Tobul Bladder Accumulators

Tobul Bladder Accumulators

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.


Tobul Bladder-type Accumulators

The typical bladder-type accumulator is a bottom repairable design, in that the bladder is inserted into the shell through a bottom opening in the shell. This opening allows the installation of the oil port body/poppet valve assembly to seal the accumulator. Optional top repairable designs are available, along with various gas stem sizes (7/8" & 2”) if desired. Tobul’s parts and bladder kits are interchangeable with most major manufacturers.
