Abstract

Un sistema hidráulico se adapta para recuperar potencial y energía cinética de una unión de trabajo de una máquina de trabajo. Un arreglo de válvulas puede configurar al sistema hidráulico en varios modos. El sistema hidráulico puede proporcionar suspensión y/o accionamiento para la unión de trabajo. La energía de la unión de trabajo puede mover a un vástago de un primer cilindro. El vástago puede presurizar fluido dentro del primer cilindro. El fluido presurizado puede fluir a partir del primer cilindro a través de una válvula y hacia un acumulador. El primer cilindro puede amplificar presión del fluido. El fluido presurizado en el acumulador puede accionar al primer cilindro. El movimiento del vástago del primer cilindro puede ocasionar accionamiento simultáneo de un segundo cilindro. Un controlador puede monitorizar presiones y posiciones de componentes del sistema hidráulico y controlar al arreglo de válvulas.
