Abstract

Un método en un aparato de taladrado, en el que la forma de impulso que transmite energía de impacto producida por un pistón (24) sobre la broca de taladro se ajusta casi a una forma de impulso mejor absorbida por el objeto (3) de taladrado desde la broca o un correspondiente vástago (1) de taladro mediante la conformación del impulso de energía que se mueve desde el pistón hasta el vástago (1) de taladro para que crezca en función del tiempo en un impulso de esfuerzo mediante el ajuste de la construcción de pistón para que crezca desde su superficie de impacto hacia atrás en cuanto a su diámetro (8a-d) o para que aumente en cuanto a sus concentraciones de masa, formado el pistón de percusión por al menos tres partes cilíndricas (9, 13, 14), teniendo dicho pistón caras de reborde entre dichas partes cilíndricas, caracterizado porque dichas caras de reborde o bridas correspondientes y el extremo trasero del pistón se presurizanmediante presión de funcionamiento con el fin de acelerar el pistón para percutir.
