Abstract

La presente invecnion se refiere a un disyuntor del tipo de autoinsuflacion, que comprende una cámara de compresion (18) formada por una pared de presion de un piston (11) semimovil, primeros medios para inmovilizar el piston durnate una primera parte del desplazamiento de apertura del conjunto de contacto movil, y segundos medios para desplazar axialmente el piston con el conjunto de contacto movil durante una segunda parte de este mismo desplazamiento. De acuerdo a la invencion, - el piston (11) incluye una parte de guía (11B) cilíndrica, solidaria de esta pared (11A), - los primeros medios comprenden un organo de tope (20) colocado entre el extremo de la parte de guía (11A) del piston (11), y una pieza de retencion (21) fija, siendo escamoteable o replegable este organo de tope (20), - los segundos medios comprenden un arreglo para replegar el organo de tope, actuando al final de la primera parte del desplazamiento.
