Abstract

EL MECANISMO EXPLOTA LA ENERGIA DE REBOTE DE LA GRAN MASA, QUE DEPENDE DE LA DUREZA DEL MATERIAL EN QUE OPERA LA HERRAMIENTA. SE BASA EN EL FUNCIONAMIENTO DEL MECANISMO COMO EN LA PATENTE EUROPEA NO. 0085279, Y EN PROPORCIONAR MEDIOS ADECUADOS PARA VARIAR EL GOLPE DEL DISTRIBUIDOR DURANTE LA FASE DE MOVIMIENTO HACIA ARRIBA DEL PISTON, PARA ANTICIPAR O POSTPONER LA FASE DE PERCUSION CUANDO LA HERRAMIENTA OPERA RESPECTIVAMENTE EN UN MATERIAL MENOS O MAS DURO. EN ESTE PRIMER CASO, LA ANTICIPACION DEL GOLPE DE PERCUSION CAUSA UNA DISMINUCION DEL VOLUMEN DE LA CAMARA CILINDRICA DONDE TRABAJA EL ACEITE A PRESION Y POR LO TANTO, BAJO LA MISMA POTENCIA, CAUSA UN AUMENTO EN LA FRECUENCIA DE LOS GOLPES, SI EL FLUJO DEL ACEITE QUE TRABAJA SIGUE INALTERADO.
