Definitions
- the present invention relates to an electromagnetic actuator device according to the preamble of the main claim.
- Such a device is for example from the JP 2000 170951 A is known and relates to an electromagnetic actuator device for implementing a 3-way valve, in which, in departure from the usual and beyond known as vortex actuator technologies, the coil winding does not surround the armature (or the associated working air gap), but the coil winding, in the Type of "outsourced coil” is offset laterally relative to an armature movement longitudinal axis (or an associated air gap) and a magnetic flux transfer to the armature unit or to the air gap by means of suitable flux-conducting portions of the yoke.
- JP 2000 170951 A in a very special technical context, which in particular makes a transfer to other, generic actuating tasks (or else to other valve drives) only possible to a very limited extent.
- the known from this prior art device requires a not inconsiderable space, in addition, a heat dissipation from the known device is not without problems.
- Object of the present invention is therefore to provide an electromagnetic actuator according to the preamble of the main claim, wherein a Bestrombare coil unit encloses a first yoke portion of a stationary yoke unit and relative to the yoke unit movably guided, cooperating with a control partner and drivable for performing an actuating anchor means a second yoke portion of the yoke unit to form the working air gap cooperate to improve in terms of a more compact, and in particular more flexible mechanical realization, in particular to provide the ability to separate the coil unit from the working air gap, and the ability to create an improved To realize heat dissipation or heat to be distributed locally (and thus less concentrated on one place).
- the coil unit is realized in the form of a plurality of separate, yet magnetic flux interconnected individual coils, which according to further preferred embodiments of the invention then in solution a locally distributed arrangement each (smaller to be dimensioned and thus also potentially less heat-generating) individual coils allow their respective magnetic flux then cumulatively for the common anchor (or the associated working air gap) merged and added so far.
- the working air gap or the at least one air gap provided within the scope of the first aspect of the invention is / are formed outside the first yoke section, ie is not enclosed by a coil unit (typically cylindrical or rectangular in design) but instead is laterally outsourced in the sense discussed above.
- a coil unit typically cylindrical or rectangular in design
- each of the flux circuits by the (common coil carrying) first yoke portion and via a respective one of the plurality of anchor units associated air gaps is a magnetic flux resistance of Flußleitschn of at least one of the magnetic flux control circuits in response to a flowing magnetic flux therein variable.
- the consequence of this effect is that a magnetic flux is then displaced from the relevant flux circuit into another of the flux circuits, insofar as an armature movement can then be triggered or influenced.
- presetting or predetermined influencing of the movement behavior of the plurality of anchor units is to design the air gaps differently (in each case based on a predetermined, comparable anchor position, for example a stop position of the anchor units).
- Another way to influence the switching or movement behavior of a respective armature unit of the anchor means is to associate this armature spring means or the like power storage and about further education to store one or more of the armature units against a restoring force of such a spring or lead (where in turn further education by different configurations such as the spring forces then the respective switching or movement behavior of the associated anchor units can be influenced in a predetermined manner).
- the electromagnetic actuator device according to the second aspect of the invention, according to which a plurality of individual coils (in potentially small installation space) suitably arranged adjacent to the second yoke section with the working air gap, so that the working air gap lies between the individual coils, advantageously provides that at least one of the individual coils, more preferably, all of the individual coils extend parallel to a direction of movement of the armature unit, so that, for example, when arranging the individual coils around the working air gap around, a particularly compact unit can be created, which nevertheless must have no symmetry.
- the present invention also makes it possible by the variability described to optimize one (or, in the case of several individual coils, several) effective cross-sectional areas of the first yoke section, so that, for example, the coil unit provided thereon (with regard, for example, to the copper weight of the winding) can be optimized ,
- suitable provided Flußleitstoff in the form of suitable elements can be as a specific purpose (or respective site and the applicable installation conditions) implemented low-priced construction structures:
- these flux-conducting elements are flat or planar elements, which are furthermore advantageous approximately both sides of central axes of both the plurality of coil devices, as well as the second yoke portion (with the working air gap) are provided for flux-conducting connection thereof, so again a simple and mass production manufacturable, nevertheless optimized in terms of a space utilization arrangement arises (in particular also constructive There are possibilities to make thermal optimizations).
