a device that, by remote influence, can operate valves or other equipment.

n: A kind of brassboard method for controlling gas overflowing. When gas overflowing leading to underground blowout happens, an actuator will be threw into the drill column to open side opening of diverter valve.

n: a device on a diesel engines governor that increases the engines speed by increasing positive voltage going to the actuator and governor. As the engine needs more fuel to go faster, the direct-acting actuator increases positive voltage to make the governor increase the fuel flowing to the fuel injectors. See electrically actuated governor:

n: in drilling equipment the pressed air as working medium, assembling air supply device, controlling element, actuator and accessary with conduit line, general designation of main parts that realizes the driving and controlling the drilling machine.

n: a device that increases an engines speed by decreasing the positive voltage going to the electric actuator and governor. As the engine needs more fuel to go faster, the reverse-acting actuator decreases the positive voltage to make the governor increase the fuel. Compare direct-acting electric actuator. See governor.
