	Accumulator - Wikipedia, the free encyclopedia
		Accumulator (computing), in a CPU, is a processor register in which intermediate results are stored.
		Hydraulic accumulator, an energy storage device using a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure by an external source.
		Accumulator (air conditioning), a refrigerant storage and dehydration element of an air conditioning system.

	Hydrotrole - Hydraulic Accumulators and Hydropneumatic Accumulators
		The pressure generated by a spring-loaded accumulator depends on the initial loading and spring rate of the spring, and thus is not constant throughout the stroke of the piston.
		Accumulators of this type are compact and light, but best suited to systems where demand is intermittent and the fluid volumes required from the accumulator flow are not very large, as this type of accumulator is not normally made in large sizes.
		An accumulator is a convenient source of pressure to operate a holding device at constant pressure, regardless of demand from other sections of the system, or for maintaining a high working pressure on a workpiece during a long stand-by period.

	Accumulators - part 2
		An accumulator used with remote gas storage generally has the same size port at the gas end as at the hydraulic end to allow unimpeded flow of gas to and from the gas bottle.
		Multiple accumulators mounted on a common manifold are needed to achieve flows that are greater than 600 gpm.
		Bladder accumulators should be used for applications requiring less than a 25-ms response, and either type when response of 25 ms or greater is adequate.

	Accumulators - part 1
		Accumulators also can act as surge or pulsation absorbers, much as an air dome is used on pulsating piston or rotary pumps.
		Accumulator charging then begins when hydraulic fluid is admitted into the fluid side, and occurs only at a pressure greater than the precharge pressure.
		Piston accumulators of a particular capacity often are supplied in a choice of diameters and lengths, Table 1.

	Basics of Design Engineering - Fluid Power Chapter 5 - Accumulators, Compressors and Vacuum Pumps - Accumulators
		Diaphragm accumulators are usually comprised of a spherical or cylindrical pressure vessel, containing the separating element -- an elastomeric diaphragm.
		In other words, for an accumulator with a maximum operating pressure of 3,000 psi, minimum gas-precharge pressures would be 300 psi for threaded, 375 psi for welded, and 750 psi for bladder types.
		Accumulators with a higher pressure ratio are more efficient because they have a greater volume of usable fluid.

		Accumulators are to a hydraulic system what starting batteries are to engine systems; they both store energy for future use and both can become discharged and must be recharged.
		The broad range of equipment on which accumulators are used translates ham a need for knowledge of what they are, how they work, where they are likely to be located, their potential failure modes and their maintenance procedures.
		The fluid storage pressure in a gravimetric accumulator is constant and proportional to the weight and the area of the piston.

	Steam Accumulators : Spirax Sarco Learning Centre
		In practice the steam accumulator volume is based on the storage required to meet a peak demand, with an allowable pressure drop, whilst still supplying clean dry steam at a suitable steam release velocity from the water surface.
		The pipework between the boiler and the steam accumulator should be sized, as per normal practice, on a steam velocity of 25 to 30 m/s and the maximum output of the boiler.
		Water in the steam accumulator is steam that has condensed and is therefore clean and pure, with a typical TDS level of 20-100 ppm (compared with a shell boiler TDS of seldom less than 2 000 ppm) which promotes a clean and comparatively stable water surface.

	ORGONE ACCUMULATORS: A Skeptical Scrutiny of the Works and Theories of Wilhelm Reich
		Thus, the air whose temperature was measured by the accumulator thermometer (the thermometer on the right) is inside an insulated box where the warm air would have risen to the top, which is where the thermometer was.
		One should be able to poke some holes in the bottom of the accumulator to let air in, place a small turbine over the top of the accumulator, connect the turbine to an electric generator, and let the rising heated air generate free electricity for you.
		Or: poke a hole in the side of an accumulator and plug it up with a Peltier-Seebeck device (an array of thermocouple junctions) with one side facing the allegedly-warmed interior of the accumulator and the other side facing the cooler outside air, for instant electricity with no moving parts.

	Apex Hydraulics Ltd, fawcett christie hydraulics accumulators.
		Using an accumulator as an energy storage device effectively reduces the required flow rate capacity of the hydraulic pump, this results in a reduction of the installed power.
		The energy stored in an accumulator is used to avoid the accidental interruption of the working of the power generator by guaranteeing continuity of the safety function for a specific time.
		Accumulators are pressure vessels and therefore carry strict guidelines as to their manufacture and repair.

	Orgonics Wilhelm Reich Orgone Accumulators and Products
		Reich believed that the main contribution of his discovery of the orgone energy accumulator was aiding in the prevention of severe biopathic disturbances.The increased orgone energy recharges the red blood cells and tissues which may reverse the cellular degeneration from a T-bacilli reaction to the healthier bion reaction, thereby improving the entire body's resistance.
		The construction of an orgone accumulator is basically the layering of organic and metal materials, with a metal layer closer to the body to repel and direct the energy towards the user.
		Reich felt the orgone accumulators were best as a preventative by keeping the energy level strong enough to prevent the onset of a shrinking biopathy, and to reverse it in the early stages or prevent tumor spreading by keeping the surrounding tissues charged.

		In general, you should always try to solve a problem without accumulators (using plain structural or generative recursion), and only add accumulators when it (i) simplifies the structure of the solution, (ii) fundamentally improves the asymptotic running time of the program, or (iii) converts a program to tail-recursive form.
		In the first two examples from class, we used an accumulator to reduce the asymptotic complexity of the solution from O(n^2) to O(n).
