<p>A device according to the invention comprises a first block (1) wherein a cavity (2) is arranged, said cavity being symmetric with respect to a plan PP' of which the side walls are provided with cylindrical grooves (3, 4, 3a, 4a, 7) and two planes (8 and 8a). It comprises a second block (10) which is fixed on the face (1a) of the block (1) and which carries moving parts (9a, 9b) mounted on micrometric screws (13, 13a). Said parts are made of an extra-hard material and comprise whistle blades (15, 15a) which are machined with precision and which cooperate with the grooves to define the fluid injection conduits (3, 3a), resonance cavities (4, 4a), a central conduit wherein a liquid is circulated and whistles (20 and 20a). One application is the mixture of a liquid fuel and combustion air before admission into a burner.</p> |
