2. Electrohydraulic servo valve - Wikipedia

   en.wikipedia.org/wiki/Electrohydraulic_servo_valve

   A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump. It then transfers the fluid to a hydraulic cylinder in a closely controlled manner. Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.

3. Electro-hydraulic actuator - Wikipedia

   en.wikipedia.org/wiki/Electro-hydraulic_actuator

   Instead of the energy needed to move the controls being supplied by an external hydraulic supply, it is supplied over normal electrical wiring, albeit larger wiring than what would be found in a fly-by-wire system. The speed of the motion is controlled through the use of pulse-code modulation. The result is a "power-by-wire" system, where both ...

4. Hydraulic pump - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_pump

   Fluid flow in an external gear pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure).

5. Power steering - Wikipedia

   en.wikipedia.org/wiki/Power_steering

   Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...

7. Linear actuator - Wikipedia

   en.wikipedia.org/wiki/Linear_actuator

   The threads of a lead screw act as a continuous ramp that allows a small rotational force to be used over a long distance to accomplish the movement of a large load over a short distance. The power supply is from a DC or AC motor. The typical motor is a 12v DC, but other voltages are available.
