fixed in the valve housing 18 and the outer pole 21 by a magnetic cup 31 with magnetic return 32 enclosing the valve housing 18 in the region of the magnetic core 30 and armature 23.
