Title
(DE) VERSORGUNGSSCHALTUNG FÜR DEN BETRIEB EINES ELECKTROMAGNETISCHEN VERBRAUCHERS

Abstract
(DE)
Die Erfindung betrifft eine Versorgungsschaltung für den Betrieb eines elektromagnetischen Verbrauchers eines mit Generator (Lichtmaschine) sowie Batterie versehenen Fahrzeugs, insbesondere zum Betreiben mindestens eines Magnetventils einer Einspritzanlage einer Brennkraftmaschine des Fahrzeugs. Es wird eine Schaltungsanordnung vorgeschlagen, die den Verbraucher (6) für einen Aufbau seiner Erregung mit dem Generator (3) verbindet und anschließend für eine Aufrechterhaltung einer hinreichenden Erregung eine Verbindung zur Batterie (13) herstellt und die Verbindung zum Generator (3) unterbricht.
(EN)
The invention concerns a supply circuit for operating an electromagnetic consumer in a vehicle equipped with a generator (dynamo) and a battery, in particular for operating at least one solenoid valve in the vehicle engine fuel-injection system. Proposed is a circuit which connects the consumer (6) with the generator (3) to build up the supply of energy to the consumer and subsequently, in order to maintain a sufficient energy supply, establishes a connection with the battery (13) and disconnects the generator (3).
(FR)
L'invention se rapporte à un circuit d'alimentation pour la mise en ÷uvre d'un circuit consommateur électromagnétique d'un véhicule muni d'une génératrice (dynamo) ainsi que d'une batterie, en particulier pour l'actionnement d'au moins une électrovanne d'un système d'injection d'un moteur à combustion interne du véhicule. Il est proposé un circuit qui relie le consommateur (6) à la génératrice (3) en vue de l'établissement de son excitation et qui établit ensuite, en vue du maintien d'une excitation suffisante, un raccordement à la batterie (13) et qui interrompt le raccordement à la génératrice (3).
