Abstract

Aparato de mecanización por chispas, del tipo que tiene medios capacitores de almacenamiento de energía que se cargan desde una fuente de suministro de energía en corriente continua a través de un circuito de carga, y se descargan a través de un interruptor de cierre periódico a través del intervalo disruptivo ionizable definido entre electrodos de descarga tales como, preferiblemente, un electrodo-herramienta y una pieza conductiva a trabajar; caracterizado por medios de retardo para detener automáticamente la aplicación de la tensión de la fuente de suministro de energía al condensador durante un intervalo de retardo predeterminado consecutivo a la iniciación de cada descarga del condensador, para permitir que el circuito de descarga llegue a desionizarse antes de volver a ser aplicada a los medios de almacenamiento de energía la tensión de alimentación.
