Abstract
Electro-hydraulic servo-valves and related methods are disclosed herein. An example electro-hydraulic servo-valve includes an inlet to receive a fluid from a reservoir, a torque motor, a chamber, the fluid to return to the reservoir via the chamber, and a flexure tube coupled to the torque motor. At least a portion of the flexure tube is disposed in the chamber. The flexure tube includes a nozzle to deliver the fluid to an actuator. The example electro-hydraulic servo-valve includes a damper operatively coupled to the flexure tube. The damper is disposed in the chamber.
Claims20
A system comprising:
- an electro-hydraulic servo-valve, the electro-hydraulic servo-valve including:
- a first damper;
- a second damper;
- and
- a coupler disposed between the first damper and the second damper;
- and
- processor circuitry to cause the coupler to operatively couple the first damper and the second damper to provide for damping at the electro-hydraulic servo-valve via the first damper and the second damper.
4 more elements
An apparatus comprising:
- a first damper including a driving member and a driven member, the driven member to pivot in response to movement of the driving member;
- a second damper including a shaft and a vane, the vane to control movement of a fluid in response to rotation of the shaft;
- and
- a coupler to operatively couple the first damper to the second damper via the driven member and the shaft.
