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 ). <EOS>
