Hydraulic Accumulators

The gas is entrapped in the cylinder and is compressed by the piston when the oil starts flowing into the accumulator. As the gas is compressed, its temperature and pressure rise. Equivalently, when the hydraulic system demands pressurized oil, the fluid leaves the accumulator and the gas expands, decreasing both its temperature and pressure.
