A device for generating fluid pulses, comprising: a first channel (C 1) with a first fluid inlet (R 1) and a second channel (C 2) with a second fluid inlet (R 2), wherein the first fluid inlet and second fluid inlet are essentially situated opposite each other, wherein the first channel (C 1) comprises a first control outlet (CP 1) at the height of the first fluid inlet (R 1), and the second channel (C 2) comprises a second control outlet (CP 2) at the height of the second fluid inlet (R 2), wherein the respective control outlet (CP 1, CP 2) is located in front of the respective fluid inlet in relation to the inflowing direction of the fluid inlet, wherein, during operation, a fluid flowing in through the first fluid inlet (R 1) passes through the first channel (C 1), and after running through the first channel (C 1), at least a portion of the introduced fluid exits the first channel (C 1) through the first control outlet (CP 1), thereby causing the inflowing fluid to be diverted toward the second fluid inlet (R 2), wherein, during operation, a fluid flowing in through the second fluid inlet (R 2) passes through the second channel (C 2), and after running through the second channel (C 2), at least a portion of the introduced fluid exits the second channel (C 2) through the second control outlet (CP 2), thereby causing the inflowing fluid to be diverted toward the first fluid inlet (R 1), characterized in that the first channel (C 1) comprises several working outlets (WP 1, WP 2), through which a portion of the inflowing fluid is removable, wherein in the fluid direction subsequent to the last working outlet of the first channel (C 1), the remaining portion of the introduced fluid exits the first channel (C 1) through the first control outlet (CPi), and wherein the cross sectional surface of the first channel (C 1) is abruptly reduced subsequent to a working outlet (WP 1, WP 2). a first channel (C 1) with a first fluid inlet (R 1) and a second channel (C 2) with a second fluid inlet (R 2), wherein the first fluid inlet and second fluid inlet are essentially situated opposite each other, wherein the first channel (C 1) comprises a first control outlet (CP 1) at the height of the first fluid inlet (R 1), and the second channel (C 2) comprises a second control outlet (CP 2) at the height of the second fluid inlet (R 2), wherein the respective control outlet (CP 1, CP 2) is located in front of the respective fluid inlet in relation to the inflowing direction of the fluid inlet, wherein, during operation, a fluid flowing in through the first fluid inlet (R 1) passes through the first channel (C 1), and after running through the first channel (C 1), at least a portion of the introduced fluid exits the first channel (C 1) through the first control outlet (CP 1), thereby causing the inflowing fluid to be diverted toward the second fluid inlet (R 2), wherein, during operation, a fluid flowing in through the second fluid inlet (R 2) passes through the second channel (C 2), and after running through the second channel (C 2), at least a portion of the introduced fluid exits the second channel (C 2) through the second control outlet (CP 2), thereby causing the inflowing fluid to be diverted toward the first fluid inlet (R 1), characterized in that the first channel (C 1) comprises several working outlets (WP 1, WP 2), through which a portion of the inflowing fluid is removable, wherein in the fluid direction subsequent to the last working outlet of the first channel (C 1), the remaining portion of the introduced fluid exits the first channel (C 1) through the first control outlet (CPi), and wherein the cross sectional surface of the first channel (C 1) is abruptly reduced subsequent to a working outlet (WP 1, WP 2).
