Abstract
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).
