ACCUMULATOR
IDENTIFICATION
FIN: 1070GM
LOCATION
ZONE: 146
DESCRIPTION
The accumulator is of the cylindrical type with an
internal bladder. The metal body has an outer layer
of kevlar to make it stronger. The accumulator is
precharged with nitrogen to 130bar (1885psi) at 20oC.
It holds 1liter (0,26 US gal) of usable fluid when it
is full. The bladder is made of rubber and isolates
the nitrogen gas from the hydraulic fluid. A nitrogen
charging valve (shrader type) and a direct reading
pressure gage are installed on the accumulator.
