Hydropneumatic refers to the pneumatic (gas) and hydraulic (water) components needed for operation of the devices. Hydropneumatic accumulators or pulsation dampeners are devices which prevent, but do not absorb, alleviate, arrest, attenuate, or suppress a shock that already exists, meaning that these devices prevent the creation of a shock wave ...
Hydropneumatic suspension is a type of motor vehicle suspension system, invented by Paul Magès, produced by Citroën, and fitted to Citroën cars.The suspension was referred to as Suspension oléopneumatique [] in early literature, pointing to oil and air as its main components.
Heave compensation is motion compensator technology applied to minimizing the vertical movement of a load supported by lifting gear mounted on a heaving platform. Techniques include active heave compensation and passive heave compensation—the two traditional types of heave compensation—as well as balanced heave compensation.
A guideline tensioner is a hydropneumatic device used on an offshore drilling rig that keeps a positive pulling force on the guidelines from the platform to a template on the seabed. [ 1 ] The guidelines act as a guidance for equipment and tools that must be lowered to the template.
Active Body Control, or ABC, is the Mercedes-Benz brand name used to describe electronically controlled hydropneumatic suspension. [1] [2] This suspension improves ride quality and allows for control of the vehicle body motions, allowing for reduced body roll in many driving situations including cornering, accelerating, and braking.

In 1966, Rolls-Royce licensed Citroën's hydropneumatic system to fit to the rear axle of the Silver Shadow. [11] At first, both the front and rear of the car were controlled by the levelling system; the front levelling was removed in 1969 as it had been determined that the rear levelling did almost all the work.
Telescopic cylinders must only be used in machinery as a device for providing force and travel. Side forces and moment loads must be minimized. Telescopic cylinders should not be used to stabilize a structural component. [4] Hydraulic telescopic cylinders are often limited to a maximum hydraulic pressure of 2000-3000 psi.
Electrohydraulic servo valves may consist of one or more stages. A single-stage servo valve uses a torque motor to directly position a spool valve. Single-stage servo valves suffer from limitations in flow capability and stability due to torque motor power requirements.
