2. Classified according to the primary energy working medium used by
electro-hydraulic energy.
(a) Gas generated by solid–gas generator is used as a primary energy
source. Such as Sparrow series gas turbine generator, gas turbocharged
accumulator; such as Aspide gas turbine driven generator hydraulic
pump.
(b) Gas generated by liquid gas generator is used as a primary energy
source. For example, SA-2 series gas turbine propellant delivery pump,
Sea Javelin gas motor hydraulic pump.
(c) High-pressure cold air is used as a primary energy source. For example,
Sam 3 (SA-3), Sam 6 (SA-6) cold air turbogenerator, Sparrow series of
high-pressure nitrogen pressurized accumulator.
(d) Ram air is used as a primary energy source, such as some types of
impact turbine driven alternator fuel transfer pump.
(e) Batteries are used as primary energy sources, such as Patriot DC motor
driven pressure compensation variable hydraulic pumps.
