FUEL
Application led June 30, 1925, Serial No Thisinvention relates to a fuel valve for atomizing fuel by air pressure, such valve being applicable to Diesel motors in which `the valve is to be placed horizontally orinclined downwardly or upwardly.
Referring now to the accompanying drawings e Figure 1 is a sectional elevation of a fuel valve according to my invention;
Figure 2 is a perspective view on a scale of a detail of Figure 1, and p Y Figure 3 is a side elevation of a Vmodified constructional form ofthe detail shown in Figure 2.
According to the invention (Figures 1 3) a plurality of flat, angular or cupshaped shelves t are arranged in front of the valve seat, reckoned in the direction of the air current. 4 The inclination of the said shelves relatively to the inclination of the walls s from which they project, in the constructional forni represented, thesurface of a ring, corresponds to the inclination of the fuel valve relatively to a vertical plane. At the inner end of each shelf the wall s is provided with holes u, The fuel oil is squirted on to the shelves and the compressed air in the valve casing a vcarries it through the holes.l u and eventually through known atoinizing rings y and an atomizing cone .e
larger to the compartment immediately in front'of the valve seat n and from there through the atomizing ring 0 to the cylinder.
In order that the fuel oil may be squirted on to the shelves t it is fed under pressure through a channel p of the atomizing tube Z, in which the valve vspindle m is movable, to an annular cavity g having a series of holes r along its periphery. The circle of fuel oil jets squirted through these holes is then taken up by the shelves t of the ring s.
As some fuel oils will always run down from the shelves t, the atomizing tube Z is at its lower side shaped as a cup v fitted tightr ly in the valve casing and provided only with a perforation o: at its top through which the compressed air may pass from the valve casing le to the shelves t of the ring s. The cup e gathers the oil coming from the shelves t and the oil gathered in the cup will be carried away successively with thek compressed air. As already mentioned, one or more known atomizing rings u and a known atomizing cone e may be placed'behind the special atomizing ring .sf with the shelves t in the direction of the air current.
VALVE.
. 40,678, and in Denmark January 13,1925.
i A perspective view of the ring S is shown 1n kFigure k2. The inclination of the shelves t relatively to the surface of the ring depends, as already stated, on theposition vin which the fuel valve has to wor r. `When the shelves are flat, as shown in Figure 2, j care'must be taken that they are directed somewhat upwardly;
yFigurev 3 shows, in a modification, the.
atomizing ring'a, its shelves b having an angular cross section so that the fuel oil will settle in the angle as rshown at c.k
The holes u correspond with the holes'u of Figure 1 and the fuel oil projected on to the shelves b is carried away from the latter through the holes u by the compressed air, the arrows cl', e indicating theV direction of movement. The oil may pass'further through one or more atomizing rings of suitable form and the atomizingcone to the valve seat and finally into the cylinder.
Ther shape of the shelves t or b may be varied in many ways; e. g. they may be 'cupshaped. Care must only be taken that their shape and inclination is such that the fuel oil may rest fora while thereon.
