Abstract
A gas jet actuator device is described for imparting controlled vibrations o an object to which the device is connected. The device comprises a conduit defining an inlet section which is connectible to a source of gas pressure, and a fork section downstream of the inlet section to define two or more diverging outlet sections disposed at predetermined angles. A nozzle is provided in the conduit upstream of the fork section a predetermined distance therefrom. A switching device is provided to cause a pressurized fluid jet stream from said nozzle to be directed to selected ones of the outlet sections by the Coanda effect to impart a controlled vibration force to an object to which the device is attached.
