A B S T R A C T A FLUID-DAMPED PISTON & CYLINDER ASSEMBLY A fluid-damped piston and cylinder assembly comprises a cylinder within which a control piston mounted on a piston rod is movable to displace grease or other damping fluid through or past the control piston between a first chamber in front of the control piston and a second chamber behind the control piston and surrounding the piston rod. The increase in overall length of the first and second chambers as the length of the first chamber is reduced is taken up by a free piston whose displacement compresses a spring. The assembly can be used for generally supporting or for restricting or assisting the opening and closing of various lids and doors such as the boot lid or bonnet or tail-gate of a vehicle.
