How Hydraulic Accumulators Work

(Piston, Bladder, Diaphragm / Gas-Charged Types)

A hydraulic accumulator is a pressure vessel that plays multiple essential roles in a hydraulic system. It maintains system pressure, stores and recovers energy, reduces pressure peaks, supports chassis suspension systems, and dampens shock, vibration, and pulsations.

Operating Principle

Under pre-charged gas pressure (typically nitrogen), the accumulator stores a volume of hydraulic fluid that can be released back into the system when needed.

•  When system pressure rises, fluid enters the accumulator and compresses the gas.

•  When system pressure drops, the compressed gas expands and forces the stored fluid back into the hydraulic circuit.

This simple yet effective energy-storage mechanism allows the accumulator to respond almost instantly to changing demand.

Key Advantages

•  Improved energy efficiency

•  High operating reliability and long service life

•  Extremely fast response in hydraulic circuits

•  Complete range of accumulator types available from a single source

•  Application-optimized designs featuring in-house developed seals and diaphragms

•  Independent component manufacturer with specialized expertise
