Explosive Engine
|
Arthur H. Goldingham |
New York, NY |
Claim:
The combination with two four-cycle engines arranged to make their explosive strokes alternately and having their pistons moving in unison, of a single, single-acting, fuel-pump making a delivery-stroke at each revolution of the main shaft of the engine, a delivery-pipe therefor having branches leading to the cylinders and a delivery-valve in each branch as described, whereby the delivery-valve to one cylinder may yield to admit the passage of fuel while the other is held closed by the explosion pressure in its cylinder. |

Atomizing Spray Nozzle
|
Alessandro Franchetti |
New York, NY |
Abstract:
My improved atomizing spray nozzle is designed for use with oil engines in which the atomized fuel is injected into the working cylinder of the engine through a suitable valve by means of compressed air, and the purpose of my invention is to provide a simple and effective device for rapidly and completely atomizing the oil so as to supply the requisite spray of oil in the working cylinder of the engine.
My improved atomizing spray nozzle is designed for use in oil engines in which the atomized fuel oil is injected into the working cylinder of the engine through a suitable valve by means of compressed air, and the purpose of my invention is to provide a simple and effective device for rapidly and completely atomizing the oil so as to supply the requisite spray of oil in the working cylinder of the engine.
The essential feature of my invention consists in providing two or more ducts or passageways leading from the oil and compressed air supplies and intersecting each other at a plurality of points, and leading to a common nozzle outlet for the escape of the resulting spray of oil. The action of the compressed air passing through the intersecting ducts or passages draws the oil through said passages and at the points of intersection breaks up the oil into its atoms and thoroughly mixes it with the compressed air, this mixing and atomizing effect taking place over and over again at the successive intersections of the ducts or passageways until the action is complete when the mixture arrives at the nozzle outlet. By this means the atomizing of the oil can be accomplished with great speed. As a modification of this broad idea, I sometimes provide one or more charged spaces or chambers in the series of intersecting ducts or passageways with the result of the change in speed of the passing compressed air and oil mixture from the small ducts or passageways to the enlarged spaces, and from the spaces back to the small ducts or passageways, and of storing a small quantity of fuel in these spaces so that, as to time, the opening of the spray valve may be independent of the working stroke of the fuel pump. By the continual crossing and re-crossing of the compressed air and oil in the process of atomizing and mixing, the oil is completely broken up into its atom with the use of a relatively small quantity of compressed air.
Claims:
1. An atomizing spray nozzle having a plurality of intersecting ducts or passageways, a common spray outlet communicating with the ducts or passage-ways and intervening chambers or recesses of larger capacity than the ducts or passage-ways in which the fuel is stored when the common spray outlet is closed.
2- An atomizing spray nozzle comprising a nozzle casing having a spray outlet, a piston filling within the nozzle casing and provided with a plurality of intersecting grooves or channels in its periphery, inlets to the casing for oil and compressed air, and a valve controlling the flow through the nozzle.
3. An atomizing nozzle comprising a casing having a spray outlet and compressed air and oil inlets, a needle valve controlling the spray outlet, and a piston mounted upon the needle valve and formed with a plurality of intersecting grooves or channels in its periphery for the passage and mixing of the air and oil.
4. An atomizing spray nozzle comprising a casing having a spray outlet and compressed air and oil inlets, a needle valve controlling the spray outlet, means for operating the needle valve, and a piston mounted upon the needle valve stem and formed in the periphery with a plurality of intersecting grooves or channels, and a plurality of circumferential grooves for the purpose set forth.
