Abstract

Perfeccionamientos en los dispositivos accionadotes de hélices de paso variable, caracterizados esencialmente porque sobre el buje (3) de la hélice, y en la parte central-terminal de ésta, se instala un racor rotativo (13) que permite la entrada y salida a su través de un fluido circulante a lo largo de dos conductos (12 y 12ª), que atraviesan longitudinalmente el racor (13), con entera libertad de rotación para el buje (3) de la hélice, sin afectar al eje motor (1) y quedando el conjunto totalmente exterior al codaste de la embarcación.
