Abstract
SE DESCRIBE UN DISPOSITIVO DE CONTROL HIDRAULICO PARA UN SISTEMA DE CARGA OSCILANTE. ESTE SISTEMA CONSTA DE UN HIDROUTILITARIO (V) DOBLE QUE SE PUEDE IMPULSAR, EL CUAL ESTA UNIDO A UNA FUENTE DE PRESION (P) O A UNA VUELTA (T) MEDIANTE DOS CONDUCTORES DE TRABAJO SEPARABLES (9, 10), Y MEDIANTE UNA VALVULA DE CONTROL (C) A ELEGIR. CONSTA DE AL MENOS UNA VALVULA QUE MANTIENE LA CARGA (H) CONTROLABLE MEDIANTE UN CONDUCTOR DE PRESION DE CONTROL (16) DE LOS OTROS CONDUCTORES DE TRABAJO (9) Y COLOCADA EN EL CONDUCTOR DE TRABAJO (10) ENTRE LA VALVULA DE CONTROL (10) Y EL HIDROUTILITARIO (V). SE CONECTA UN DISPOSITIVO DE AMORTIGUACION (X) QUE CONSTA DE UN PASO DE REGULACION DE DISTURBIOS (D2) EN EL CONDUCTOR DE LA PRESION DE CONTROL (16) DE LA VALVULA QUE SOPORTA LA CARGA (H) QUE SALE DEL CANAL DE PASO (23). EN EL CONDUCTOR DE PRESION DE CONTROL (16) HAY UN PASO DE ESTRANGULAMIENTO DE UNO, EL CUAL ES MAS PEQUEÑO QUE EL PASO DE REGULACION DE DISTURBIOS (D2).
