Aircraft Accumulators

Description

Positive displacement hydraulic accumulators serve as self-contained sources of hydraulic pressure. Our gas-charged piston-based accumulators allow hydraulic systems to quickly respond to changes in pressure demand and can also smooth out pulsation from pumps and other cycling devices up and downstream. Using accumulators often allows for the use of smaller pumps, providing for a lower system weight and footprint. Our innovative design features a hydraulic reservoir made with a proprietary composite fiber wrapping over a thin metal sleeve. This provides for pressure ratings to 3000 PSIG, while saving up to 40% of the weight found in competitive products. Dual piston seals provide for positive separation of the charging gas from the process media.

Application

Our positive displacement hydraulic accumulators are used in hydraulic applications are used as emergency backup hydraulic power for landing gear and braking systems.

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
