Diaphragm Accumulator

A hydro-pneumatic accumulator is a device used specifically for storage of liquid under pressure.

Description

A hydro-pneumatic accumulator is a device used specifically for storage of liquid under pressure.
Since liquids, for all practical purposes, are incompressible, this is achieved by using the compressibility of gases.
A flexible rubber separator, i.e. a diaphragm, is inserted into the shell of the accumulator.
