Description
Dec. 19, 1933. H MUSE;v 1,940,171
NOZZLE Filed June l, 1935 Patented Dec. 19, 1933 UNITED STATES PATENT QFFICE This invention relates to burner tips or nozzles of the atomizer type, and is particularly applicable to nozzles for oil burners in which the oil is delivered to the atomizer under high pressure.
These nozzles are subjected to high heat, and one of the objects of the present invention is to avoid any errors of position of the various parts due to warping or other changes incident to the effects of heat. I,
For example in my pending application Serial No. 599,022 there is disclosed a nozzle with an enclosed stem terminating in a distributor head which must be very precisely located' with respect to the setting containing the spray oriflce, which orifice is of very small dimensions and is usually made in a diamond or similar'hard mineral insert. 'I'he small dimensions require for full efficiency that the parts shall be exactly positioned.
Also, such screw stems commonly have some slight yeccentric motion which results in misalinement. This is avoided by the present invention which permits the distributor head to nd its correct seat regardless of any eccentricity in the stem or screw pin.
By means of the present invention the exact relation between the distributor and the orifice is maintained under all conditions.
A further object of the invention is to generally improve and simplify the construction of such nozzles.
One form of the invention is illustrated in the accompanying drawing in which Fig. 1 is a side elevation of the nozzle. Fig. 2 is a longitudinal section. Fig. 3 is a perspective of the stem by which adjustment of the distributor head is effected. Figs. 4 and 5 are front and side views of the distributor head. Fig. 6 is a sectional view enlarged, of the setting or orifice member.
In thel drawing, 8 indicates the body of the nozzle having an orifice 81 at its front end preferably at the apex of a flaring recess 82 at the front end of the body.
- Seated at a close or force fit in the front end of the bore of the body is a setting member 11 in which is preferably cast or set a perforated diamond or hard stone 12 which is positioned directly behind the hole 81.` The rear face of the memberv 11 is beveled or inclined as indicated at 13 to an orifice 14 which leads to the hole in the diamond 12, this orifice or recess forming what may be described as a swirling chamber in which the oil forced through under high pressure has alswirlingV action to produce an atomizing jet. Resting against the rear face of the setting member 11 is a "oating distributor head or disk 10 the loweror front face of which is beveled as indicated at 15 to fit the face 13, and said face 15 is provided with a number of o0 tangential grooves 16 which form ducts to direct the er1 to the swirling chamber referred to, at
such an angle as to produce the described result.
This distributor head or disk is machined to very close dimensions so that when dropped in and pressed to its seat its conical face will fit very precisely against the setting member.
Behind the distributor head 10 is a stem 9 terminating in a at face 90 which bears against the rear face of the head 10. The advantage of this separate or detached construction of the head and stem is that under all conditions the head 10 may seat itself uniformly, around its complete front surface, against the face 13 of the setting member, irrespective of any variation in the exact axial line of the stem. That is to say, when the stem is screwed in the head will be pressed exactly to its seat or proper position. The stem is enlarged and threaded as at 91 to screw into the interior threads 83 in the body, and the enlarged part has a number of longitudinal grooves 92 to permit the flow of oil from the pipe line or supply into which the nozzle is set. For this purpose the rear end of the nozzle is threaded as at 84 and has a hexagonal portion 35 to receive a wrench. The stem 9 has a kerf 93 in its rear end to receive a screwdriver for its adjustment.
By the means described a very exact and precise relation of the parts can be maintained at all times, and furthermore should the distributor head 10 become eroded a new one can be put in without renewing the stem.
I claim:
1. An atomizing nozzle comprising a body having therein a fixed member with a tapered swirling chamber therein and an ejection orifice and a tapered surface to the rear of the swirling chamber, a distributor in the body, having a self-centering tapered face corresponding in form to the said tapered surface fitting against said member and provided with whirl producing grooves leading to said chamber, and a screw stem in the body, behind the distributor, pressing against but detached therefrom, the distributor being free to have lateral play with respect to the stem.
2. An atomizing nozzle comprising a body, a member iltting therein and having a swirling chamber and a conical seating surface behind said chamber, a head having a conical face fitting against and conforming to said surface and provided with grooves leading to said chamber, and a screw stem in the body, pressing against said head but detached therefrom the head being free to have lateralvplay with respect to the stem, whereby the head centers itself against said conical surface irrespective of the axial alinement of the stem.
