Consider two chambers A and B. B is connected to another chamber C through a valve. Chamber C is spring loaded. Meaning, as fluid flows into the chamber, it compresses a spring loaded piston (spring stiffness is very low). All chambers are pressurized. Now the requirement is when there is pressure fluctuation in chamber B, the valve remains closed. But when the pressure increases in A, the valve opens in such a way that the increase of pressure in A is equal to decrease of pressure in B. Is such a valve possible? Maybe a pressure controlling valve which takes pilot signal from A would work? The valve also needs to be bi-directional. Thanks
Whats the purpose of the valve? e.g To maintain a constant pressure in a heating system or hydraulic system? Maybe a diagram would be helpful for this? Are chambers A B and C connected to external inputs?
