FLUID ACTUATOR FOR INFLUENCING THE FLOW ALONG A FLOW SURFACE, AS WELL AS BLOW-OUT DEVICE AND FLOW BODY COMPRISING A LIKE FLUID ACTUATOR

摘要

The invention relates to a fluid actuator for influencing the flow along a flow surface by ejection of a fluid. By means of a like fluid actuator a continuous flow is distributed to at least two outlet openings in order to generate fluid pulses out of these outlet openings. Control of this distribution takes place inside an interaction chamber supplied with fluid flow via a feed line. Into this interaction chamber there merge at least two control lines via control openings to which respective different pressures may be applied. The flow in the interaction chamber is distributed to the individual outlet openings as a function of the pressure difference at the control openings.
