Definitions
- the invention relates to a laminated armature for an electromagnetic actuator and an injection valve for metering a fluid, comprising an electromagnetic actuator with such a laminated magnet armature.
- Injection valves are used for the controlled metering of a fluid, for example the injection of fuel into the intake tract or into the combustion chamber of a combustion engine.
- the control of the injection valve can take place via an electromagnetic actuator, which has for this purpose an energizable coil and a magnet armature made of a ferromagnetic material.
- an electromagnetic actuator which has for this purpose an energizable coil and a magnet armature made of a ferromagnetic material.
- a magnetic field builds up inside the coil, through the action of which the ferromagnetic magnetic armature can be moved.
- Coupled to the armature is a valve needle, which can be moved by the magnetic interaction between the coil magnetic field and armature in the outlet of the injector releasing or closing position, so that a ⁇ to beessendes fluid, such as fuel, are delivered in a controlled manner can.
- an electromagnetic actuator with laminated armature which is constructed as a plate pack of a plurality of firmly interconnected laminations, wherein the laminations are arranged between two cover plates and aligned perpendicular to them.
- One Disadvantage here is the complex production of such an arrangement.
- Magnet armature for an electromagnetic actuator specified, wherein the armature is displaceable along an axis A in a direction of movement, comprising a plurality of interconnected sheets, wherein the sheets aligned perpendicular to the axis A and in the direction of movement of Mag ⁇ netankers to a sheet stack with a bottom and a top are stacked.
- Each sheet has at least one recess which is open towards an edge of the sheet, wherein the sheets are arranged within the sheet stack such that at least one channel extending from the underside to the top through the stack of sheets is formed by the recesses.
- it is inventively provided to produce the armature of a plurality of sheets, which are stacked in the direction of movement of the armature.
- the planes - these are in particular the main extension planes - of the individual sheets are therefore perpendicular to the direction of movement of the armature or the surface normal of the individual sheets is parallel to the direction of movement of the magnet armature.
- the sheets are particularly flat disks, sometimes referred to as plane-parallel plates.
- the sheets are stacked "to form a stack of sheets” in this context means, in particular, that the sheet stack consists of the sheets.
- the sheets are stacked to form the stack of sheets, that is, follow each other in the direction of the axis
- the main surfaces are, in particular, the opposite surfaces of a respective metal sheet parallel to the main plane of extension, in other words the main surfaces of a metal sheet are those portions of its surface, that of the metal sheet in the axial direction
- Each plate has at least one recess open towards one edge of the plate, which serves to suppress, or at least reduce, eddy currents in the plates
- Sheets are arranged one behind the other in such a way that at least one passage extending from the bottom to the top through the stack of sheets is formed by the recesses.
- the individual sheets may be arranged such that their recesses all and completely cover. In this way, a number of channels determined by the number of recesses per sheet is formed within the sheet stack, through which the fluid to be metered can flow. By means of the channel or the channels, a particularly large hydraulic diameter can be achieved in the region of the magnet armature.
- a circulating around the plate peripheral surface is understood in the present context.
- ⁇ particular limits the circumferential surface of the metal sheet in the radial direction from the axis A away.
- the fact that the recess of a sheet “to an edge of the sheet is open ", as used herein means in particular that the circumferential sheet metal around the circumferential surface has openings, from which the depending ⁇ stays awhile recess radially extends inwardly into the sheet.
- the recesses are slit-shaped in the sheets.
- the slots can be arranged, for example radially from the edge of the sheet to the center to ⁇ running.
- the recesses in the sheets may also be formed in a nearly circular manner, thereby enabling a particularly good passage for the fluid to be metered.
- a combination of circular recess and slot is conceivable, for example, one from the edge of the sheet inwards -.
- the number of sheets used for the magnet armature according to the invention is preferably between 5 and 15.
- the sheet stack has on the top and / or on the bottom of a sheet metal disc, which is made of a material which has a greater hardness than the material of the sheets.
