Abstract

A suspension unit or suspension system includes an accumulator (112) for storing fluid under gas pressure and a motion damping unit (114) for storing fluid under pressure in fluid communication with each other. A valve arrangement (126) is located intermediate the accumulator (112) and the motion damping unit (114) to allow fluid under pressure to flow between the accumulator (112) and motion damping means (114). A piston (122) reactive to movement of the accumulator (112) and motion damping unit (114) with respect to each other is used to control the movement and fluid through the valve (126) so as to adjust the relative positions of the accumulator (112) and the motion damping unit (114). In one embodiment, the accumulator (112) is separate to the motion damping unit (114) and is connected thereto by a flexible hose or other conduit, whereas in another embodiment the accumulator (112) and motion damping unit (114) are a single unit in fluid communication with each other through the valve arrangement (126).
