Which accumulator type is also used as a fluid intensifier?

A differential-piston accumulator is designed to act both as an energy storage device and as a fluid intensifier. This unique configuration features two pistons of different diameters. When hydraulic fluid is introduced, it exerts pressure on the larger piston, which translates to an increased pressure on the smaller piston. This amplifies the force of the fluid, allowing it to operate at higher pressures, effectively intensifying it.

The ability of a differential-piston accumulator to convert low-pressure hydraulic fluid into high-pressure makes it particularly valuable in applications where higher fluid intensity is required without needing a separate intensification system. Other accumulator types, such as piston or bladder accumulators, serve primarily for the storage of hydraulic energy and do not inherently offer the same fluid intensification capability. This characteristic sets the differential-piston accumulator apart in hydraulic systems needing both energy storage and pressure boosting functions.
