Abstract

CURSOR DE CONTROL DE CARRERA PARA UTILES QUE TRABAJAN POR IMPACTO CON IMPULSION HIDRAULICA DEL TIPO DE MARTILLOS PERFORADORES. EL PISTON DE TRABAJO ESTA UNIDO A UNA BARRA DE CONTROL (33). AL DESPLAZARSE EL PISTON DE TRABAJO EL CONDUCTO DE LIQUIDO A PRESION DESPLAZA EL CURSOR DE CONTROL (35) CON LO QUE PERMITE EL DESALOJO DEL LIQUIDO A PRESION A TRAVES DE UN CANAL DE REFLUJO (48,47,45) PERMITIENDO EL REGRESO DE LA BARRA DE CONTROL (33) HASTA QUE LA RANURA DE CONTROL (52) UNE LAS RANURAS DE PASO (51,57), CERRANDO EL CANAL DE LIQUIDO A PRESION (58), CON LO QUE EL CURSOR VUELVE A SU POSICION INICIAL IMPULSADO POR DICHO LIQUIDO A TRAVES DEL ESPACIO DE TRABAJO.
