Abstract:
(EN) The invention relates to a method for switching a current (I) in an electromagnet (18) of a switchable solenoid valve (15). The current (I) is switched on in successive switching cycles (33) in order to close the valve (15) against the force of a spring (28), thus generating the current (I) by electrically connecting the electromagnet (18) to a voltage source (U). According to the invention, the current (I) in the electromagnet (18) is generated with a current direction opposite the respective previous switch cycle (33) in at least two successive switch cycles (33) in a switched operation (Q) of the valve (15) .
(FR) L'invention concerne un procédé pour commuter un courant (I) dans un électroaimant (18) d’une électrovanne (15) commutable, le courant (I) étant commuté dans chaque cas dans une succession de cycles de commutation (33), de manière à fermer l’électrovanne (15) à l’encontre d’une force exercée par un ressort (28) et le courant (I) étant alors produit par connexion électrique de l’électroaimant (18) avec une source de tension (U). Selon l'invention, dans un mode de fonctionnement de remplacement (Q) de l’électrovanne (15), lors d’au moins deux cycles de commutation (33) successifs, le courant (I) est produit dans l’électroaimant (18) dans la direction inverse de courant comparativement au cycle de commutation précédent.
(DE) Die Erfindung betrifft ein Verfahren zum Schalten eines Stromes (I) in einem Elektromagneten (18) eines schaltbaren Magnet-Ventils (15), wobei in aufeinander folgenden Schaltzyklen (33) jeweils der Strom (I) eingeschaltet wird, um das Ventil (15) gegen eine Kraft einer Feder (28) zu schließen, und hierbei der Strom (I) durch elektrisches Verbinden des Elektromagneten (18) mit einer Spannungsquelle (U) erzeugt wird. Die Erfindung sieht vor, dass in einem Tauschbetrieb (Q) des Ventils (15) bei zumindest zwei aufeinanderfolgenden Schaltzyklen (33) der Strom (I) in dem Elektromagneten (18) im Vergleich zum jeweils vorangegangenen Schaltzyklus (33) mit umgekehrter Stromrichtung erzeugt wird.
