Bladder Type Accumulators


accumulator bladder type


The typical bladder accumulator makes use of the considerable differences in the relative compressibility between a gas and a fluid. 

 A typical design consists of a   gas proof elastomer membrane enclosed within a steel shell. The membrane contains compressed gas (normally dry nitrogen) and separates the gas from the hydraulic fluid. The compressed gas provides a pneumatic spring action to force stored hydraulic fluid from the accumulator into the system as needed.
