Abstract
EN UN MANDO HIDRAULICO DE CORREDERA PARA CILINDROS DE TRABAJO CON DISTINTAS VELOCIDADES DEL EMBOLO, EN EL QUE EL VOLUMEN DEL MEDIO DEL FLUIDO HIDRAULICO QUE ACCIONA EL EMBOLO ESTA AJUSTADO A LA CORRESPONDIENTE VELOCIDAD DEL EMBOLO, Y LA DIRECCION DEL MOVIMIENTO DEL EMBOLO ES REGULADA CON UNA VALVULA DE PASO CONTROLADA, SE HA PREVISTO SEGUN LA INVENCION QUE LA VALVULA DE INVERSION (S3) SE CONTROLE HIDRAULICAMENTE CON UNA VALVULA PILOTO (A), LA CUAL ES AJUSTABLE CON LOS IMPULSOS DE CONTROL PARA EL CILINDRO DE TRABAJO (1), Y QUE SE MONTE ENTRE LOS TRAMOS PILOTO (11, 12), DESDE LA VALVULA PILOTO (A) A LA VALVULA DE INVERSION (S3), UNA VALVULA DE CONTROL HIDRAULICAMENTE PRECONTROLADA, EN EL QUE POR UNA DE LAS DOS CIRCULA EL VOLUMEN DEL MEDIO DEL FLUIDO HIDRAULICO, POR LO QUE A CADA POSICION DE LA VALVULA DE MANIOBRA (B), SE LE HA ASIGNADO UNA VELOCIDAD DEL EMBOLO.
