Epoll - Piston Accumulators

The piston hydro pneumatic accumulator, is a component used to exchange energy using the hydraulic system to which it is connected. It escapes energy at determined moments, the accumulate in the form of pressure energy of gas, it readily and integrally replenishes the system on demand, returning to the conditions of receiving again.

The piston accumulator is particularly constructed with two chambers, one of which is filled with gas at opportune
pressure, and the second one connected to the hydraulic circuit. The gas pressure must be chosen in relation to the conditions of work of the accumulator, and constitutes the pre-loading pressure.
