Device for generating fluid pulses

1. A device for generating fluid pulses, comprising:

a first channel with a first fluid inlet, a first working outlet, a second working outlet, and a first control outlet, the first control outlet located in front of the first fluid inlet in relation to an inflowing direction of fluid to the first fluid inlet, the first channel including at least one working outlet through which a portion of the inflowing fluid is removable; and

a second channel with a second fluid inlet and a second control outlet, the second fluid inlet substantially situated opposite the first fluid inlet and the second control outlet located in front of the second fluid inlet in relation to an inflowing direction of fluid to the second fluid inlet,

wherein, during operation, a fluid flowing in through the first fluid inlet passes through the first channel, and after running through the first channel, at least a portion of the introduced fluid exits the first channel through the first control outlet, thereby causing the inflowing fluid to be diverted toward the second fluid inlet, and a fluid flowing in through the second fluid inlet passes through the second channel, and after running through the second channel, at least a portion of the introduced fluid exits the second channel through the second control outlet, thereby causing the inflowing fluid to be diverted toward the first fluid inlet,

wherein, in the fluid direction subsequent to the last working outlet of the first channel, the remaining portion of the introduced fluid exits the first channel through the first control outlet,

wherein the cross sectional surface of the first channel is abruptly reduced between the first working outlet and the second working outlet and subsequent to the first working outlet, and

wherein the first channel expands subsequent to the abrupt reduction and ahead of the second working outlet between the abrupt reduction and the second working outlet.

2. The device according to claim 1 , wherein the first and second working outlets branch away from the first channel at an angle to a primary channel direction or substantially perpendicular to the primary channel direction.

3. The device according to claim 1 , wherein the first and second working outlets comprise different cross sectional surfaces.

4. The device according to claim 1 , wherein the second channel is structured symmetrically to the first channel.

5. The device according to claim 1 , wherein the second channel is structured asymmetrically relative to the first channel.

6. The device according to claim 5 , wherein the cross sectional surface of the second channel differs from the cross sectional surface of the first channel.

7. The device according to claim 5 , wherein the time it takes to pass through the first channel differs from the time it takes to pass through the second channel given an identical fluid supply.

8. The device according to claim 1 , wherein the device is a control stage of a fluid actuator for influencing a fluid flow along a flow surface.

9. The device according to claim 1 , wherein the device directly influences a fluid flow along a flow surface.

10. The device according to claim 1 , wherein the device provides a pulsed liquid jet.

11. The device according to claim 1 , wherein the device provides a pulsed fluid stream comprising a fuel or a fuel-air mixture for subsequently burning the pulsed fluid stream.

12. The device according to claim 1 , wherein the device provides a pulsed fluid stream for cooling turbine blades or combustion chamber walls.

13. The device according to claim 1 , wherein the first channel and the second channel comprise a different capacity for fluid flow.

14. The device according to claim 2 , wherein the primary channel direction is not a straight line.

15. A device for generating fluid pulses, comprising:

a first channel with a first fluid inlet and a first control outlet, the first control outlet located in front of the first fluid inlet in relation to an inflowing, direction of fluid to the first fluid inlet, the first channel including at least one working outlet through which a portion of the inflowing fluid is removable; and

a second channel with a second fluid inlet and a second control outlet, the second fluid inlet substantially situated opposite the first fluid inlet and the second control outlet located in front of the second fluid inlet in relation to an inflowing direction of fluid to the second fluid inlet,

wherein, during operation, a fluid flowing in through the first fluid inlet passes through the first channel, and after running through the first channel, at least a portion of the introduced fluid exits the first channel through the first control outlet, thereby causing the inflowing fluid to be diverted toward the second fluid inlet, and a fluid flowing in through the second fluid inlet passes through the second channel, and after running through the second channel, at least a portion of the introduced fluid exits the second channel through the second control outlet, thereby causing the inflowing fluid to be diverted toward the first fluid inlet,

wherein, in the fluid direction subsequent to the last working outlet of the first channel, the remaining portion of the introduced fluid exits the first channel through the first control outlet, and

wherein the at least one working outlet further comprises at least two working outlets, wherein each of the at least two working outlets comprise different cross sectional surfaces.
