Abstract
UN CONJUNTO DE LA VALVULA DE UN MOTOR (10) DISPUESTO DENTRO DE UN TREN DE VALVULAS ELECTROHIDRAULICO SIN LEVAS QUE COOPERA CON UN SISTEMA HIDRAULICO (8) QUE TIENE UNA DIVISION DE BAJA PRESION (70) Y UNA DIVISION DE ALTA PRESION (68) PARA ABRIR Y CERRAR SELECTIVAMENTE LA VALVULA DEL MOTOR (12). LA VALVULA DEL MOTOR (12) ESTA FIJADA A UN PISTON DE LA VALVULA (16) QUE HAY DENTRO DE UNA CAMARA DE PISTON (18). UN VOLUMEN (42) POR DEBAJO DEL PISTON (16) QUEDA CONECTADO A LA DIVISION DE ALTA PRESION (68) Y UN VOLUMEN (20) POR ENCIMA DEL PISTON (16) QUEDA CONECTADO SELECTIVAMENTE A LA DIVISION DE ALTA PRESION (68) O A LA DIVISION DE BAJA PRESION (70) A TRAVES DE UNA VALVULA ROTATIVA (34), PARA ABRIR Y CERRAR LA VALVULA DEL MOTOR. UN MOTOR (60) HACE QUE LA VALVULA ROTATIVA (34) ROTE.
