5 Hydraulic Components Accumulator Types Spring Loaded Gas Charged (Nitrogen) Weight Loaded Hydraulic Counter Loaded

6 Accumulator Types Spring Loaded Types Sealed Piston Piston may be sealed with an O-ring, quad ring, or square ring and may even be backed up with a Teflon cushion washer depending on pressure requirements of system and spring strength

7 Accumulator Types Spring Loaded Types Sealed Piston Compound Spring This accumulator system is often used for variable loads or independent pressure volumes for light load extensions in sequential operation

8 Accumulator Types Spring Loaded Types Sealed Piston Compound Spring Diaphragm The sprung side may be pneumatically boosted

9 Accumulator Types Spring Loaded Types Sealed Piston Compound Spring Diaphragm Hydraulic Counter Loaded Notice: 2 different size pistons allowing for mechanical advantage boosting that are balanced by 2 springs working against each other (learn the math!!)
