An reusable impact energy absorbing device utilized a liquid filled piston and cylinder assembly whereby upon application of an impact to the piston the piston will move along the length of the cylinder and discharge the liquid outwardly through a sequence of valves into an elastic balloon structure secured to the piston and cylinder assembly to capture the fluid. The valves may be two-way valves which will allow the return of the fluid from the elastic balloon to the cylinder due to the creation of a partial vacuum in the cylinder upon upward movement of the piston when the impact force is removed. Upon discharge of the fluid from the cylinder through each valve, the fluid is forced to travel through a restricted labyrinth to further dissipate the impact energy.
