Abstract

LA INVENCION SE REFIERE A UNA PERA HIDRAULICA (1) QUE INCLUYE UN EMBOLO PERCUTOR (3) QUE, MEDIANTE UN CONTROL (5), REALIZA ALTERNATIVAMENTE UN MOVIMIENTO DE ELEVACION Y UN RECORRIDO DE RETORNO. EL CONTROL, POR SU PARTE, ES ACCIONADO A TRAVES DE UNA VALVULA DE PRECONTROL (14) CON UNA POSICION DE RETORNO (17, 17A) QUE, EN FUNCION DE LA POSICION DEL EMBOLO PERCUTOR (3), SE SITUA EN UNA POSICION DE CIERRE O EN UNA POSICION DE APERTURA. LA INVENCION PROPONE DISEÑAR LA PERA (1) DE FORMA QUE AL SUPERAR UNA POSICION LIMITE DE ELEVACION DEL EMBOLO PERCUTOR (FLECHA 3E) LA VALVULA DE CONTROL (5) PASE A LA POSICION DE RETORNO. EN ESTA POSICION DE RETORNO Y MEDIANTE LA APLICACION DE PRESION A UNA CONDUCCION DE ELEVACION BREVE (18), LA VALVULA DE CONTROL (5) PASA PREMATURAMENTE A LA POSICION DE ELEVACION, REALIZANDO EL EMBOLO PERCUTOR (3) UNICAMENTE UNA ELEVACION BREVE. CUANDO LA HERRAMIENTA (4) QUE COOPERA CON EL EMBOLO PERCUTOR (3) PENETRA EN EL MATERIAL A PARTIR Y EL EMBOLO PERCUTOR SUPERA SU PLANO DETRABAJO NORMAL, SE REDUCE LA ENERGIA DE PERCUSION AL PRODUCIRSE UNA CONMUTACION AUTOMATICA DE LA ELEVACION.
