The function of accumulator in hydraulic system is to receive and store excess oil pumped through the system, which is used to compensate sudden increase in loads.

A hydraulic accumulator contains a bladder filled with a compressible gas, usually nitrogen. The pressure of the gas in the bladder is known as the pre-charge, and will vary based on the ambient temperature. Hydraulic oil is pumped into the accumulator but outside of the bladder. As the oil is pumped in, the bladder compresses, which exerts a force on the oil. There is usually an pressure transducer in the system which will signal the hydraulic pump to turn off when a certain oil pressure is reached in the accumulator. A hydraulic accumulator can have several uses. It can be used to store hydraulic pressure for later use. It can be also used as a type of "shock absorber" for hydraulic systems.

A clutch accumulator is a hydraulic device used in automatic and semi-automatic transmission systems to store and release hydraulic fluid. It helps maintain consistent pressure in the clutch system, ensuring smooth engagement and disengagement of the clutch during gear shifts. By absorbing shocks and fluctuations in hydraulic pressure, the accumulator enhances the overall performance and longevity of the transmission system.
In mobile hydraulics, those used in agricultural, industrial, and automotive applications a hydraulic accumulator works like a shock absorber for a hydraulic system. Often a hydraulic accumulator is composed of a housing with a diaphragm between the oil side and the gas side. Pressurized gas (usually dry nitrogen because of its low expansion/contraction properties in relationship to temperature). The accumulator will have a specification for the gas pressure and the hydraulic system can often be used to manipulate the pressure of the oil used in the accumulator depending upon a specific application. Rapid increases and decreases for hydraulic power demands (most often occurring in open-center systems) can shock the hydraulic pump, lines and valves. Open-center positive-displacement systems (constantly providing hydraulic flow while the engine is running) must return to sump when there is no hydraulic need. This is done by use of a relief valve or a 'dump'-valve on the pressure side of the system. There are moments when the relief valve may have a very slight delay. This delay can cause the system to build pressure in a very short period of time and this can strain hydraulic components. So the accumulator it used to soften the blow just a little. Another example would be when using a float application with a hydraulic system, an accumulator may help to buffer the changing oil directions within the hydraulic system.
A hydraulic accumulator is a device wherein its main function is to store energy in an efficient way. It does this by temporarily removing the stresses and pressures of external sources such as gasses. There are other types of accumulators as well.
Most hydraulic systems do not have accumulators.
A hydraulic accumulator is an energy storage device. It is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure by an external source. That external source can be a spring, a raised weight, or a compressed gas. The main reasons that an accumulator is used in a hydraulic system are so that the pump doesn't need to be so large to cope with extremes of demand, so that the supply circuit can respond more quickly to any temporary demand and to smooth pulsations.
Have an ASE certified technician in an EPA certified service shop do it. This task involves recovery and storage of the refrigerant in the system - purging the system in a manner which releases it into the atmosphere is illegal under federal law. Then the accumulator can be removed. If you remove the accumulator, you'll need to replace it.
A self-displacing accumulator is a type of hydraulic accumulator that uses the fluid to displace a piston or diaphragm to store energy. This design eliminates the need for an external gas charge and allows for more compact and simplified hydraulic systems.

Typically, the clutch accumulator restricts the flow of fluid upon engaging the clutch so that you do not risk "dumping the clutch" and putting undue strain on your pressure plate and hydraulic clutch system. I typical performance mod on some cars is to bypass or delete the accumulator for faster shifts and a truer clutch "feel." Do not remove the accumulator without thorough research on how it will affect your particular make and model.
