Abstract

Perfeccionamientos en máquinas herramientas manuales, preferentemente martillo perforador o de percusión, con un mecanismo de percusión accionado especialmente por electromotor, en el que un percutor unido a través de un cojín de aire con un elemento de accionamiento que ejecuta un movimiento axiales vaivén, entrega su energía a una herramienta guiada en la máquina herramienta manual, caracterizados porque el elemento de accionamiento se apoya a través de un empujador, en una pista de leva cerrada en sí, rotativa.
