Abstract

L'invention se rapporte aux dispositifs permettant d'ouvrir et de fermer une canalisation dans laquelle circule un fluide, au moyen d'un circuit électrique de commande. L'électrovanne selon l'invention comprend une bobine, à laquelle peut être appliqué un courant de commande qui y crée un champ magnétique, une pièce mobile dont une partie est magnétique pouvant occuper deux positions assurant l'ouverture et la fermeture de la canalisation. Elle se caractérise par le fait que les deux positions sont stables, la première grâce au fait que la partie magnétique est un aimant permanent, ce qui permet le maintien de la partie mobile à l'intérieur de la bobine en l'absence de champ magnétique, la deuxième grâce au propre poids de la pièce mobile. Le passage d'une position à l'autre s'effectue par deux impulsions de courant de polarités opposées. L'invention s'applique notamment aux armoires réfrigérantes comportant deux compartiments que l'on désire porter à des températures différentes.The invention relates to devices for opening and closing a pipe in which a fluid circulates, by means of an electric control circuit. The solenoid valve according to the invention comprises a coil, to which can be applied a control current which creates a magnetic field therein, a moving part, part of which is magnetic, which can occupy two positions ensuring the opening and closing of the pipe. It is characterized by the fact that the two positions are stable, the first thanks to the fact that the magnetic part is a permanent magnet, which allows the maintenance of the moving part inside the coil in the absence of a magnetic field. , the second thanks to the own weight of the moving part. The passage from one position to another is effected by two current pulses of opposite polarities. The invention applies in particular to refrigerated cabinets comprising two compartments which it is desired to bring to different temperatures.
