Abstract

L'invention concerne un ronfleur destiné à fonctionner avec une tension alternative. Dans ce ronfleur comportant un noyau magnétique 1, muni d'un enroulement d'aimant 2 et d'une armature battante 3 reliée à des ressorts 4, 5, on obtient un signal du ronfleur uniquement jusqu'à une intensité de courant indéterminée en utilisant un noyau 1 comportant, outre une partie 12 véhiculant un flux diamétre 2 , une partie 11 muni d'un enroulement 14 véhiculant un flux magnétique diamétre 2 déphasé par rapport au flux diamétre 1 , la grandeur diamétre 2 max.sin phiv étant accordée sur la valeur prédéterminée du courant et la force des ressorts étant inférieure à la force magnétique existant pour ce courant prédéterminé au minimum de la variation de la force magnétique. Application notamment aux cafetières électriques automatiques.
