Product Code:SAE ARP4379
Title:Aerospace - Accumulator, Hydraulic, Cylindrical, Piston Separated
Issuing Committee:A-6c6 Power Sources Committee
Scope:This SAE Aerospace Recommended Practice (ARP) is intended as a guide in defining the requirements for aerospace piston separated hydraulic accumulators, including details pertinent to the design, fabrication, and performance of the accumulator. This type of accumulator has a piston separator and contains both high-pressure gas and fluid. The accumulator is used in aerospace hydraulic systems of the following types as defined in AS5440 with design operating pressures of up to 8000 psi (55,160 kPa). 驴 Type I: 65 to +160 掳F ( 54 to +71 掳C) fluid temperature驴 Type II: 65 to +275 掳F ( 54 to +135 掳C) fluid temperatureFor commercial aerospace or helicopter applications, the information and guidelines of ARP4752 or ARP4925 respectively, are considered.
