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