- the space-optimized (and, for further training, approximately angled) space-saving geometry realized by means of the flat or flat flux-conducting means is also analogous can be provided for implementation forms, in which about the end of the flux guide anchor units (with a respective working air gap) are provided suitable, while in a central region, the common coil unit is provided.
- the electromagnetic actuator device according to the invention is indeed preferably for the realization of hydraulic or pneumatic valve solutions, especially in the vehicle sector, but is not limited to these applications.
- the present invention can be used favorably and suitably configured for virtually any field of application in which structural or spatial flexibility can be used in conjunction with flexibly configurable magnetic flux guides or flow paths within the respective flux guide circuits.
- the Fig. 1 illustrates in the schematic longitudinal sectional view of an electromagnetic actuator device for driving two anchor units 10, 12 by means of a common, centrally located (centrally) between them on a yoke section 13 coil unit 14. More specifically, as schematically with reference to the graph of Fig. 1 recognizable, the elongated armature units 10 and 12 shown axially movably guided (in a movement and drive direction perpendicular in the plane), wherein the armature units 10 and 12 cooperate with stationary yoke sections 15 and 16 and, for the realization thereof, together by the coil unit 14 extending flow control circuits, which are guided over flow-conducting connection sections 18 to 24. Accordingly arise for the anchor units 10 and 12 effective air gaps 26 and 28 respectively.
- the Fig. 2 to 4 illustrate various operating conditions in response to energization of the coil unit 14: So shows about the Fig. 3 two flow paths in the flux guide circuits running through the respective armatures 10 and 12, respectively, on the basis of the arrowheads 30 and 32, these magnetic fluxes flowing through the yoke section 13 ("first yoke section") associated with the coil unit 14, as symbolized by the arrowhead 34. Is against it, as in the Fig. 2 shown by a shortened air gap 28 an effective flow resistance in the right flux guide circuit (ie with respect to the armature unit 12) is reduced with respect to the other arm, the magnetic flux concentrates as indicated by the arrowhead 36 in FIG Fig.
- this simplest embodiment already realizes an inventive principle of the outsourced armature, namely an armature provided within a flow circle branch and laterally or adjacently arranged (including the associated air gap), so that an armature movement direction while further education parallel to an extension direction of the coil unit (or the associated first Jochabitess) can take place, but these axes are no longer coaxial.
- FIG. 5 A first variant illustrates the Fig. 5 in the perspective view: on both sides of an axially movable armature 40 and a stationary yoke portion 42 having central arrangement, a pair of individual coils 44 and 46 is provided such that armature 40 and stator 42 are framed on both sides of the individual coils 44, 46.
- a magnetic flux (resulting when the coils are energized) of the coils 44 and 46, respectively, is fed into the armature 40 or the stator 42 via common elongated plate-shaped flux conducting elements 48 and 50, the elements 48 and 50 additionally being used for a mechanical connection the overall arrangement (with an outlet opening 52 for the anchor unit) provide.
- two flux guide circuits are formed, wherein a respective one of the flux circuits runs through one of the individual coils 44 and 46 and both flux circuits then flow together through the armature-stator arrangement 40, 42 (insofar the flow path corresponds analogously of the Fig. 3 but with a provision of a central armature-stator arrangement and two external individual coils).
- This basic configuration of the Fig. 5 is, however, not limited to two individual coils, nor about the symmetrical arrangement shown; rather, by varying the geometry of the elements 48, 50, a change in distance can take place, it can also, as in the Fig. 6 to 8 clarifies, one opposite the elongated elements 48, 50 suitably kinked configuration, or there may be more than two individual coils to one (or even more) common armature-stator assembly (s) around provided: So describes about the Fig. 6 in plan view, a variation of the elements 48 and 50, such that now two legs 54, 56, angled away from each other by an angle 58 of about 135 °, extend and end, compare Fig.
