  • Energy efficiency in hydraulic systems
    Publication number: 20070197410
    Abstract: The present invention describes use of a fluid having a VI of at least 130 to improve the energy efficiency of a hydraulic system. Furthermore, the present invention relates to a hydraulic system comprising a hydraulic fluid having a VI of at least 130, a unit for creating mechanical power, a unit that converts mechanical power into hydraulic energy, and a unit that converts hydraulic energy into mechanical work. Preferentially, engine speed can be reduced to decrease load and stress while delivering the same amount of hydraulic power.
