Abstract
Abstract A carburetor for motor vehicle internal combustion engines in which an annular atomizing chamber is formed between two axially aligned circular walls which are axially slidable relatively to each other to vary the size of the atomizing chamber so that no individual throttle valve for the fuel mixture is required. The air for atomizing the fuel is conducted into the annular atomizing chamber by two axially aligned tubular conduits leading from opposite sides through the center portion of the circular walls where a spherical body is fixedly arranged and in whose hollow interior extends a needle-valve controlled fuel admitting tube, while fuel outlet apertures in the sphere discharge the fuel into the airstream which is caused to flow from the tubular conduits into the annular atomizing chamber through a short and narrow and adjustable passage formed between the surface of the sphere and the adjustable circular walls.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
140 words
A device for preparing atomized fuels, comprising a housing, means forming in said housing a variable atomization zone comprising an axially symmetrical structure including two parallel walls forming between the same an annular tunnel for receiving the atomized fuel, means for connecting said atomization zone with an air supply means, means for adjusting the cross section of said atomization zone in relation to the amount of fuel required, means for feeding separately air and fuel to the center of said atomization zone, and means for tangentially discharging the prepared atomized fuel from said annular tunnel, said means for adjusting the cross section of said atomization zone including at least one of said walls, means for axially adjustably mounting said wall, and means for axially adjusting said wall relatively to the other for changing the cross section of said atomization zone.
Claim 2
Independent Claim
140 words
A device for preparing atomized fuels, comprising a housing, means forming in said housing a variable atomization zone comprising an axially symmetrical structure including two parallel walls forming between the same an annular tunnel for receiving the atomized fuel, means for connecting said atomization zone with an air supply means, means for adjusting the cross section of said atomization zone in relation to the amount of fuel required, means for feeding separately air and fuel to the center of said atomization zone, and means for tangentially discharging the prepared atomized fuel from said annular tunnel, said means for adjusting the cross section of said atomization zone including at least one of said walls, means for axially adjustably mounting said wall, and means for axially adjusting said wall relatively to the other for changing the cross section of said atomization zone.
Claim 3
Dependent Claim
35 words
A device according to claim 1, including means for regulating the amount of fuel which is introduced centrally into said atomization zone in relation to the adjusted size of cross-sectional area of said annular tunnel.
Claim 4
Dependent Claim
32 words
A device according to claim 1, including means for regulating the dosage of said fuel which is centrally introduced into said atomization zone in relation to the low pressure in said zone.
Claim 5
Dependent Claim
34 words
A device according to claim 1, including means for regulating the dosage of said fuel which is centrally introduced into said atomization zone in relation to the amount of air passing through said zone.
Claim 6
Dependent Claim
54 words
A device according to claim 1, in which the means for supplying fuel to the center of said atomization zone is provided with means for returning some of said fuel to the place of supply in relation to the amount of air required for atomization of the amount of fuel in said atomization zone.
Claim 7
Dependent Claim
37 words
A device according to claim 1, in which at least one of said axially adjustable walls is provided with an annular elastic portion which is fixedly connected to a circumferential wall of said housing of said carburetor.
Claim 8
Dependent Claim
43 words
A device according to claim 1, including a hollow displacement body arranged between said two walls at the center thereof, means for supplying fuel to the interior of said body, said body being provided with a nozzle aperture communicating with said atomization zone.
Claim 9
Dependent Claim
36 words
Device according to claim 1, including means for regulating the amount of the prepared fuel mixture which is conducted to an internal combustion engine in relation to the pressure measured between the device and said engine.
Claim 10
Dependent Claim
36 words
Device according to claim 1, including a fuel dosing means and an electronic computer which in accordance with the amount of air passing through said annular tunnel produces a control pulse which actuates said fuel-dosing meaNs.
Claim 11
Dependent Claim
64 words
Device according to claim 1, including a fuel-dosing means and an electronic computer which in accordance with the amount of air passing through said annular tunnel produces a control pulse which actuates said fuel-dosing means, said computer including means for rendering effective other factors such as temperature, barometric pressure and humidity which modify the atomized fuel which is tangentially discharged from said annular tunnel.
Claim 12
Dependent Claim
75 words
Device according to claim 1, including a fuel dosing means and an electronic computer which in accordance with the amount of air passing through said annular tunnel produces a control pulse which actuates said fuel-dosing means, said computer including means for controlling the admission of an additional amount of fuel required for starting a cold engine and also being adapted to close down the feed of fuel when the engine is to be made inoperative.
Claim 13
Dependent Claim
18 words
A device according to claim 1, including a mechanically operated air blower connected with said air supply means.
Claim 14
Dependent Claim
69 words
A device according to claim 1, including a mechanically operated air blower connected with said air supply means, the output of said blower being connected with an air input tube leading to said atomization zone, and a valve controlling a branch pipe leading from said air output tube to the input side of said blower, said valve controlling said branch pipe being adjusted by a manually operable foot pedal.
Claim 15
Dependent Claim
44 words
A device according to claim 1, including means for axially adjusting said two walls relatively to one another in relation to the low pressure produced by the air admitted to said atomization zone at the point where the fuel is introduced into said zone.
Claim 16
Dependent Claim
30 words
A device according to claim 1, including means for axially adjusting said two walls relatively to each other in relation to the amount of air admitted into said atomization zone.
