Abstract

Mejoras en los sistemas de barras de regulación para generadores de energía, caracterizadas porque el sistema comprende medios de accionamiento, medios de guía, un conjunto de combustible y una barra de regulación, estando adaptada la barra para movimiento alternativo en los medios de guía y comprendiendo el conjunto de combustible un árbol dispuesto en alineación axial con la barra y acoplado con susceptibilidad de liberación por un extremo de la misma, estando acoplado el árbol con susceptibilidad de liberación por su otro extremo a los medios de accionamiento, y medios que bloquean el árbol contra rotación con respecto a la barra de regulación con susceptibilidad de liberación.
