Abstract
LA INVENCION SE REFIERE A UN MARTILLO DE PERCUSION HIDRAULICO QUE CONSTA DE UN PISTON (1), UN ACUMULADOR DE PRESION (7) EN EL CIRCUITO DE ALTA PRESION, UNA VALVULA PRINCIPAL (8) QUE DIRIGE ALTERNATIVAMENTE UNA PRESION ALTA Y BAJA A AL MENOS UNA DE LAS SUPERFICIES DE PRESION (2,4) DEL PISTON (1) PARA HACER QUE EL PISTON (1) OSCILE Y UNA HERRAMIENTA (3) QUE GOLPEA EL PISTON Y, PARA CONTROLAR LA VALVULA PRINCIPAL (8), UNA VALVULA DE PRESION DE CONTROL (9) QUE SE ABRE CUANDO LA PRESION SOBREPASA UN VALOR PREDETERMINADO. SEGUN LA INVENCION, LA VALVULA DE PRESION DE CONTROL (9) SE ENCUENTRA COLOCADA DE TAL MODO QUE EL HUSILLO (27) DE LA VALVULA DE PRESION DE CONTROL (9) QUEDE CONECTADO POR UN EXTREMO AL CIRCUITO DE ALTA PRESION DEL MARTILLO DE PERCUSION HIDRAULICO. ADEMAS, PARA PODER AJUSTAR LA PRESION OPERATIVA MAXIMA Y MINIMA DEL MARTILLO DE PERCUSION HIDRAULICO, EL OTRO EXTREMO DEL HUSILLO (27) DE LA VALVULA DE PRESION DE CONTROL (9) INCLUYE UN ESPACIO DE CONTROL (20) CONECTADO A TRAVES DE LOSCONDUCTOS HIDRAULICOS A AL MENOS DOS DISPOSITIVOS DE CONTROL DE LA PRESION (30,31,32,33) QUE HAY CONECTADOS HIDRAULICAMENTE EN PARALELO O EN SERIE.
