Accumulators increase efficiency and provide smooth operation in

Two designs of accumulators are widely used in hydraulic systems — piston and bladder accumulators, Figure 1. Piston accumulators include weight-loaded piston type, spring type, and hydropneumatic piston type. The weight-loaded type was the first used, but is very heavy for its capacity and much larger than modern piston and bladder types.
