An accumulator with bladder, also known as a bladder-type accumulator, is a compressed storage device used in hydraulic and pneumatic systems. It consists of a cylindrical housing, which contains a flexible bladder made of elastic material such as rubber or synthetic polymers. The bladder divides the housing into two compartments. One compartment is filled with hydraulic fluid or compressed gas, while the other compartment remains empty.
The operation of an accumulator with bladder is based on the principle of displacement. When hydraulic fluid or compressed gas enters the accumulator, the bladder inside compresses, thereby reducing the volume of the fluid or gas. This compression of the bladder creates a temporary storage of energy, which can be used to supply additional power to the system when needed.
Accumulators with bladder are commonly used in applications where there is a need for energy storage and pressure stabilization. They can be found in various industries, including automotive, aerospace, manufacturing, and energy sectors.

An accumulator with bladder, also known as a bladder-type accumulator, is a storage device used in compressed hydraulic and pneumatic systems to store energy in the form of fluid under pressure. It consists of a strong cylindrical shell, typically made of steel, and a flexible bladder that separates the gas and fluid sections.
Functioning of the bladder-type accumulator
The bladder-type accumulator operates by utilizing the principle of elasticity of the bladder and the compressibility of the gas. When the hydraulic or pneumatic system is pressurized, the fluid enters the accumulator through the inlet port, compressing the bladder against the gas section.
The bladder is made of a durable and flexible material, such as rubber, that allows it to expand and contract while maintaining a tight seal. As the fluid enters, it displaces the gas, compressing it and storing energy in the system.
When there is a demand for fluid in the system, such as during peak load or sudden power requirements, the stored energy in the accumulator is released by allowing the fluid back into the system. This action pushes the bladder back towards the gas section, which compresses the gas and delivers the stored pressure energy to the system.
Advantages of using a bladder-type accumulator
The use of an accumulator with bladder offers several advantages in hydraulic and pneumatic systems. Firstly, it provides a means to store and release energy quickly, helping to meet sudden demands in the system, reducing pressure fluctuations, and improving system response time.
