Description
Die Erfindung betrifft eine Elektromagnetspule für Ventile und dergleichen mit einer Schaltung zur Temperaturkompensation, bestehend aus einem in der Stromzuführung angeordneten temperaturabhängigen Widerstand.The The invention relates to an electromagnetic coil for valves and the like with a circuit for temperature compensation, consisting of a in the power supply arranged temperature-dependent Resistance.
Bei modernen Kraftfahrzeugen werden häufig getaktete Elektromagnetspulen für Ventile und dergleichen eingesetzt, mit denen Druck- oder Durchsatzsteuerungen durchgeführt werden, z. B. bei elektrischen Druckwandlern zur Steuerung von Abgasrückführventilen.at modern motor vehicles are often clocked electromagnetic coils for valves and the like, with which pressure or flow controls carried out be, for. B. in electrical pressure transducers for controlling exhaust gas recirculation valves.
Diese Ventile sind überwiegend im Motorraum des Kraftfahrzeuges angeordnet und unterliegen den dort herrschenden Temperaturen, die im Bereich von –30°C bis +120°C liegen können.These Valves are predominant arranged in the engine compartment of the motor vehicle and subject to the prevailing temperatures, which are in the range of -30 ° C to + 120 ° C can.
Durch den temperaturabhängigen Widerstand des Spulendrahtes ist die Magnetkraft der Elektromagnetspule ebenfalls temperaturabhängig, d. h. diese verringert sich bei höheren Temperaturen.By the temperature-dependent Resistance of the coil wire is the magnetic force of the electromagnetic coil also temperature dependent, d. H. this decreases at higher Temperatures.

Es ist bekannt, dass bei temperaturabhängigen Widerständen die Widerstandsänderung nur angenähert linear zur Temperaturänderung erfolgt und darüber hinaus Exemplarstreuungen vorliegen.It is known that with temperature-dependent resistors resistance change only approximated linear to the temperature change done and above There are also copies scattered.
Aus diesem Grunde findet bei Elektromagnetspulen von elektronischen Steuerungen/Regelungen bereits eine temperaturabhängige Stromsteuerung Verwendung. Die dabei verwendeten Stromsteuerbauteile sind normalerweise in dem Steuergerät einer Zentralelektronik angeordnet und bilden in diesem Wärmequellen, die Maßnahmen zur Wärmeabführung erfordern. Darüber hinaus ist ein erheblicher Aufwand für die Temperaturerfassung an der Spule selbst notwendig.Out This reason finds in electromagnetic coils of electronic Controllers / regulations already a temperature-dependent current control Use. The current control components used are normally in the control unit arranged in a central electronics and form in this heat sources, the measures to dissipate heat. About that In addition, a considerable effort for the temperature detection is on the coil itself necessary.

Hiervon ausgehend stellt sich daher die Aufgabe, eine gattungsgemäße Elektromagnetspule derart auszubilden, daß bei vertretbarem Aufwand über einen größeren Temperaturbereich eine nahezu konstante Magnetkraft gegeben ist, wobei die herkömmliche Größe von Magnetspulen nicht überschritten werden soll.Of these, Starting therefore, the task arises, a generic electromagnetic coil such to train that at reasonable effort over a larger temperature range a nearly constant magnetic force is given, the conventional Size of magnetic coils not exceeded shall be.
Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst worden. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen angegeben.These The object is specified by the characterizing part of patent claim 1 Characteristics solved Service. Advantageous developments are specified by the subclaims.
