2. Electro-hydraulic actuator - Wikipedia

   en.wikipedia.org/wiki/Electro-hydraulic_actuator

   The result is a "power-by-wire" system, where both the control and energy are sent through a single set of wires. [8] Redundancy can thus be provided by using two such units per surface, and two sets of electrical wires. This is far simpler than the corresponding systems using an external hydraulic supply.

3. Brake-by-wire - Wikipedia

   en.wikipedia.org/wiki/Brake-by-wire

   The hydraulic force generated by pressing the brake pedal is used only as a sensor input to the computer unless a catastrophic failure occurs including a loss of 12-volt electrical power. The brake actuator has an electric pump that provides the hydraulic pressure for the system, and valves to pressurize each wheel caliper to apply the friction ...

4. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   The mechanical feedback has been replaced by an electric feedback with a position transducer. Integrated electronics close the position loop for the spool. These valves are suitable for electrohydraulic position, velocity, pressure or force control systems with extremely high dynamic response requirements.

5. Hydraulic power network - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_power_network

   The hydraulic power network was not in competition with the electric power supply, but was seen as a supplement to it, and continued to supply power to many customer until the economic crisis of the 1930s, when the demand for pressurized water as an energy source declined. The last water engine was decommissioned in 1958. [31]

6. Hydraulic machinery - Wikipedia

   Hydraulic power pack; Transmission lines Hydraulic hoses; Passive components Hydraulic cylinders; For the hydraulic fluid to do work, it must flow to the actuator and/or motors, then return to a reservoir. The fluid is then filtered and re-pumped. The path taken by hydraulic fluid is called a hydraulic circuit of which there are several types.