- FIG. 7 A comparison arrangement of the presupposed as known, traditional type in the representation of Fig. 7 illustrates the resulting installation space or geometry advantage: namely, in order to produce a magnetic flux behavior comparable to the pair of individual coils 44, 46, a single coil of a winding cross-section 60, as in FIG Fig. 7 indicated to be present, but possibly in a limited installation space (adapted to the configuration of Fig. 6, 8 ) not possible.
- a further advantage of the solution according to the invention with a plurality of individual coils provided adjacent to an armature-stator arrangement with an adding or overlapping flow profile, such as in FIG Fig. 5 respectively. 6 and 8 shown, is that possible lateral forces are reduced (to the anchor) compared to a solution with only one adjacent the anchor unit outsourced coil (as far as a mutual compensation takes place, see for example the flowchart of Fig. 3 in analogous application to an arrangement with two external individual coils).
- a reduction of the lateral forces on the anchor has a favorable effect on wear and therefore an effective service life.
- the present invention offers numerous practical advantages: For example, arranging one (or more) armature unit (s) in a use as a valve offers significantly more flexible connection possibilities in the configuration according to the invention adjacent to the coil unit (s) Coil units), as compared to the known prior art, in which typically the elongated armature unit is surrounded by the coil unit (typically cylindrical-radial). Accordingly, the working air gap can be made more flexible (and suitable for a particular application).

Description
Die vorliegende Erfindung betrifft eine elektromagnetische Aktuatorvorrichtung nach dem Oberbegriff des Hauptanspruchs.The present invention relates to an electromagnetic actuator device according to the preamble of the main claim.
Eine derartige Vorrichtung ist beispielsweise aus der
Allerdings erfolgt die Offenbarung gemäß
Aufgabe der vorliegenden Erfindung ist es daher, eine elektromagnetische Aktuatorvorrichtung nach dem Oberbegriff des Hauptanspruchs zu schaffen, bei welcher eine bestrombare Spuleneinheit einen ersten Jochabschnitt einer stationären Jocheinheit umschließt und relativ zur Jocheinheit bewegbar geführte, mit einem Stellpartner zusammenwirkende und zum Ausführen einer Stellbewegung antreibbare Ankermittel mit einem zweiten Jochabschnitt der Jocheinheit unter Ausbildung des Arbeitsluftspaltes zusammenwirken, im Hinblick auf eine kompaktere, insbesondere auch flexiblere mechanische Realisierung zu verbessern, dabei insbesondere die Möglichkeit zu schaffen, die Spuleneinheit vom Arbeitsluftspalt zu separieren, und die Möglichkeit zu schaffen, eine verbesserte Wärmeabfuhr zu realisieren bzw. Wärme lokal verteilt (und damit weniger auf einen Ort konzentriert) entstehen zu lassen.Object of the present invention is therefore to provide an electromagnetic actuator according to the preamble of the main claim, wherein a Bestrombare coil unit encloses a first yoke portion of a stationary yoke unit and relative to the yoke unit movably guided, cooperating with a control partner and drivable for performing an actuating anchor means a second yoke portion of the yoke unit to form the working air gap cooperate to improve in terms of a more compact, and in particular more flexible mechanical realization, in particular to provide the ability to separate the coil unit from the working air gap, and the ability to create an improved To realize heat dissipation or heat to be distributed locally (and thus less concentrated on one place).
Die Aufgabe wird durch die elektromagnetische Aktuatorvorrichtung mit den Merkmalen des Hauptanspruchs gelöst; vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.The object is achieved by the electromagnetic actuator device having the features of the main claim; advantageous developments of the invention are described in the subclaims.
