51 penetrating an axial length of the piston rod 9 the supply wires 6 thereby connect to the internal piston electromagnet 13 with reference to fig6 the flow of mrf through regulating orifice 14 is affected or controlled by the external electromagnet 2 this is accomplished by altering mrf apparent viscosity with flow regulation ring 22 the flow regulation orifice 14 and the associated viscosity flow regulation ring 22 thereby cooperatively restrict mrf flow between the damper chamber 16 and the liquid spring chamber 17 alternatively flow regulation orifice 14 can be physically blocked or eliminated to prevent flow between the damper chamber 16 and the liquid spring chamber 17 in this configuration mrf can be used in the damper chamber 16 and separate compressible mrf or other compressible gas or compressible fluid such as compressible silicone fluid or fluid containing compressible elastomers can be used in the liquid spring chamber 17 as noted above the internal accumulator set screw 7 passes through the lower rod end 21 the set screw 7 is attached to the internal accumulator assembly not shown in fig6 with reference to fig7 the internal accumulator set screw 7 passes through the lower rod end 21 and is attached to the accumulator spring compression nut 23 which adjusts and thereby controls the preset force of the accumulator spring 24 the floating accumulator piston 25 is otherwise relatively freely moveable between upper and lower stops 56 57 adjacent the lower rod end 21 the lower rod end 53 may thus displace or increase or decrease mechanical spring force biasing fluid in the liquid spring chamber 17 providing an adjustable energy.
