Name TWO functions of hydraulic accumulators.

Here are two functions of hydraulic accumulators:

1. Energy Storage: Hydraulic accumulators store hydraulic energy, typically in the form of pressurized fluid, which can be released to supplement pump flow during peak demands or provide emergency power.
2. Shock Absorption/Pulsation Dampening: They absorb pressure shocks and dampen pulsations caused by pumps or sudden valve closures, leading to smoother system operation and reduced wear on components.
