In a system having many unequal-area dampers (16) and a common main accumulator (34) for providing positive hydraulic pressure thereto, a shutoff valve (64) and a backup accumulator (62) are provided for each damper (16). In the event of a loss of pressure in the system, the shutoff valve (64) isolates each damper (16) and associated backup accumulator (62) from the rest of the system so that positive hydraulic pressure is provided to each associated damper (16).

A method of providing a backup mode of operation for a hydraulic system including unequal piston-area dampers and a common main accumulator for providing positive pressure thereto, comprising: interposing a shutoff valve between each damper and the main accumulator; and connecting a backup accumulator to each damper on the damper side of the associated shutoff valve for providing a positive pressure thereto in the backup mode; wherein the shutoff valves are open to permit fluid communication between the main accumulator and the dampers during normal operation, and are closed to prohibit fluid communication between the main accumulator and the dampers in the backup mode of operation.
