Abstract

Se describe una disposicion hidráulica para regular un mecanismo elevador (12) de una máquina agrícola (10). La disposicion hidráulica (16) comprende un cilindro hidráulico (24) que tiene una cámara (50) capaz de ser accionada por presion, una válvula de flujo entrante ajustable proporcionalmente (22) que está conectada sobre el lado de salida por medio de una línea de flujo entrante (30) a la cámara (50) y que está conectada sobre el lado de entrada a una bomba hidráulica (18, 18'), una primera línea de salida (32) que hace conexion entre la cámara (50) y un tanque hidráulico (20), medios de ajuste (42, 44) para generar una senal de ajuste para el cilindro hidráulico (24), y una unidad de control electronico (40). Para proveer un sistema regulador que ahorre espacio que sea simple en términos estructurales, se propone disponer una válvula de alivio de presion electro-proporcional (26) en la primera línea de flujo saliente (32) y una válvula de no-retorno (28) que cierra en la direccion de la válvula de flujo entrante (22) dispuesta en la línea de flujo entrante (30), y también se proveen uno o más sensores conectados al cilindro hidráulico (24) y que generan una senal de sensor, siendo la válvula de alivio de presion (26) controlable o regulable en funcion de una o más senales de sensor y/o de la senal de ajuste.
