This invention relates to auxiliary atomizers for internal combustion engines and more particularly to a device of this character adapted to be attached to the intake valve of the engine.

A further object of the invention is to provide a device of this character which will not interfere with the flow of the atomized fuel to the cylinders of the engine and which will tend to thoroughly break up any unatomized particles of fuel which are cutering the cylinder.

A further object of the invention is to provide a device attached to the stem of the ordinary poppet valve of an internal combustion engine and operating in the port, which the poppet valve closes, which substantially bridges the port and which is so formed that unatomized particles of fuel coming into contact therewith are broken up before their entry into the cylinder.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure l is a vertical sectional view through a portion of an internal combustion engine having a poppet valve embodying an atomizer 3O constructed in accordance with my invention;

Figure 2 is a section through the poppet valve stem looking down upon the atomizer;

Figure 3' is a sectional view showing a further method of attaching the atomizer to the poppet valve stem.

Referring now more particularly to the drawings, the numeral 10 generally designates a poppet valve of an internal combustion engine opening into a cylinder or combustion space 11 to admit fuel therein. This valve, as in the usual engine construction, coacts with a seat 12 formed at the inner end of a port 13 connecting the combustion space 11 with a gas inlet space 14 to which gas is introduced from the carbureter (not herein shown). The port 13 isusually formed by counterboring the wall 15, separating the combustion space from the gas inlet space and accordingly the walls of this port are usually straight and concentric with the stem a guide 17 formed in the opposite wall 18 of the gas inlet space and'is accordingly 'held against transverse movement. I

In accordance with my invention, I secure to the stem ofthe valve, either integrally as shown at 19 in Figure 1 or by means of a set-screw 21, as shown in Figure 3, the smaller end 22 of a bell-shaped flange 23, the diameter of which at the perimeter of the larger: end 24 is substantially equal to the diameter of the bore of the port 13. This flange is perforated, the number of small openings 25 preferably about one-sixteenth of an inch in diameter and arranged as closely together as 10 is fully seated, so that the greatest possible space is provided between adjacent faces of the valve and flange in which the incoming fuel, separated into small streams during its '16 of the valve. This stem operates within passage through the openings 25, may again become homogeneous before entering the cylinder. In addition to its function of breaking up the particles of fuel entering the engine, this valve further acts to steady and prevent undue vibration of the valve, so that the valve will be much more apt to seat properly. Passage of foreign matter to the cylinders will, of course, be prevented by the screen and the screen itself will be kept clean of such foreign matter, due to the jarring action to which it is subjected.

stem passin centrally through the port, a

bell-shaped ody carried upon the stem at a point spaced from the valve, the stem assin through the longitudinal center 0 the y, said body having a lip extended laterally forming a flat annular portion disposed in a plane arallel with the plane of the valve and spaces therefrom, the diameter of the annular portion being substantially equal to the diameter of the port, the margin of the annular portion being spaced from the valve for a distance substantially equal to the vertical depth of the port whereby the lip ofthe body is received in the port when. the valve is closed and the valve and body are fixed with relation to each other, said body being pro- Vided with a plurality of relatively small closely spaced apertures.

In testimony whereof I hereunto aflix my signature.
