A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring , a raised weight , or a compressed gas .
Accumulators are a common part of hydraulic machinery. Their function is to store energy by using pressurized gas. One type is a tube with a floating piston. On the one side of the piston there is a charge of pressurized gas, and on the other side is the fluid. Bladders are used in other designs.
The device was a low-cost alternative to dry docks for maintenance and repair work. This became known as the Patent slipway or 'Heave-up Slip' and was patented in 1819 by shipbuilder Thomas Morton of Leith in Scotland. [5] The 1890 replacement was originally driven by an hydraulic engine powered by the dock's hydraulic system.
A pressure tank or pressurizer is a type of hydraulic accumulator used in a piping system to maintain a desired pressure. Applications include buffering water pressure in homes. Applications include buffering water pressure in homes.
