Description: |
| Abstract:
This invention relates to the art of internal combustion engines, and pertains more especially to an improved mechanism for forming and governing the explosive charges admitted to the engine-cylinder.
One object of the invention is to provide an improved device of the character stated, which will facilitate the running, of the engine alone or under light load with an economy of fuel, and prevent the stoppage of the engine through lack of sufficient fuel supply on occasions when the load is suddenly removed and the governing slide is practically closed to prevent the engine from racing.
Another object of the invention is to provide a means whereby the action of the centrifugal governor which controls the governing slide for the charge may be varied, so as to exert a greater or less closing action upon said slide under a given engine speed.
Claims:
1. In a charge-forming mechanism for engines, the combination with a mixing chamber having an air supply passage leading thereto and an oil supply nozzle projecting therein, of a valve controlling the communication of said mixing chamber with the induction passage of the engine, and a tube carried by said valve, said tube extending inwardly of the mixing chamber in a direction at right angles to said oil supply nozzle to a point adjacent to the delivery end of the latter and exerting a local suction thereon when the valve is closed, substantially as described.
2. In a charge-forming mechanism for engines, the combination with a mixing-chamber communicating on one side with the induction passage of the engine and on the other with the atmosphere, of an oil supply nozzle projecting upwardly into said mixing chamber, means for maintaining a supply of oil in said nozzle at a height below the delivery end thereof, a governor controlled slidable grid-valve between said mixing chamber and induction passage, and a tube carried by said valve and extending inwardly of the mixing-chamber, said tube being so mounted in the valve that when the latter is closed its outer end communicates with the induction passage while its inner end lies adjacent to the delivery end of said nozzle, producing a local suction effect upon the oil in the latter, and when said valve is opened, said tube is without substantial effect upon said delivery nozzle, substantially as described.
3. In a charge-forming mechanism for engines, the combination with a mixing-chamber formed with an air-supply passage, and communicating with the induction passage of the engine, of an oil-supply nozzle projecting upwardly into said mixing chamber, means for maintaining a supply of oil in said nozzle at a height below the delivery end thereof, a valve between said mixing chamber and induction passage, a tube carried by said valve and extending inwardly of the mixing chamber whereby to produce a local suction effect upon the delivery end of said nozzle when said valve is closed, a governor mechanism connected to and operating said valve according to the speed of the engine, and means for opposing the closing movement of said valve, substantially as described.
4. In a charge-forming mechanism for engines, the combination with a mixing chamber formed with an air-supply passage, and communicating with the induction passage of the engine, of an oil-supply nozzle projecting upwardly into said mixing chamber, means for maintaining a. supply of oil in said nozzle at a height below the delivery end thereof, a valve between said mixing chamber and induction passage, a tube carried by said valve and extending inwardly of the mixing chamber whereby to produce a local suction effect upon the delivery end of said nozzle when said valve is closed, a governor mechanism connecting to and operating said valve according to the speed of the engine, and adjustable elastic means for opposing the closing movement of said valve, substantially as described.
