Hello Arnaud,

I have made two similar circuits with gas charged as well as spring loaded accumulators. All the parameters are same for both circuits. Please have a look at them on:

This is a zip file containing two circuits. I have included the dercription on the files too.
Looking forward for your comments on those results, Thanks

Yes, the discrepancy you observe with the gas-charged accumulator is because the block also accounts for some small structural deformation of the accumulator. The gas is not compressed until some fluid is pumped inside to compensate for this deformation. However, this is typically very small.
