Abstract

Un aparato accionador magnético perfeccionado que comprende, en combinación: medios de núcleo magnético que tiene al menos un par de piezas polares; medios para producir flujo magnético unidireccional en dicha estructura de núcleo en dichas piezas polares que varía cíclicamente entre densidades de flujo alta y baja; medios de actuador de material permeable magnéticamente atraído a través de dichas piezas polares en una posición en la que está aprisionado por dicho flujo variable y que está cargado hacia una posición en la que está liberado; y medios accionables selectivamente cuando dicho flujo variable es menor que dicha alta densidad; para reducir todavía más dicho flujo magnético hasta un nivel que permita la liberación de dichos medios de actuador.