- the inside of the stack of sheet metal to extremely arranged plates hit when moving the armature to surrounding components - for example, to the movement of the
- sheet metal discs greater hardness on the top and / or on the bottom the tendency of the magnet armature wear can be favorably influenced and it can be dispensed with the otherwise conventional chromium plating.
- a material for the harder sheet metal discs for example, SS302 hard-rolled stainless steel can be used.
- the connection of the individual sheets takes place according to an embodiment in the form of material, for example by
- welding in particular laser welding, soldering or similar joining techniques.
- the individual sheets are stacked in the desired arrangement and there are applied to the outer wall of the thus constructed magnet armature and distributed over the circumference of several welds.
- a material connection of the individual sheets may fundamentally ⁇ additionally also take place by gluing.
- the connection of the individual sheets can also be effected by adhesion and / or positive locking.
- each sheet 2 to 10 recesses open towards the edge of the sheet.
- the number of recesses and their size to take into account that on the one hand the flow must be given for the fluid to be metered, on the other hand, a sufficient sheet surface must remain to both the stability of the individual sheets and the sufficient magnetic interaction between the magnetic field of the coil and to ensure the magnet armature.
- the number of recesses may also depend on their size. Also, it is conceivable that not all sheets within the
- Sheet metal stack have the same number and / or shape of open to the edge recesses. However, it must always be ensured that at least one passage for the passage of fluid through the sheet stack is formed by the existing recesses.
- the recesses of a sheet can be distributed evenly or non-uniformly over the surface of the sheet.
- the individual sheets themselves, which are stacked on the magnet armature on ⁇ moreover, not necessarily all have the same shape.
- metal sheets with a smaller area can be provided within the sheet stack, whereby the total weight of the armature is advantageously reduced. A reduction of the area can be effected, for example, by a central recess within the sheet, so that the sheet has a more circular shape. It should, however, keep in mind that sufficient material remains to ensure ei ⁇ nedeem the stability of the sheet and on the other hand, the mag- netic coupling.
- a central recess provided in this way could also be further widened within the sheet stack, ie the diameter of the central recess could be in the stacking direction increase or decrease from plate to plate.
- a weight reduction of the armature can also be effected in that the individual sheets consist of several circular rings of different diameters, which are connected to each other via spoke-like connecting webs, wherein the recesses open towards the edge can in principle be arranged in each of the circular rings.
- the production of the individual sheets is carried out according to an aspect of the invention by punching from corresponding metal plates.
- the sheets may be arranged offset from one another within the sheet stack in such a way that at least one spiral-shaped channel extending from the underside to the upper side is formed by the recesses.
- a spiral-shaped or spiral-like channel is understood here and below to mean a channel whose course follows a helical line, but at least a section of a helix.
- the recesses of the individual sheets are not brought exactly to coincidence in this embodiment of the invention, but successive sheets are arranged within the stack by an angle ⁇ against each other twisted, so that their recesses overlap only partially and in this way by the entirety of the recesses formed channel has a spiral-like course.
- an injection valve for metering a fluid comprising an electromagnetic actuator having the described magnetically fixed armature.
- FIG. 1 is a schematic sectional view of an injection valve according to the prior art
- Figure 2 is a plan view of a sheet of a magnet armature according to an embodiment of the invention.
- Figure 3 is a schematic side view of a laminated Mag ⁇ netankers according to an embodiment of the invention.
- FIG. 1 shows an injection valve 1 known from the prior art, as for example for injecting
- Fuel is used in the intake tract or in the combustion chamber of an internal combustion engine.
- the injection valve 1 has a fluid inlet end 1a and a fluid outlet end 1b and comprises a valve housing 2 which surrounds a cavity 3. Within the cavity 3, a valve needle 4 is arranged. The valve needle 4 is displaceable relative to the valve housing 2 along an axis A.
- the valve needle 4 has, at its end facing the fluid outlet end 1b of the injection valve 1, a closure element 5 designed as a ball, with which the valve needle 4 can be received in a valve seat 6.
