Mini accumulator Diaphragm accumulators are a type of hydraulic accumulator. A diaphragm separates the compressible gas cushion from the hydraulic fluid. The diaphragm accumulator type AC is used as a source of pressurized oil. It supports or increases the pump delivery flow or stores pressure energy, e.g. for an accumulator charge circuit.
Accumulators usually are installed in hydraulic systems to store energy and to smooth out pulsations. Typically, a hydraulic system with an accumulator can use a smaller pump because the accumulator stores energy from the pump during periods of low demand. This energy is available for instantaneous use, released upon demand at a …

A hydraulic accumulator allows hydraulic systems to operate without the delays that may occur using a pump alone. They also help to increase the lifespan of hydraulic systems due to less pressure on components, such as seals and valves. With regard to gas pressure, hydraulic accumulators store fluid that''s fed into the system when required.
