  2. Hydraulic accumulator - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_accumulator

    [note 1] An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations. It is a type of energy storage device. Compressed gas accumulators, also called hydro-pneumatic accumulators, are by far the most common type.

  3. Hydropneumatic device - Wikipedia

    en.wikipedia.org/wiki/Hydropneumatic_device

    Gas cushion (spring) pre-filled accumulators of liquids are called hydropneumatic accumulators. "Hydro" because a liquid (like water) is involved. "Pneumatic" because a gas (like air) is involved. "Accumulator" because the purpose is to store or accumulate liquid volume by easy compression of the gas.

  5. Accelerator Coaster - Wikipedia

    en.wikipedia.org/wiki/Accelerator_Coaster

    The compressed nitrogen in the accumulators forces the hydraulic fluid into the turbines that drive the winch. As the winch winds in the launch cables, the retractor cable is unwound from the winch. After the train moves off the electrical contacts in the launch area, its launch dog is held down only by the force of the accelerating catch-car.

    en.wikipedia.org/wiki/Heron's_fountain

    Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [ 1 ] Heron studied the pressure of air and steam, described the first steam engine , and built toys that would spurt water, one of them known as Heron's fountain.

  9. Active heave compensation - Wikipedia

    en.wikipedia.org/wiki/Active_heave_compensation

    [4] [5] Hydraulic "active boost" winches control the oil flow from the pump(s) to the winch so that the target position is reached. Hydraulic winch systems can use accumulators and passive heave compensation to form a semi-active system with both an active and a passive component. In such systems the active part will take over when the passive ...