In erfindungsgemäß vorteilhafter Weise ist es einerseits vorgesehen, bei lokal separiertem Anker von der Spuleneinheit (d.h. die Spuleneinheit umschließt nicht den Arbeitsluftspalt) der Spuleneinheit mindestens einen, bevorzugt mehrere Arbeitsluftspalt/e zuzuordnen, welche(r) entsprechend mit einer bzw. mehreren Ankereinheit(en) zusammenwirken. Insoweit kann der von der Spuleneinheit erzeugte Magnetfluss für die Mehrzahl der Ankereinheiten, entsprechend einer weiterbildungsgemäß zu beschreibenden Flussaufteilung, verwendet werden.In an advantageous manner according to the invention, it is provided, on the one hand, with locally separated armature of the coil unit (ie the coil unit does not surround the working air gap) of the coil unit to assign at least one, preferably several working air gap (s) corresponding to one or more armature unit (s) ) interact. In that regard, the magnetic flux generated by the coil unit for the plurality of anchor units, according to a flow distribution to be described further development, can be used.
So ist es im Rahmen der Erfindung bereits möglich, die Aufgabe auch durch eine gattungsgemäße elektromagnetische Aktuatorvorrichtung zu lösen, bei welcher lediglich eine (mindestens eine) Ankereinheit vorgesehen ist und, zum Verwirklichen des erfindungsgemäßen Prinzips, von der Spuleneinheit bzw. dem ersten Jochabschnitt seitlich beabstandet und/oder benachbart vorgesehen ist.Thus, within the scope of the invention, it is already possible to solve the problem by a generic electromagnetic actuator device in which only one (at least one) armature unit is provided and laterally spaced from the coil unit or the first yoke section for realizing the inventive principle and / or adjacent.
Gleichermaßen von der Erfindung umfasst ist das unabhängig beanspruchte Lösungsprinzip, dass die Spuleneinheit in Form einer Mehrzahl von voneinander getrennt, gleichwohl magnetflussmäßig miteinander verbundenen Einzelspulen realisiert ist, welche gemäß weiterer bevorzugter Ausgestaltungen der Erfindung dann lösungsgemäß eine lokal verteilte Anordnung jeweils (kleiner zu dimensionierender und damit auch potentiell geringer wärmeerzeugender) Einzelspulen ermöglichen, deren jeweiliger Magnetfluss dann kumuliert für den gemeinsamen Anker (bzw. den zugehörigen Arbeitsluftspalt) zusammengeführt und insoweit addiert wird.Equally encompassed by the invention is the independently claimed solution principle that the coil unit is realized in the form of a plurality of separate, yet magnetic flux interconnected individual coils, which according to further preferred embodiments of the invention then in solution a locally distributed arrangement each (smaller to be dimensioned and thus also potentially less heat-generating) individual coils allow their respective magnetic flux then cumulatively for the common anchor (or the associated working air gap) merged and added so far.
Allen Aspekten der Erfindung ist gemein, dass der Arbeitsluftspalt (bzw. der im Rahmen des ersten Erfindungsaspekts vorgesehene mindestens eine Luftspalt außerhalb des ersten Jochabschnitts gebildet ist/sind, mithin also nicht von einer (weiterbildungsgemäß typischerweise zylindrisch oder rechteckförmig ausgebildeten) Spuleneinheit umschlossen ist, sondern im vorstehend diskutierten Sinne lateral ausgelagert ist.It is common to all aspects of the invention that the working air gap (or the at least one air gap provided within the scope of the first aspect of the invention is / are formed outside the first yoke section, ie is not enclosed by a coil unit (typically cylindrical or rectangular in design) but instead is laterally outsourced in the sense discussed above.
