A shock absorber assembly includes a motion damping means that is filled with a fluid in operation and has a pair of relatively moveable parts ( 12, 14 ) and valve means ( 26 ) permitting flow of the fluid between the parts. The parts comprise a first part ( 12 ) and a second part ( 14 ) in which the first part is receivable whereby the parts are arranged for relative retracting and extending movement during which fluid is forced through the valve means ( 26 ) at respective predetermined controlled flow rates so as to dampen the movement. The relatively moveable parts contain respective primary chambers ( 24, 29 ) for the fluid. The first part is substantially smaller in cross-section than the second part to define an intermediate chamber ( 52 ) about the first part within the second part. Lateral port means ( 56 ) communicates the intermediate chamber ( 52 ) and the primary chamber ( 24 ) of first part ( 12 ). The flows at respective predetermined controlled flow rates are limited to respective flows (i) directly from the primary chamber ( 24 ) of the first part ( 12 ) to the primary chamber ( 29 ) of the second part ( 14 ) and (ii) via the intermediate chamber ( 52 ) and lateral port means ( 56 ) from the primary chamber ( 29 ) of the second part ( 14 ) to the primary chamber ( 24 ) of the first part ( 12 ).
