Abstract
Der für Kraftstoffinjektoren vorgesehene Aktor besitzt vorzugsweise einen gebauten Magnettopf mit einem eine ringförmige Magnetspule aufnehmenden Ringkanal, der am Spulenfenster von einem als Teil der Außenwand des Ringkanals angeordneten Ringteil nach radial einwärts bereichsweise überdeckt sein kann.The actuator provided for fuel injectors preferably has a built-in magnetic pot with an annular channel receiving an annular magnetic coil, which can be covered radially inwards in regions on the coil window by an annular part arranged as part of the outer wall of the annular channel.
Description
Technisches GebietTechnical area
Die Erfindung bezieht sich auf einen elektromagnetischen Aktor für Kraftstoffinjektoren mit einer elektrisch bestrombaren ringförmigen Magnetspule und einem die Spule in einem offenen Ringkanal aufnehmenden Magnettopf mit einem Innenpol radial innerhalb eines die offene Seite des Ringkanals bildenden Spulenfensters und einem Außenpol radial außerhalb des Spulenfensters, wobei Innen- und Außenpol bei elektrischer Bestromung der Magnetspule entgegengesetzte magnetische Polaritäten aufweisen.The invention relates to an electromagnetic actuator for fuel injectors with an electrically energizable annular magnet coil and a magnet cup receiving the coil in an open annular channel with an inner pole radially inside a coil window forming the open side of the annular channel and an outer pole radially outside the coil window. and external pole have opposite magnetic polarities when the electric current is supplied to the magnetic coil.
Stand der TechnikState of the art
Ein Kraftstoffinjektor mit einem derartigen elektromagnetischen Aktor wird in der
Für eine optimale Steuerung eines Verbrennungsmotors ist es von entscheidender Bedeutung, die Einspritzphasen exakt und reproduzierbar steuern zu können.For optimum control of an internal combustion engine, it is of crucial importance to be able to control the injection phases accurately and reproducibly.
Dabei ist es insbesondere erwünscht, auch kleinste Kraftstoffmengen mehrfach hintereinander einspritzen zu können.It is particularly desirable to be able to inject even the smallest amounts of fuel several times in a row.
Darstellung der ErfindungPresentation of the invention
Hier setzt die Erfindung an, indem angestrebt wird, einerseits sehr reaktionsschnelle Aktoren für die Steuerung der Kraftstoffinjektoren zu schaffen und andererseits durch ein geringes Bauvolumen der Aktoren entsprechend kleine Kraftstoffinjektoren zu ermöglichen.This is where the invention is based, on the one hand, on the one hand to create very fast-reacting actuators for the control of the fuel injectors and, on the other hand, to enable correspondingly small fuel injectors by means of a small construction volume of the actuators.
Dies wird durch Aktoren gemäß dem Anspruch 1 erreicht. Da das Spulenfenster gegenüber dem Boden des die Magnetspule aufnehmenden Ringkanals nach radial innen versetzt ist und dementsprechend gegenüber dem vorgenannten Boden einen verminderten mittleren Durchmesser aufweist, kann der Anker mit entsprechend vermindertem Durchmesser und dementsprechend mit geringerer Masse ausgebildet werden, so dass bei den Hubbewegungen des Ankers vermindernde Trägheitskräfte zu überwinden sind. Dadurch lässt sich eine beschleunigte Reaktion des Aktors erreichen.This is achieved by actuators according to
Durch eine gestufte Form des Ankers können Streuflüsse, die zu einer Reduktion der Magnetkraft führen würden, vermindert werden.By a stepped shape of the armature leakage fluxes that would lead to a reduction of the magnetic force can be reduced.
Um hinsichtlich der Ausgestaltung des Spulenfensters eine weitestgehende Freiheit zu erhalten, ist es vorteilhaft, gemäß einer bevorzugten Ausführungsform der Erfindung einen gebauten Magnettopf vorzusehen. Damit wird auch eine praktisch unbeschränkte Freiheit hinsichtlich der Form von Außen- und Innenpol geboten, so dass auch insofern eine Optimierung zur Erzielung hoher Stellkräfte ermöglicht wird.In order to obtain the greatest possible freedom with respect to the design of the coil window, it is advantageous, according to a preferred embodiment of the invention, to provide a built magnet cup. Thus, a virtually unlimited freedom in terms of the shape of the outer and inner pole is offered, so that in this respect an optimization to achieve high restoring forces is possible.
Im Übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche und die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der besonders bevorzugte Ausführungsformen der Erfindung näher beschrieben werden.Incidentally, with regard to preferred features of the invention, reference is made to the claims and the following explanation of the drawing, are described in detail with reference to the particularly preferred embodiments of the invention.
Schutz wird nicht nur für angegebene oder dargestellte Merkmalskombinationen, sondern auch für prinzipiell beliebige Kombinationen der angegebenen oder dargestellten Einzelmerkmale beansprucht.Protection is claimed not only for specified or illustrated feature combinations, but also for any combination of the specified or illustrated individual features.