In besonders bevorzugter Ausgestaltung des ersten Aspekts der Erfindung, nämlich der Ausbildung eines einzelnen oder einer Mehrzahl von magnetischen Flussleitkreisen in der Jocheinheit, wobei jeder der Flussleitkreise durch den (die gemeinsame Spule tragenden) ersten Jochabschnitt sowie über einen jeweiligen einer der Mehrzahl der Ankereinheiten zugeordneten Luftspalte verläuft, ist ein magnetischer Flusswiderstand von Flussleitmitteln mindestens eines der magnetischen Flussleitkreise in Abhängigkeit von einem darin fließenden magnetischen Fluss veränderlich. Dies geschieht insbesondere dadurch, dass durch geeignete Ausgestaltung eines wirksamen Flussleitquerschnittes dieser Flussleitmittel ab einer vorbestimmten magnetischen Flussdichte eine Sättigung auftritt, mithin ab dieser Schwelle der magnetische Flusswiderstand erhöht ist. Konsequenz dieses Effektes ist, dass dann ein Magnetfluss vom betreffenden Flussleitkreis in einen anderen der Flussleitkreise verdrängt wird, insoweit dann eine Ankerbewegung ausgelöst oder beeinflusst werden kann.In a particularly preferred embodiment of the first aspect of the invention, namely the formation of a single or a plurality of magnetic flux circuits in the yoke unit, wherein each of the flux circuits by the (common coil carrying) first yoke portion and via a respective one of the plurality of anchor units associated air gaps is a magnetic flux resistance of Flußleitmitteln of at least one of the magnetic flux control circuits in response to a flowing magnetic flux therein variable. This happens in particular in that saturation occurs as a result of suitable design of an effective flux-conducting cross-section of these flux-conducting means above a predetermined magnetic flux density, and therefore the magnetic flux resistance is increased from this threshold. The consequence of this effect is that a magnetic flux is then displaced from the relevant flux circuit into another of the flux circuits, insofar as an armature movement can then be triggered or influenced.
Weitere Möglichkeiten zur Voreinstellung bzw. vorbestimmten Beeinflussung des Bewegungsverhaltens der Mehrzahl der Ankereinheiten (in den jeweiligen Jochzweigen) besteht darin, die Luftspalte unterschiedlich auszugestalten (jeweils bezogen auf eine vorbestimmte, vergleichbare Ankerposition, etwa eine Anschlagposition der Ankereinheiten). Dabei ist es insbesondere weiterbildungsgemäß bevorzugt, den wirksamen Luftspalt in einem jeweiligen Jochzweig zu variieren bzw., entsprechend einem beabsichtigten Bewegungsverhalten (etwa einer beabsichtigten Reihenfolge einer Aktivierung), unterschiedlich einzurichten.Further possibilities for presetting or predetermined influencing of the movement behavior of the plurality of anchor units (in the respective yoke branches) is to design the air gaps differently (in each case based on a predetermined, comparable anchor position, for example a stop position of the anchor units). In this case, it is preferable, in particular according to the invention, to vary the effective air gap in a respective yoke branch or to set it up differently according to an intended movement behavior (for example, an intended sequence of activation).
Eine weitere Möglichkeit, das Schalt- bzw. Bewegungsverhalten einer jeweiligen Ankereinheit der Ankermittel zu beeinflussen, liegt darin, dieser Ankereinheit Federmittel oder dergleichen Kraftspeicher zuzuordnen und etwa weiterbildungsgemäß eine oder mehrere der Ankereinheiten gegen eine Rückstellkraft einer derartigen Feder zu lagern bzw. zu führen (wobei wiederum weiterbildungsgemäß durch unterschiedliche Ausgestaltungen etwa der Federkräfte dann das jeweilige Schalt- bzw. Bewegungsverhalten der zugeordneten Ankereinheiten vorbestimmt beeinflusst werden kann).Another way to influence the switching or movement behavior of a respective armature unit of the anchor means is to associate this armature spring means or the like power storage and about further education to store one or more of the armature units against a restoring force of such a spring or lead (where in turn further education by different configurations such as the spring forces then the respective switching or movement behavior of the associated anchor units can be influenced in a predetermined manner).
