has it been designed? high pressure hydraulic fluid reservoir.
(OP)
the reservoir that i picture is small in volume (.200 litre) but will hold a 'non-compressible' fluid at a given pressure( 25000-30000 psi)
would it be possible to use gas as a spring to place a force on teh fluid when the fluid pump is not creating pressure. in order to reduce the pressure spikes or a gear pump. and also to aid in the reduction of pressure loss when there is a large increase in the amount of fluid being used up. also conversely reduce the pressure spike when a large decrease in fluid is called for.

Haskel should be able to advise. The gas is usually Dry Nitrogen.

Normal set up for an accumulator is to have a rubber lung in the casing. The lung is charged with Nitrogen via A Schafer valve and there is no physical contact between the gas and the hydraulic fluid.
