Abstract

A fluidic damping mechanism including a cylinder, a piston rod and a piston dividing the interior of the cylinder into a pair of working chambers is arranged to include within one of the working chambers a composite damping structure which imparts damping characteristics derived from the combined action of a mechanical spring mechanism and fluid throttling components.