Die elektromagnetische Aktuatorvorrichtung gemäß dem zweiten Erfindungsaspekt, wonach eine Mehrzahl von Einzelspulen (in potentiell kleinem Bauraum) geeignet benachbart dem zweiten Jochabschnitt mit dem Arbeitsluftspalt so angeordnet sind, dass der Arbeitsluftspalt zwischen den Einzelspulen liegt, sieht weiterbildungsgemäß vorteilhaft vor, dass mindestens eine der Einzelspulen, weiter bevorzugt sämtliche der Einzelspulen, sich parallel zu einer Bewegungsrichtung der Ankereinheit erstrecken, sodass, etwa bei Anordnung der Einzelspulen um den Arbeitsluftspalt herum, hier eine besonders kompakte Einheit geschaffen werden kann, welche gleichwohl keine Symmetrie aufweisen muss.The electromagnetic actuator device according to the second aspect of the invention, according to which a plurality of individual coils (in potentially small installation space) suitably arranged adjacent to the second yoke section with the working air gap, so that the working air gap lies between the individual coils, advantageously provides that at least one of the individual coils, more preferably, all of the individual coils extend parallel to a direction of movement of the armature unit, so that, for example, when arranging the individual coils around the working air gap around, a particularly compact unit can be created, which nevertheless must have no symmetry.
Insbesondere ermöglicht es auch die vorliegende Erfindung durch die beschriebene Variabilität eine (bzw., bei mehreren Einzelspulen, mehrere) wirksame Querschnittsflächen des ersten Jochabschnitts zu optimieren, so dass etwa die darauf vorgesehene Spuleneinheit (im Hinblick z.B. auf das Kupfergewicht der Wicklung) optimiert werden kann.In particular, the present invention also makes it possible by the variability described to optimize one (or, in the case of several individual coils, several) effective cross-sectional areas of the first yoke section, so that, for example, the coil unit provided thereon (with regard, for example, to the copper weight of the winding) can be optimized ,
Durch weiterbildungsgemäß geeignet vorgesehene Flussleitmittel in Form von geeigneten Elementen (welche weiter bevorzugt etwa als herstellungstechnisch günstig zu stanzende Bleche bzw. Blechstapel realisiert sein können) lassen sich so einem jeweiligen Einsatzzweck (bzw. jeweiligem Einsatzort und den dort geltenden Einbaubedingungen) günstig angepasste Aufbaustrukturen realisieren: So ist es beispielsweise weiterbildungsgemäß bevorzugt, diese Flussleitelemente als flache bzw. plane Elemente zu realisieren, welche weiter vorteilhaft etwa beidseits von Mittelachsen sowohl der Mehrzahl der Spulenvorrichtungen, als auch des zweiten Jochabschnitts (mit dem Arbeitsluftspalt) zum flussleitenden Verbinden derselben vorgesehen sind, sodass wiederum eine einfach und großserientauglich fertigbare, gleichwohl im Hinblick auf eine Raumausnutzung optimierte Anordnung entsteht (wobei hier insbesondere auch konstruktive Möglichkeiten existieren, thermische Optimierungen vorzunehmen).By further education suitable provided Flußleitmittel in the form of suitable elements (which can be further preferably realized as production technology favorable punched sheets or metal stacks) can be as a specific purpose (or respective site and the applicable installation conditions) implemented low-priced construction structures: Thus, for example, according to further developments, it is preferable to realize these flux-conducting elements as flat or planar elements, which are furthermore advantageous approximately both sides of central axes of both the plurality of coil devices, as well as the second yoke portion (with the working air gap) are provided for flux-conducting connection thereof, so again a simple and mass production manufacturable, nevertheless optimized in terms of a space utilization arrangement arises (in particular also constructive There are possibilities to make thermal optimizations).
