actuator
A device that has a mechanical arm that extends and retracts. Actuators
control elements that are not OFF or ON. Instead, they vary by a
percentage. For example, inlets can be open various distances from 0 to
100 percent.
Typically, linear actuators connect directly to the inlets, or connect using
cables and pulleys. Inlets are usually located in ceilings or walls. Inlet
systems are often spring loaded to help close the inlets, or counter
weighted to help open the inlets.
