Abstract
A method and apparatus for producing a very fast succession of identical well-defined drops, driven at very high speed, in which a jet of liquid which is divided into droplets by high-frequency vibration is produced at very high speed.
Claims24
A method of forming a very fast succession of identical and well-defined drops driven at a very high speed, comprising the steps of supplying a liquid under very high pressure of approximately 750 psi or greater to the inlet of a high pressure chamber, generating a very high speed jet of liquid under very high static pressure at the outlet of said high pressure chamber, and dividing said very high speed jet of liquid into a stream of drops by the application of high-frequency vibration at high power in a direction along the path of said jet of liquid.
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 of approximately 750 psi or greater, means for generating a high speed jet including 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.
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.
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.