Damit ist es vorteilhaft und weiterbildungsgemäß insbesondere auch ermöglicht, unsymmetrische Anordnungen der Mehrzahl der Spuleneinheiten in Verbindung mit dem zweiten Jochabschnitt zu realisieren, wobei etwa zu diesem Zweck und bei einer Ausgestaltung der beschriebenen planen, plattenförmigen Flussleitmittel diese eine abgewinkelte (bzw. mit zueinander in einem Winkel etwa zwischen 90° und 180° in einer Ebene einer Flachseite zueinander stehenden Schenkeln realisierte) Struktur sein kann.Thus, it is advantageous and further development according to the invention in particular also allows to realize asymmetrical arrangements of the plurality of coil units in conjunction with the second yoke, for about this purpose and in an embodiment of the described flat plate-shaped flux guide these an angled (or with each other in a Angle approximately between 90 ° and 180 ° realized in a plane of a flat side to each other standing legs) structure can be.
Im Rahmen weiterer bevorzugter Realisierungsformen des zweiten Erfindungsaspekts ist es dabei auch möglich und bevorzugt, etwa die für den ersten Erfindungsaspekt (gemäß Hauptanspruch bzw. unabhängigen Anspruch 15) weiterbildungsgemäß vorgesehene Querschnittsbeeinflussung und/oder Flusswiderstandsbeeinflussung innerhalb eines jeweiligen Flussleitkreises geeignet analog vorzusehen, ebenso wie etwa die Ankermittel gegen eine geeignete Rückstellkraft anbietende Federmittel gelagert oder geführt sein können.Within the scope of further preferred embodiments of the second aspect of the invention, it is also possible and preferred to suitably provide analogously, for example, the cross-sectional influencing and / or flow resistance influencing provided within the respective flux circuit for the first aspect of the invention (according to main claim or independent claim 15), as well as, for example Anchoring means against a suitable restoring force offering spring means can be stored or guided.
Entsprechend analog ist es im Rahmen weiterer bevorzugter Ausführungsformen des ersten Erfindungsaspekts vorgesehen, die Jocheinheit mittels geeigneter blechförmiger, weiter bevorzugt durch Stanzen hergestellter Flussleitelemente, ggf. geeignet gestapelt, zu realisieren, um auch hier, neben Vorteilen in der Herstellung, Wirbelströme zu reduzieren.Analogously, it is provided within the scope of further preferred embodiments of the first aspect of the invention to realize the yoke unit by means of suitable sheet-shaped, more preferably stacked by flow punching, optionally suitably stacked to reduce eddy currents here, in addition to manufacturing advantages.
Auch gilt es als von der vorliegenden Erfindung erfasst und offenbart, dass etwa die mittels der planen bzw. flachen Flussleitmittel realisierte raumoptimierte (und weiterbildungsgemäß etwa abgewinkelte) Aufbaugeometrie analog auch für Realisierungsformen vorgesehen sein kann, bei welchen etwa endseitig der Flussleitmittel Ankereinheiten (mit einem jeweiligen Arbeitsluftspalt) geeignet vorgesehen sind, während in einem mittleren Bereich die gemeinsame Spuleneinheit vorgesehen ist.It is also considered to be encompassed and disclosed by the present invention that, for example, the space-optimized (and, for further training, approximately angled) space-saving geometry realized by means of the flat or flat flux-conducting means is also analogous can be provided for implementation forms, in which about the end of the flux guide anchor units (with a respective working air gap) are provided suitable, while in a central region, the common coil unit is provided.
Im Rahmen bevorzugter Weiterbildungen der Erfindung liegt es ferner, die Einzelspulen im Rahmen der Erfindung mit beliebigen Umfangskonturen bzw. Querschnitten zu versehen, um insoweit wiederum die baulich-konstruktiven Optimierungsmöglichkeiten zu nutzen; neben zylindrischen Außenkonturen ist es dabei insbesondere vorteilhaft und weiterbildungsgemäß beansprucht, eine oder mehrere der Einzelspulen querschnittlich rechteckig auszugestalten.In the context of preferred developments of the invention, it is further to provide the individual coils within the scope of the invention with any circumferential contours or cross-sections, in order to turn to use the constructional-constructive optimization possibilities; In addition to cylindrical outer contours, it is claimed in particular advantageous and weiterbildungsgemäß to design one or more of the individual coils cross-sectionally rectangular.
