| 31. | Instrumentation products include actuators, controllers, and related software.
|
| 32. | The pressure in the actuator's chamber pushes the pistons away.
|
| 33. | An actuator nub presses on the flat spring near its hinge point.
|
| 34. | If the actuator is released this will move the flat spring upward.
|
| 35. | The aerodynamically balanced rudders are equipped with independent electrical actuators.
|
| 36. | The hydraulic circuit powers the actuators which then move the control surfaces.
|
| 37. | The actuators were powered by compressed air from bottles at the rear.
|
| 38. | Each hand consists of three fingers powered by four actuators.
|
| 39. | Recent advances in internal wastegate actuators bring dual port control.
|
| 40. | Others only push ( such as a cam actuator ).
