Abstract
A fluid actuator for influencing the flow along a flow surface by ejecting a fluid flowing through the fluid actuator is described. The fluid actuator has at least two outlet lines with outlet openings at the respective ends thereof, and a feed line connected to the outlet lines for feeding fluid at a supply pressure, a flow direction diverting device into which the feed line opens and out of which the outlet lines open, and an adjusting device coupled to the flow direction diverting device to control the latter. The adjusting device is configured so the fluid is conducted successively in a cyclic sequence into each of the outlet lines. A discharge device for discharging a fluid out of a flow body, and a flow body having a multiplicity of discharge openings and a discharge device of said type are also described.
