Abstract
Unos perfeccionamientos en las herramientas neumáticas de percusión, del tipo que comprende un cuerpo que tiene un orificio alargado con un extremo adaptado para recibir una parte de una herramienta en su interior, cuya herramienta se extiende al exterior de dicho cuerpo, un pistón desplazable alternativamente dentro de dicho orificio para suministrar impactos a la herramienta mencionada, un conjunto de pasos que tienen por lo menos una parte dentro de dicho cuerpo para permitir que el fluido hidráulico provoque el movimiento alternativo del mencionado pistón, disponiendo dicha parte de los pasos de fluido por lo menos una cámara situada lateralmente y hacia afuera de dicho orificio con una zona abierta en la superficie exterior de dicho cuerpo y asimismo una envolvente que tiene un orificio alargado en su interior.
