Magneto-rheological accumulator for temperature compensation in hydropneumatic suspension systems
Hydro-pneumatic suspension systems consist of two fluids acting upon each other, usually gas over oil. In these systems, a compressible gas such as nitrogen is used as the springing medium, while a hydraulic f...
