Abstract

SE PROPONE UN CONTROL DE LA VELOCIDAD DE FORMA INDEPENDIENTE DE LA PRESION DE CARGA DE ELEMENTOS DE AJUSTE HIDRAULICOS EN CARGAS ACORDADAS DE ANTEMANO, EN PARTICULAR EN MAQUINAS DE CONSTRUCCION, CON AL MENOS UNA BOMBA, AL MENOS UN CURSOR DE CONTROL ASI COMO AL MENOS UNA BALANZA DE PRESION. LA BALANZA DE PRESION O SE ENCUENTRA EN LA CONDUCCION DE LA UNION DEL ESPACIO CONTROLADO MEDIANTE VACIO DEL ELEMENTOS DE CONTROL CONFIGURADO COMO CILINDRO HIDRAULICO PARA EL CURSOR DE CONTROL, O SE UTILIZA SIN EMBARGO EN LA CONDUCCION ENTRE LA SALIDA DEL CURSOR DE CONTROL Y EL TANQUE. LA ZONA DE RETORNO DEL EMBOLO DE CONTROL PERTENECIENTE ESTA CONFIGURADA COMO DIAFRAGMA DE PRESION DIFERENCIAL. LA INDICACION DE PRESION ANTES DE QUE LA CORRIENTE DE ACEITE PASE A TRAVES DEL DIAFRAGMA DE PRESION DIFERENCIAL EN LA BALANZA DE PRESION ES CONDUCIBLE A TRAVES DE UNA CONDUCCION SOBRE LA CARA DE LA BALANZA DE PRESION DIRIGIDA A LA CAMARA ELASTICA.
