Description Component
Distributes hydraulic fluid between the HPU and the control manifold.
It also has fittings for accumulators and filters. Main manifold 1
Distributes hydraulic fluid to and from a single hydraulic channel. A
hydraulic channel is usually associated with an actuator and a Control manifold 2
servovalve. The control manifold also contains a low-pressure solenoid
valve, a high-pressure solenoid valve, a main valve, a slow turn-on
valve, and a pressure gage.
Sets the low-pressure output of the hydraulic channel. Low-pressure
adjustment 3
Allows low-pressure hydraulic fluid to be output to the hydraulic
channel. Low-pressure solenoid
valve 4
Allows high-pressure hydraulic fluid to be output to the hydraulic
channel. High-pressure solenoid
valve 5
Filters the hydraulic fluid as it is input to the main manifold. Main filter 6
Filters the hydraulic fluid as it is input to the pilot pressure circuit. Pilot pressure filter 7
Reduces pressure and flow fluctuations resulting from changing system
demands. Pressure accumulator 8
Reduces pressure and flow fluctuations resulting from changing system
demands. Return accumulator 9
Reduces pressure and flow fluctuations at the pilot pressure port. Pilot pressure
accumulator 10
Indicates system hydraulic pressure. Pressure gage 11
