To all whom 2l may Concern:

Be .it known that l, @aan A. laoiinsson, a subyect of the lling of Sweden, residing at Wellsville, in the county of Allegany and' State of New York, have invented certain new and useful 'improvements in litoinizers for Oil-Engines, of which. the ollovving'is a specification, reference being had to the accompanying drawings.

'lh-isiinvention' relates 'to internal combus tion oil engines and has torits. primary ob- .jectito increase the elllciencyl inoperation' and consequently the working energy developed 'in .engines of that type wherein an atoinized 'fuel is burned in the combustion chamber by the temperature of highlyconr .pressed air into which the luel is liberated.

lChe invention has for 'a lparticular item of improvement, a fuel atomi'zing valve of relatively simple construction, through the medium oi' which the liquid '.tuel is delivered in a very linely atomized state and under high pressure to tlie combustion chamber.

l also have in view the provision of an improved fuel atomieer possessing the above noted advantageous features and capable of utilizingl unretiied, hydrocarbon oils as fuel so that the operating cost will be relatively small, the several parts employed being simple in their construction, not liable to get vout of order, and highly positive and reliable in practicaioperation. y

lilith the above and other objects in view,

. my invention consists in the novel features ot lol i i llig. 2 is 1a'. sect'on talren on the line 2-2 construction, l. combination. and arrangement oit parts to 'be hereinafter more fully described, claimed and illustrated inthe ac coinpanying drawings, in which,

Figure l is a longitudinal section of the fuel atomizing valve;

of rig. i.

ln oil engines of that type wherein the fuel vcharge is fired byv the heat of compres sion clean, atmospheric air is drawn by suction linto vthe engine cylinder in the niovenient of the piston in one direction, the valve y 2 5 beingpositively opened. Un the reverse stroke of the piston, this air is very highly compressed `Within the relatively restricted dimensions vof the combustion chamber. rllliis pressure is suflicient to increase the temperature ol the air-to such a degree that it Will instantly ignite the.inelyeoinrm-l which longitudinally bored,.as at 35. The

opposite ends of this bore 35 are enlarged and threaded, and a detachable nipple 36 is engaged in one of said threaded ends of the 'bore and connected by means of the pipe 37 to the air compressor. The inner end of the nipple is spaced from'tlie reduced, central portion or the bore 35 to afford a relatively large collecting chamber 38- between the nipple and the valve head 39 formed upon the reduced end 41 of the longitudinally niovable valve rod 40. rlhis valve head 39 is Patented Feb. 5, wie, reprimida aies november as, inra .anni no. lesser. l

normally `in tight engagement upon the,

valve seat 42 and disposed in spaced relation to the inner end of .the nipple 36. ln the other threaded end of the borel 35, the cnterioi'ly threaded endoi. a sleeve 43 is engaged, and Within the bore of said sleeve the valve rod 40 is inovably disposed, said rod having spaced .packing vgrooves 44. to eflectually prevent the leakage Aof the-,air or luel around the valve rod. rlhe` sleeve and valverod are inclosed within an outer casing 45 which is bolted or otherwise rigidlyiined at one of its ends to the body 34, id body in turn being suitably secured to' 'face of the cylinder head 17. The casing' 45 is ends with an internal flange 46 affording a support for the endet the sleeve 43. A

cylindrical head 47 is slidably engaged in vided with a reduced, threadedentensionf upon which a nut 51and sleeve areengaged, said nut 'being interposed 'between the sleeve andthe end et th'eboes y provided intermediate of its l es@ edwiihin The body 34 is also centrally formed with an oil receiving chamber in communication with the center of the bore 35. A sectional valve casing 5l is fitted within the body 3l, one of said sections having orifices 55 through which the oil is forced under pressure into the chamber 53. The other valve section constitutes a cage for the ball check valve .5G which prevents hackfiovv of the oil through the bore of the nipple 57 to which the supply pipe 5S, extending from the fuel pump, is connected.

