Abstract
Abstract A device for carburetion of liquid fuels including an ultrasonic oscillator and at least one fuel supply nozzle which supplies fuel into engagement with the oscillator. The oscillator is disposed in an air tube so that the fuel which is acted upon by the oscillator can be mixed with air to form a fuel-air mixture.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
A device for carburetion of liquid fuels comprising: an airflow tube; an oscillatory body disposed within said tube, said body terminating in a cup-shaped portion opening toward the down-stream end of said airflow tube, said cup-shaped portion having at least one air inlet opening through the side wall thereof; an electro-mechanical transducer coupled to said oscillatory body; a fuel supply nozzle disposed in the bottom of said cup-shaped portion for spraying fuel onto the inner walls thereof; means affording connection of said nozzle to a source of liquid fuel under pressure; and means for connecting said transducer to a source of electrical energy.
Claim 2
Independent Claim
103 words
A device for carburetion of liquid fuels comprising: an airflow tube; an oscillatory body disposed within said tube, said body terminating in a cup-shaped portion opening toward the down-stream end of said airflow tube, said cup-shaped portion having at least one air inlet opening through the side wall thereof; an electro-mechanical transducer coupled to said oscillatory body; a fuel supply nozzle disposed in the bottom of said cup-shaped portion for spraying fuel onto the inner walls thereof; means affording connection of said nozzle to a source of liquid fuel under pressure; and means for connecting said transducer to a source of electrical energy.
Claim 3
Dependent Claim
23 words
A device as defined by claim 1 in which said transducer is a piezo-electric ceramic body formed as a flexural bending mode oscillator.
Claim 4
Dependent Claim
38 words
A device as defined by claim 1 in which the air inlet openings in the side wall of said cup-shaped portion have their axes disposed at an angle to the plane of the cup bottom of about 45°.
Claim 5
Dependent Claim
41 words
A device as defined by claim 1 in which the axes of the air openings through the side wall of said cup-shaped portion are angularly disposed with respect to each other to produce a swirling motion of air within said portion.
Claim 6
Dependent Claim
47 words
A device as defined by claim 1 in which the air openings through the side wall of said cup-shaped portion are so positioned with respect to said fuel supply nozzle that the fuel is first gasified by oscillatory energy from said body and then mixed with air.
Claim 7
Dependent Claim
20 words
A device as defined by claim 1 in which said transducer is a modified lead-zirconate-titanate and said body is metallic.
Claim 8
Dependent Claim
45 words
A device as defined by claim 1 in which said body comprises a solid cylindrical portion and a cup-shaped portion, said cylindrical portion with the larger cross-sectional area oscillating at a small amplitude and said smaller cross-sectional area cup-shaped portion oscillating with a large amplitude.
Claim 9
Dependent Claim
26 words
A device as defined by claim 1 in which said oscillatory body comprises a solid cylinder and a cylindrical cup threadedly joined in an integral structure.
Claim 10
Dependent Claim
24 words
A device as defined by claim 1 in which said oscillatory body comprises a solid cylinder and a cylindrical cup which are integrally formed.
