<p>In a remote controlled fluid piston-piston rod type damper (10), a ported damping piston (38) divides a cylinder (26) into upper and lower chambers (40, 42), a ''spoiler'' sleeve (96) reciprocably encircles an electrical coil (72), a pair of shoulders (54, 64) extend radially from the piston rod, and a pair of precompressed coil springs (44, 46) position the piston between the shoulders for reciprocable axial movement relative to the piston rod (36). An electrically controlled valve operates to regulate flow between the chambers in response to relative reciprocable motion between the piston rod (36) and the piston (38), the electrical coil being energized by an alternating voltage input whereby to generate a magnetic field about the sleeve. Movement of the spoiler sleeve through the magnetic field changes the current in the electrical due to self-inductance, and a remote control module (108) generates a control signal, in response to the change in coil current, to actuate the electrically controlled valve whereby to regulate flow between the chambers.</p> |
