that can rise and lower such as a parking deck structure the pressure signals also allow the level control system to act as a safety system to isolate a specific chamber upon significant decrease in pressure level by fully closing the associated chamber automated valve likewise the system can isolate all the cylinders or chambers 18 by closing their respective automatic chamber valves 24 upon any sudden decrease or low pressure indication from a supply discharge header pressure sensor 102 a plan view of a schematic of an alternative embodiment of the hydraulic power system 110 is shown in fig5 similar to the embodiment shown in fig2 the system 110 has a plurality of hydraulic chambers or cylinders 118 a reversible pump turbine generator 22 and a reservoir 26 in contrast to the first embodiment the system 110 has a plurality of distinct supply and discharge headers 122 and 124 each header 122 and 124 has a main valve 126 and a main automatic flow control valve 128 there is at least one header 122 or 124 for each side of the building structure 12 the hydraulic fluid 20 such as hydraulic oil fluid or water discharges from each of the hydraulic chambers or cylinders 118 through an automated chamber.
