  • Oil- and water-based continuous control valve
    Majdič, Franc ; Pezdirnik, Jože
    Environmental protection regulations are becoming increasingly strict. Using water instead of a hydraulic mineral or biodegradable oil in power-control hydraulic systems is a very positive step ... towards complying with these regulations. Since water hydraulics has many specifics, primarily related to lower viscosity and lubricity of water compared to oil, which greatly affects the leakage, and even more the friction and wear in these systems, a dedicatedtest rig is required for performing research with the real-scale components. The purpose of this paper is to present some preliminary representative results on dynamic responses of the two hydraulic circuits with and without a mass load.