A laterally extending, cylindrical arm 59 is integrally formed with the body 34 and is adapted to be fitted within the central opening` in the front side of the detachable cylinder head which is in communication with the combustion chamber 1S. Ifhis arm is longitudinally bored, as at GO, the axis of said bore being out of coinciding relation with the longitudinal axis of the valve rod 40. T he bore 60, at its inner end, terminatos in spaced-relation to the bore 35 ex tending at right angles thereto, and within this inner end of the bore GO a flanged disk 61 is seated, lli. sleeve 6:2` is fitted Within vthe bore 60 and has a reduced end 63 engaged Within the annular flange on the disk (51. This sleeve 62 has a central, longitudinally extending mixing chamber (il gradually flaring or increasing in diameter to the outer end of said sleeve. rl`he face of the disk (il next adjacent to the reduced end of the sleeve (32., has an annular recess 65 therein of greater diameter than the end of the chamber 't5-l, and a plurality of oblique fuel inlets 66 lead from this recess to an annular groove or channel 6? formed in. the periphery of the disk 61. This disk has an air inlet opening 68 which is in registering relation with an air passage 69 in the body 34 extending substantially .in'tangential relation to the bore 35 at the lower side thereof. A second orifice 70 permits the passage of oil from the collection chamber 53 into the fuel inlets 66 in the disk 61.` In order to conveniently clean the oil collection chamber and remove sediment therefrom, a Screw 71 is threaded'in the body 3land has a needle point 72- for engagement in the outer end of an orifice '73 communica-ting with said collection chamber in opposed re lation tothe orifice 70. downwardly inclined duct 74, extending through the body 34, is in communication with 'the outer end of the orifice 73.

For the reason to be presently related, the air inlet opening 68 in the disk 60 and the air passage G9 are of somewhat less diameter than the inner end of the mixing chamber 64 through the sleeve A spray nozzle 75 is threaded in the end of the arm 59 and has a central passage or bore 76 of relatively small diameter flaring at one end, as at 7'?, to. approximately the same. diameter as the outer end of the mixing chamber 64. The

end face of this nozzle opposed to the combered, cylindrical boss 81. A rod 82 is slidably disposed through said chamber and has a. reduced portion extending through an openinglr in the endwall ofthe chambcrto which u diamctrically extending key 83 is fixed, The end face of the boss Slis grooved, as at 8l, to receive. the ends of this key. The rod 82 is provided with a slightly reduced-end portion vupon which an operating element 85 is suitably fixed.v In the present instance. l have shown this element as consisting of a conveniently shaped hand grasp having a sleeve snugly 4fitting within the chambercd boss S1. A vcoil spring 86, disposed within said chamber, acts against said sleeve and normally urges the rod 8:?l outwardly so that in one position of said rod, the ends of the key 83 will be held within the roove 8-1.

T ie other arinof the bell crank lever 78 extends forwardly and has a roller 87 suitably mounted thereon for engagement by a cam 88 fixed upon the cam shaft S9.

From the above descriptiony the operation of the fuel atomizing valve Will be clearly understood. The rod 82 must first be forced longitudinally against the action of the spring 813 to disengage the key 83 from the groove Si. The rod is then given a quarter turn so that the key will be held in its extended position with relation to the boss 81. Thus, in the rotation of the cam shaft, the bell crank lever 78 is actuated to intermit# tently shift the. valve rod 40 inwardly against the action of the spring` 49. It is to be remembered that the fuel is'being supplied during the operation of the engine, from the um under4 ressure, upwardly past the ba l va ve 56 an' into the collection chamber 53. The fuel pum delivers the fuel into chamber` 53 and'ori ces 70 and 73,

' the combined capacity of which is equal to pressure in the chamber 53 is subject to .the

variable pressures in the combustion-.chamber, and it is the purpose of the ball'` checkl valve 56 to restrict these' pressurestothe consequently, is not under pressure.` 4The` iimit ei seid cheminer emi Wiiieii direeiijgf communicate with the eemeusieu chamber.
