|Design Features and Benefits|
|Lightweight composite material for high strength & low weight|
|Dual seals for positive gas-fluid separation|
|Self-displacing to achieve max pressure differential|
|Self-lubricating for extended life cycling|
|Leak tight construction|
|Accessories easily added (Thermometer, pressure gauge, piston position indicator, pressure switches etc.)|
|Maintenance free bellows type aircraft accumulators|
Our positive displacement hydraulic aircraft accumulators are self contained sources of hydraulic power storing inert gas and hydraulic oil under pressure (nominally 3000 PSI). The expansion of the pressurized gas serves to expel the oil from the unit upon demand. The aircraft accumulator may also contain its own reservoir to receive low pressure oil from the system (self displacing) after being expelled from the high pressure side.
These units are used in: Aircraft engine start systems to provide the high pressure oil supply required to drive hydraulic motors of the auxiliary power unit (APUs). Primary applications are on aircraft, including helicopters, where minimum weight is of paramount importance.
- Hydraulic system backup power
- Hydraulic system fluid expansion
- Landing gear system
