Abstract

DISTRIBUIDOR PARA CILINDROS HIDRAULICOS, ESPECIALMENTE APLICABLE A CILINDROS DE ACCIONAMIENTO DE GRUAS, QUE COMPRENDE UNA CORREDERA AXIALMENTE DESLIZABLE, PARA SELECCIONAR EL CIRCUITO DEL ACEITE.LA CORREDERA ES HUECA Y DEFINE DOS CAMARAS INDEPENDIENTES, ADYACENTES A LOS CONDUCTOS DE SUMINISTRO Y RETORNO DE LAS CAMARAS DEL CILINDRO, CON LOS QUE SE COMUNICA A TRAVES DE TALADROS FORMADOS EN LA PARED DE LA CORREDERA. UNA DE LAS CAMARAS INCLUYE MEDIOS PARA VARIAR LA SECCION DE PASO DE LOS TALADROS EN FUNCION DE LA PRESION DEL ACEITE DE RETORNO PROCEDENTE DE LA CAMARA DE RETROCESO DEL CILINDRO. LA OTRA CAMARA INCLUYE MEDIOS PARA ABRIR O CERRAR LA INTERCOMUNICACION A TRAVES DE DICHA CAMARA, EN FUNCION DE LA PRESION DEL ACEITE QUE LLEGA PROCEDENTE LA BOMBA, AL CONDUCTO DE SUMINISTRO DE ACEITE A LA CAMARA DE RETROCESO DEL CILINDRO. SE LOGRA REGULAR EL CAUDAL COMO FUNCION INVERSA DE LA CARGA Y REDUCIR EL EFECTODE LA PRESION INDUCIDA.
