Abstract

SE PRESENTA UN TALADRO DE ROCAS CON UN MECANISMO DE PERCUSION QUE INCLUYE UN PISTON (32), UN CUERPO (12) EN EL CUAL SE FORMA UNA CAMARA (14), AL MENOS UN PRIMER CILINDRO (18) QUE SE SITUA EN LA CAMARA Y QUE, SOBRE UN LADO INTERIOR, FORMA AL MENOS PARTES DE UN MANGUITO PARA EL PISTON (32), Y UNA VALVULA (22), PARA CONTROLAR EL MOVIMIENTO DEL PISTON, QUE SE SITUA SOBRE UN LADO EXTERNO DEL PRIMER CILINDRO (18). UN MEDIO DE DETENCION (142) INTEGRALMENTE UNIDO AL PRIMER CILINDRO EVITA QUE LA VALVULA PUEDA SEPARARSE.
