Abstract
Perfeccionamientos en las máquinas de percusión, del tipo de las que comprenden una masa de choque constituida por un pistón de doble efecto animado con un movimiento alternativo que actúa sobre una herramienta que, encargada de transmitir la energía cinética contenida en la masa de choque en el momento del impacto hasta el punto donde esta energía ser utilizada por medio de una onda de choque, presenta un collarín destinado a apoyarse sobre un tope montado en el bastidor de la máquina, caracterizados porque este tope está constituido por una pieza tubular atravesada por lo menos parcialmente por la herramienta, y en un extremo de la cual ésta se apoya, estando dispuesta una cámara anular llena de un fluido incompresible bajo presión entre el otro extremo del tope y el bastidor de la máquina.
