Abstract

Los cilindros de actuacion doble sobre las estructuras elevadoras de rueda de un implemento agricola estan conectadas en paralelo e incluyen la estructura de valvula de verificacion operada conectada a los extremos de base de los cilindros para mantener el cronometraje de la estructura de rueda elevadora aun bajo cargas diferenciales grandes sin un eje oscilador u otro dispositivo de cronometraje mecanico que se extienda entre las estructuras de rueda. La estructura de valvula de verificacion evita una retraccion de cilindro indeseada y proporciona un cierre de cilindro para el transporte sin la necesidad de valvulas adicionales. Cuando la presion es aplicada a los extremos de varilla de los cilindros, la estructura de valvula de verificacion permite al fluido el fluir desde los extremos de base. Los orificios son insertados en los extremos de base de los cilindros 86 para proporcionar una presion de descanso optimo para las valvulas de verificacion.
