Title: MAGNETIC VISCOUS FLUID BUFFER
Abstract:
A buffer 100 is provided with a cylinder 10, a piston 20 slidably arranged within the cylinder 10 and a piston rod 21 connected to the piston 20. The piston 20 has a piston core 30 provided with a coil 33a on the periphery thereof, a flux ring 35 that surrounds the periphery of the piston core 30 and that forms a flow channel 22 between the piston core 30 and same and a temperature compensation unit 60 that advances and retreats with respect to the coil 33a due to expansion and contraction in accordance with temperature and that is provided, facing the coil 33a, on an inner circumferential surface 35c of the flux ring 35.
