ALBERTO BAGNULO, 0F TURIN, ITALY.
Application filed March 1-1, 1921. Serial No- 451,601.
To all whom it may concern:
Be it known that I, ALBERTO BAoNUno, a subject of the King of Italy, and resident of 13 Via Bogino, Turin, in the Kingdom of Italy, have invented certain new and useful Improvements in Carbureting Apparatus for Internal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
The present invention has for its object to provide a carbureting apparatus for internal combustion engines, which is particularly advantageous for use in connection with the engine forming the object of my Patent No. 1,423,705, dated July 25, 1922, and is characterized by the fact that it is divided into two chambers placed one above the other and separated by an automatic valve; in the upper chamber is conveyed by gravity the liquid fuel, the inlet of which can be adjusted by a hand-operated or automatic cock or the like; the lower spray chamber, constantly in communication with the combustion chamber of the engine, has its upper end flared upwards, while its lower end is conical, both ends being connected by a central throttled part. I
The scavenging of the carbureter is effected by the air automatically drawn in by the motor through the said carburetor said air facilitating moreover the passage of the fuel through the valve.
In the accompanying drawings the figore is an axial vertical section of a carbureter embodying my invention.
The automatic valve 1 is kept on its seat 2 by the spring 3, the tension of which can be adjusted by a nut and lock-nut The venturi or difl'user is placed under the valve 1 and is externally provided wings 6. As it appears it is internally flared at its upper end 7 and conical at its lower end 8, the intermediate part having a throttled point 9.
The chamber 12 placed before the automatic valve communicates at its upper part with the atmosphere through holes 11 in the bell 10. Into said chamber opens the pipe through which the fuel is conveyed by gravity from the tank placed at a higher level, where it is contained without pressure.
The needle valve 14:, placed at the pipe end 13 allows the fuel inlet into the chamber 12 to be'adjusted by hand by means of the hand wheel 15. The pipe 13 is suitably provided with cooling wings 5. The needle 14 of the valve through which the liquid fuel is fed to the carburetor being at a certain distance from this latter and a large cooling surface for the carburetor being provided by the wings of the venturi and pipe 13, all overheating and consequent elongations are prevented which could cause variations in the degree of aperture of said valve. v
The Venturi wings prevent moreover the fuel from carb oniz'ing through lack of air owing to the high temperature acquired.
'Into the carbureter chamber 12 opens the tuge 16 (provided with a cock not shown in the drawing) from which water drops on the valve 1 through an end spout 17 The bell 10 is provided at its upper end with a funnel 18 having holes 11 through which the priming petrol or the likemay easily be introduced into the chamber 12 in order to assist the engine in starting.
The edge 20 provided on the base of the bell 10, limits the eventual outflow of the fuel when starting the engine.
Claims:
1. A carbureting apparatus for internal combustion engines, comprising a receiving chamber having air-inlet ports and a discharge port, means for supplying fuel to said chamber, a throttling chamber communicating with the receiving chamber through the discharge port, and an elongated conical diffusing chamber communieating with the throttling chamber through a restricted opening in the bottom of the latter.
2. A carbureting apparatus for internal combustion engines comprising a receiving chamber having air-inlet ports and a discharge port, a valve controlling the discharge port, a throttling chamber communicating with the receiving chamber through the discharge port, an elongated conical diffusing chamber communicating with the throttling chamber through a restricted opening in the bottom of the latter, and
means for supplying water and fuel to the controlling thedischarge port, a throttling chamber having downwardly converging walls arranged below and communicating with the receiving chamber through the discharge port an elongated conical diffusing chamber arranged below the throttling chamber and communicating with the latter through a restricted opening in the bottom of the throttling chamber, and means for supplying water and fuel to the receiving chamber above the valve.
5. .A carbureting apparatus'for internal combustion engines comprising a receiving chamber having a discharge port in its bottom, a valve controlling the port, water and fuel supply conduits opening into the chamber above the valve, means for supplying air to the chamber, a throttling chamber having downwardly converging walls arranged below and communicating with, the receiving chamber through said discharge port, and an elongated conical diffusing chamber arranged below the throttling cham ber and communicating below the latter through a restricted opening in the bottom of said throttling chamber, said difiusing chamber being open at the bottom for communication with the combustion chamber of the engine.
In testimony that I claim the foregoing as my invention, I have signed my name.
ALBERTO BAGNULO.
