UNITED STATES HARRY E. DAVIS, OF JERSEY CITY, NEW JERSEY.
DEVICE FOR SPRAYING HYDROCARBON FUEL.
Application filed June 18, 1925. Serial N0. 37,967.
My invention relates to devices for spraying hydrocarbon fuel and while it is particularly adapted for use in connection with internal combustion engines, it can nevertheless be employed with facility and advantage in other instances and with other apparatus where the spraying of heavy hydrocarbon fuel for ignition is necessary.
In carrying my invention into practice it has been my purpose to provide a device of this character wherein all the openings or passages through which the fuel is fed, are entirely defined by opposed surfaces of abutting separable members, so that when said members are separated such passages are laid open for easy and rapid cleaning; this in contradistinction from devices of the same general nature in which the fuel passages are bored directly through material and must be cleaned with an instrument of a type likely to be broken off in the passage with the result that the latter is closed and the spraying device thereby rendered useless.
In the drawings chosen to illustrate my invention, the scope whereof is set forth in the claims:
Figure 1 is a bottom view of a hydrocarbon fuel spraying device embodying my invention;
Figure 2, a fragmental elevation showing the lower end of the spraying device disclosed in Figure 1, said device being shown mounted in the wall of the combustion chamber of an internal combustion engine, and
Figure 3, a vertical section of substantially what is shown in Figure 2.
Referring to the drawing my invention is shown as comprising a tubular member 10 having a reduced lower end 11 provided with external threads 12. Thebore of the member 10 is contracted at 13 to form a tapered valve seat 14 against which a suitable fuel timing valve 15 is adapted to seat. The diameter of the stem of valve 15 is less than the diameter of the larger portion of the, bore of the member 10 to provide a fuel passage 16 whereby fuel may flow to the contracted portion 13 when said valve is open. The extreme lower end of the bore of member 10 is flared to form a valve seat 17 against which seats a correspondingly shaped plu 18 having a stem 19 enlarged at its outer end as at 20, said enlargement fitting somewhat snugly in the contracted portion 13 of the bore of member 10 and having longitudinal grooves 21 therein to permit flow of fuel to the plug 18. The surface of the plug 18 which contacts with the seat surface 17 is provided with a plurality of radial grooves 22 which coact with the surface 17 to form fuel passages extending from the contracted bore portion-13 to the exterior of both the'member 10 and plug 18. \Vhile the plug 18 is detachable from the member 10 it is normally held immovable against the seat 17 during operation of the device and in the form of my invention illustrated this is accomplished by a cage cap 23 engaged on the threads 12. It will be noted, however, that the specific means for holding the plug 18 immovable against the seat 17 is not material to my invention and therefore any other suitable means for that purpose other than that specifically disclosed may be employed without departing from the scope of my invention.
From the foregoing it will be apparent that in the event the passages formed by the grooves 22 and valve seat surface 17 become foul they may be cleared and cleaned with facility and ease by simply removing cap 23 and plug 18; when the grooyes 22 and also surface 17 can be readily cleared of deposits. It will also be noted that by reason of the contacting surfaces of the plug 18 and member 10 such surfaces may be easily ground in the well known manner and a non-leakable engagement of the member and valve between the grooves 22, insured. For the purpose of conveniently rotating the lug 18 in such grinding operation I provi e'the latter with a groove 24 for the reception of a suitable operating tool such as a screw driver.
I claim:
1. In a device for spraying hydrocarbon fuel, a tubular member, an imperforate plug. loosely seated against one end of the. memher across the bore thereof, one of the abutting surfaces of the member and plug having grooves coaoting with the other surface to provide fuel delivery passages extending from the bore of said member to the exterior of both the member and lug, and a cage cap connected to the mem er and operating against the outer end of the plug to pressthe latter against its seat, said cage cap having an opening therein through which a-tool is engageable with the plug to move the latter and effect grinding of the contacting surfaces of'the plug and member.
2. In a device for spraying hydrocarbon fuel, a tubular member, an imperforate plug loosely seated against one end of the member ground joint between contacting surfaces of said plug and member, means permitting flow of fuel by said stem to said passages, and means for holding said plug against its seat.
3. In a device for spraying hydrocarbon fuel, a tubular member, an imperforate plug loosely seated against one end of themember across the bore thereof, one of the abutting surfaces of the member and plug having grooves coacting with the other surfaces to provide fuel delivery passages extending from the bore of said member to the exterior of both member and plug, a stem on said plug fitting snugly in the bore of said tubular h member and effective as a guide when grinding the plug against its seat toprovide a ground joint between contacting surfaces of, said plug and member, said stem having grooves formed therein permitting flow of fuel by said stem to said passages, and means for holding said plug against its seat.
4. In a device for spraying hydrocarbon.
fuel, a tubular member, an imperforate plug loosely seated against one end of the member I across the bore thereof, one of the abutting surfaces of the member and plug having signature grooves coacting with the other 'surface to provide fuel delivery passages extending from the bore of said member to the exterior of both the member and plug, a stem on said plugjitting snugly in the bore ,of said tubular member and effective as a guide when grinding the plug against its seat to provide a ground joint between contacting surfaces of said plug and member, said stem having a CIICUIIISCUbIIIg groove ad acent the inner end of the plug and further having longitudinal groovesextending from the outer end of the stem to said circumscribing groove whereby fuel may flow by said stem to said passages, and means for holdingsaid plug against its seat 5. In a device forspraying hydrocarbon fuel, a tubular member, an imperforate plug loosely seated against one end of the member across the bore thereof, one of the abutting surfaces of the member and plug having grooves coacting with rthe other surface to provide fuel delivery passages extending from the bore of said member to the exterior of both the member and plug, guiding means for maintaihing'the plug in axial alinement with the seat whereby said plug may be ground against its seat to provide a ground joint between contacting surfaces of said plug and member, and means for holding said plug against its seat.