- the valve seat 6 has an opening 7, which can be released or closed by the closing element 5 of the valve needle 4. If the valve needle 4 is moved into a position releasing the opening 7, then a fluid to be metered can emerge from the injection valve 1 through the opening 7.
- valve needle 4 If the valve needle 4 is in a position closing the opening 7, no fluid can escape from the injection valve 1.
- the valve needle 4 can be biased into a position closing the opening 7, so that the valve needle 4 is pressed with its designed as a ball closing element 5 in the valve seat 6 and the opening 7 closes.
- a calibration unit 12 is provided to set a required spring tension of the valve spring 8.
- the injection valve 1 has an electromagnetic actuating device which contains a magnetic coil 9 and a magnet armature 10.
- the solenoid coil 9 surrounds a portion of the valve housing 2 concentrically.
- a magnetic field builds up inside the magnetic coil 9, the orientation of which can additionally be influenced by a pole piece 11.
- the existing of a ferromagnetic material magnet armature 10 is disposed within the Ventilge ⁇ housing 2 in the cavity 3 and mechanically coupled to the valve needle 4. He is like this or together with this along the axis A in a predetermined by this direction of movement relative to the valve housing 2 slidably.
- FIG. 1 shows two channels 13 passing through the magnet armature 10. These serve for the passage of the fluid, here fuel, from the region of the fluid inlet end 1a through the magnet armature 10 into the region of the fluid outlet end 1b.
- Magnetic anchors known from the prior art such as the armature 10 in Figure 1, are e.g. in sintering technology or as solid components turned and drilled out of the bar.
- the magnet armature 10 is constructed as a laminated magnet armature of individual sheets 14, of which in FIG. 2 a sheet metal 14 according to an embodiment of the invention is shown.
- the circular plate 14 is obtained by punching from a corresponding metal plate.
- the sheets 14 follow one another positively along the axis A, so that the mutually facing main surfaces of successive sheets 14 adjoin one another.
- the sheets 14 are connected to each other by means of a laser welding process, for which purpose a plurality of weld seams 19 are applied to the outer wall of the magnet armature 10 and distributed over its circumference. After the laser welding process has been carried out, the metal sheets 14 in the finished armature are therefore also connected by a material fit by means of the weld seams 19.
- the weld seams 19 extend in the axial direction over a plurality of sheets 14, in the present case they extend parallel to the axis A and connect all the sheets 14 to each other.
- the individual sheets 14 each have a central, circular ⁇ shaped recess 15 through which the valve needle 4 can be passed.
- the recess 15 is positioned the same for all sheets 14, so that when stacking the individual sheets 14 to the armature 10, a central receiving channel for the valve needle 4 is formed.
- the valve needle 4 is connected in the region of these recesses 15 with the sheets 14, whereby the above-mentioned mechanical coupling between the valve needle 4 and armature 10 is effected.
- the individual sheets 14 are thus stacked in the direction of movement of the armature 10, i. the sheets 14 are oriented substantially perpendicular to the axis A.
- the surface normals of the major surfaces of the sheets 14 are parallel to the axis A.
- the plate 14 shown in Figure 2 four further recesses 16, which are arranged distributed uniformly over the circumference of the sheet 14 and the edge 17 of the sheet 14 are open. That is, the recesses 16 open in radially outward direction in the edge 17 forming peripheral surface of the respective sheet.
- the recesses 16 are initially formed slot-shaped starting from the edge 17 of the sheet 14 and then widen in the direction of the recess 15 towards circular.
- the recesses 16 are used for a fuel flow within the injection valve 1, on the other hand, but they also have the function of eddy currents, which are induced by the construction or degradation of the magnetic field of the magnetic coil 9 in the sheets 14 of the armature 10 to suppress or at least redu ⁇ decorate.
- the stacking of individual sheets 14 to the laminated magnet armature 10 can be done in different ways.
- similar sheets 14 can be stacked one above the other so that their recesses 16 all come to cover.
- four channels 18 are formed within the sheet stack through the recesses 16, which are parallel to the through the recesses
