- 9. device according to claim 6, wherein said ultrasonic generator means is situated in said chamber upstream from said injector.
- 10. A device according to claim 6, wherein said ultrasonic generator means comprises a generator producing a field whose wavelength is equal to the diameter of said injector nozzle.
- 11. A device according to claim 6, wherein said injector nozzle forms a reverse taper towards the exterior of said chamber in the direction of the path of said drops, said nozzle being wider at the exterior of said chamber than at the interior thereof.
- 12. A device according to claim 11, wherein said chamber is in the shape of a cylinder, the longitudinal axis of said cylinder being parallel to said path of said drops.
- 13. A device according to claim 12, wherein the wall of said cylinder through which said jet passes is perpendicular to said path of said drops.
- 14. A device according to claim 6, further including a container surrounding said injector nozzle and into which said drops enter, said container being kept at the vapor pressure of the liquid used and a sample disposed in said container to which said drops are directed.
- 15. A device according to claim 6, wherein said high pressure chamber is provided with at least one orifice disposed parallel to the longitudinal axis of the chamber and said means for supplying said chamber with liquid under high pressure supplies the liquid therethrough.
- 16. A device for forming a very fast succession of identical and well-defined drops at a very high speed, comprising a high pressure chamber; means for supplying said chamber with liquid under high pressure, one wall of said chamber forming an injector nozzle capable of providing a fast jet; and ultrasonic generator means for generating a high-frequency field focused at a given point in said liquid on the level of the origin of said jet; and further including at the output of said injector nozzle, means for supplying gas surrounding said drops and having the same speed as said drops.
- 17. A device for forming a very fast succession of identical and well-defined drops at a very high speed comprising a chamber supplied with liquid under very high pressure of approximately 750 psi or greater, means for generating a jet including one wall of said chamber forming an injector nozzle means for supplying a fast jet, said injector nozzle means being provided with means for generating an ultrasonic vibration along the axis of said injector nozzle means provided in the form of a magnetrostrictive element in surrounding relation thereto and connected to a source of high frequency.
- 18. A device according to claim 17, wherein said generating means generates a jet having a very high speed of approximately 100 meters/second or greater.
- 19. A device according to claim 17, wherein said source of high frequency provides a high-frequency of approximately 200 Kc/s or greater. pg,30
- 20. A device according to claim 17, wherein said injector nozzle means forms a reverse taper towards the exterior of said chamber in the direction of the path of said drops, said nozzle means being wider at the exterior of said chamber than at the interior thereof.
- 21. A device according to claim 20, wherein said chamber is in the shape of a cylinder, the longitudinal axis of said cylinder being parallel to said path of said drops.
- 22. A device according to claim 21, wherein the wall of said cylinder through which said jet passes is perpendicular to said path of said drops.
- 23. A device according to claim 17, characterized in that it includes, at the output of said injector nozzle means, means for supplying gas surrounding said drops and having the same speed as said drops.
- 24. A device according to claim 17, further including a container surrounding said injector nozzle means and into which said drops enter, said container being kept at the vapor pressure of the liquid used and a sample disposed in said container to which said drops are directed.
