Abstract
A pseudo-linear hydro-pneumatic isolation spring includes a cylinder having an interior partially filled with a hydraulic fluid as well as a piston assembly that is movably disposed within the cylinder including a piston head and a piston rod. A plurality of accumulators are fluidically connected to the interior of the cylinder in parallel, each of the accumulators being charged to a different pressure and size so as to actively engage the cylinder only after a threshold pressure force based on fluid displacement of the piston in the cylinder has been reached.
