|  MIL-H-8891A
Criticaol performance parameter is the temperature envelope
NOTE :
of -65 to 390F.
Measurement of accumulator gas Pressure - A permanent
3.10.2.1
pressure gage shall be attached to the gas side of the accumulator. A
gage indicating accumulator gas pressure shall never be used to indicate
equivalent hydraulic pressure.
Accumulator accessibility - In all accumulator in-
3.10,2.2
stallations space shall be Provided around the gas charging valve for use
of a MIL-G-8348 high-pressure, gas-testing gage assembly and for standard
fitting connections to charge accumulators.
Accumulator instructions - Instructions for servicing
3.l0.2.3
the accumulator with gas pressure with the accumulator oil chamber discharged
shall be provided immediately adjacent to the accumulator, Adequate informa-
tion shall be included to indicate the proper gas preload pressure throughout
the temperature range for which the accumulator will be serviced.
Accumulator location - The accumulator in the vehicle
3.10.2.4
shall not be located near a hot air duct or other similar component that
may fail and result in the accumulator overheating.
Actuating cylinders - Hydraulic actuating cylinders
3.10.3
shall be so installed that they do not interfere with the adjacent structure
and are readily accessible for maintenance and inspection. If possible, the
cylinder should be installed in a protected area, or if exposed, be protected
from flying debris during landing and takeoff.
Bleeder valves - Bleeder valves shall be so located
3.10.4
that they can be operated without necessitating removal of other vehicle
components. Such installations shall permit attachment of a flexible hose
so that fluid bled off may be directed into a container.
Brake valves - Brake valves shall be installed in ac-
3.10.5
cordance with MIL-B-8584.
Check valves - Check valves shall conform to MIL-
3.10.6
V-25675.
Directional control valves - The installation of direc-
3.10.7
tional control valves shall be compatible with the control valve performance
such that the system operation will not be affected by back pressure, inter-
flow, or pressure surges which might tend to cause the valves to open or move
from their setting or cause them to bypass fluid in other than the intended
manner.