Im Ergebnis eignet sich die erfindungsgemäße elektromagnetische Aktuatorvorrichtung zwar bevorzugt zur Realisierung von Hydraulik- oder Pneumatikventillösungen, insbesondere im Fahrzeugbereich, ist jedoch nicht auf diese Anwendungsgebiete beschränkt. Vielmehr lässt sich die vorliegende Erfindung günstig für nahezu beliebige Anwendungsgebiete nutzen und geeignet konfigurieren, bei welchen bauliche bzw. räumliche Flexibilität in Verbindung mit flexibel gestaltbaren magnetischen Flussführungen bzw. Flussverläufen innerhalb der jeweiligen Flussleitkreise genutzt werden können.As a result, the electromagnetic actuator device according to the invention is indeed preferably for the realization of hydraulic or pneumatic valve solutions, especially in the vehicle sector, but is not limited to these applications. On the contrary, the present invention can be used favorably and suitably configured for virtually any field of application in which structural or spatial flexibility can be used in conjunction with flexibly configurable magnetic flux guides or flow paths within the respective flux guide circuits.

Die vorliegende Erfindung, unabhängig von den gezeigten oder weiteren möglichen Ausführungsformen, ermöglicht zahlreiche praktische Vorteile: So bietet etwa das Anordnen einer (oder mehrerer) Ankereinheit(en) in einer Verwendung als Ventil deutlich flexiblere Anschlussmöglichkeiten in der erfindungsgemäßen Konfiguration benachbart der Spuleneinheit (oder mehrerer Spuleneinheiten), etwa gegenüber dem bekannten Stand der Technik, bei welchem typischerweise die langgestreckte Ankereinheit von der Spuleneinheit (typischerweise zylindrisch-radial) umgeben ist. Entsprechend kann der Arbeitsluftspalt flexibler (und geeignet für einen jeweiligen Anwendungsfall) ausgestaltet werden.The present invention, regardless of the possible or other possible embodiments, offers numerous practical advantages: For example, arranging one (or more) armature unit (s) in a use as a valve offers significantly more flexible connection possibilities in the configuration according to the invention adjacent to the coil unit (s) Coil units), as compared to the known prior art, in which typically the elongated armature unit is surrounded by the coil unit (typically cylindrical-radial). Accordingly, the working air gap can be made more flexible (and suitable for a particular application).
Zusätzlich weiterbildungsgemäß vorteilhaft ist vorgesehen, angepasst an jeweilige Einbau- und Raumbedingungen, eine jeweilige Spule (bzw. die Mehrzahl von Einzelspulen) nicht mit zylindrischen Wicklungen zu versehen, sondern etwa rechteckige oder andere Spulenquerschnitte vorzusehen. Dies gilt insbesondere im Zusammenwirken mit flussleitenden Elementen, welche mithilfe von (typischerweise durch Stanzen hergestellten) Blechen realisiert sind und weiter vorteilhaft in geeigneten Stapelkonfigurationen vorliegen.In addition, according to further education advantageous is provided, adapted to respective installation and room conditions, not to provide a respective coil (or the plurality of individual coils) with cylindrical windings, but to provide approximately rectangular or other coil cross-sections. This is especially true in cooperation with flux-conducting elements, which are realized by means of (typically produced by punching) sheets and further advantageously present in suitable stacking configurations.
Damit lässt sich auch für die vorliegende Erfindung der Vorteil einer Wirbelstromreduktion (gerade für höhere Frequenzen) geblechter Flussleitelemente nutzen.This also makes it possible to use the advantage of an eddy-current reduction (especially for higher frequencies) of flat flux-conducting elements for the present invention.
