Abstract
A fluidic system is disclosed. The system comprises a plurality of fluidic oscillatory actuators, and at least one synchronization conduit connecting two or more of the actuators such as to effect synchronization between oscillations in the two or more connected actuators.
Claims23
A fluidic system, comprising:
- a plurality of fluidic oscillatory actuators, each actuator having a joining channel, a pair of control ports at opposite sides of said joining channel, and a feedback conduit directly connecting said control ports of said pair to each other;
- and
- a plurality of external synchronization conduits connecting at least two of said actuators, wherein for at least two of said external synchronization conduits, each conduit directly connects control ports that are on the same side of a respective joining channel.
A method of synchronizing fluidic oscillatory actuators, each having a joining channel and a pair of control ports at opposite sides of the joining channel, the method comprising:
- establishing fluid flow within a plurality of external synchronization conduits connecting at least two actuators, wherein for at least two of said external synchronization conduits, each conduit directly connects control ports that are on the same side of a respective joining channel;
- and
- for at least one of said actuators, establishing a feedback fluid flow between control ports at opposite sides of a respective joining channel of said actuator.
