PETROLEUM-ENGINE.
Specification of Letters Patent.
Patented Oct. 15, 1907.
Application filed November 5,1906. Serial Nd. 2,070.
To all whom it mayroncm:
Be it knownuhat I, ROBERT OWEN ALLsoP, a subject of the King of Great Britain and Ireland, residing at London, England, have invented Improvements in Petroleum-Engines, of which the following a specification."
The object of this invention is to provide an improved form of,'and method of constructing, the fuel inlet valve for petroleum engines having a fuel vapor pump such as are described in the specification of Letters Patent No. 725191 dated 14 April, 1903,-but/the invention is also useful in connection with other suitable types of internal combustion engine. I
Usually in petroleum engines having a fuel vapor lamp the fuel has been admitted through 'a single hole in the seating of the pump inlet valve.
According to this invention the fuel is admitted through a fine passage at more than one point in the valve seating. The valve is made with more: than one hole in the seating and the valve box is specially constructed so that the said holes may be easily made of any degree of fineness; as an alternative, a continuous fine groove or slit may be formed in the seating in place of the holes or isolating channels.
This invention I find by trial constitutes a very great improvement in engines of the type referred to. The objectionto having one hole only is that, if this single hole be very fine, insui'hcient fuel passes, while, if large, the fuel is ineffectually atomized, and a large portion enters the pump in liquid form.
I preferably carry out my invention in the following n1anneri-I make the pump fuel inlet valve box in two parts, suitably secured orbolted together. The
line of junction between the two parts cuts the valve' seating preferably on the center of the seating andpreferably at right angles to such seating. The two jointing places are accurately and closely fitted together preferably by'grinding. In the joint face thus formed I turn a small groove or channel; I suitably connect this groove to the petroleum supply. From the said groove I form, in the joint faces, suitable small grooves or cuts of suitable number, which, when' the joint faces of the valve box are secured together, form fine holes in the seating suitable to produce, by the inriish of air through suitable passages, perfect atomization of the fuel. These holes are stopped by the valve when held up to its seating by its spring, and the fuel supply automatically ceases when the engine steps. In place of the fine grooves, one joint face may be slightly turned down so as to leave a fine continuous slit for the fuel to pass, but I preferably employ the isolated grooves, which, in effect, form fine holes.
I control the fuel supply to my improved valve,
either by'a suitable needle valve, when I wish to employ simple pressure or gravity feed, or by a suitable float feed if I wish to maintain a vapor supply that may be 1 equal or approximately equal, per piston stroke independent of the speed of the engine; I suitably connect the float, feed to the valve, preferably by making the float chamber and part of valve-box as one casting. v v
The accompanying-illustrative drawings show my in-.
vention and the manner of carrying out? the improvements. 1 V s Figure 1 is an elevation of the complete valve. Fig. 2 a plan, Fig. 3 a section and Fig. 4 a plan of lower. part of valve casing, all of the preferred construction; Fig.
5 is a part sectional elevation similar to Fig. 2-of a modification. v I
A is a casting forming theQlower part of the valve box; B is the upper portion of the valve box; and C is a nut or union cap drawing the two parts of the valve" together; D' is the valve held to its seating by a suitable spring; E is the entry for petroleum, being a tapped hole into which can be screwed a controlling needle valve. As shown, the junction line of the upper and lower. parts of the valve box occurs in the center of the valve seating. The lower valve box part is bored as a guide for the parallel portion of the upper valve box part.
F, F are holes for the admission of air.- I
A hole G is-drilled to meet the petroleum entry an is continued until it meets the junction faces of the two parts of the valve seating H and a channel J is turned in one or the other or in both of the valve box faces. In Fig. 3 it is shown as turned in the part A.
The hole, G, being plugged as shown, the petroleum can find its way from the entry to. {the circular turned channel. Fine channels or grooves K, are formedbetween the circular channel and the valve seating either in one or the other or partly in both parts of the box but shown inFig. 3 as foi nied in the part A. Iliese grooves are preferably made with a fine three-cornered file, or they may be formed witha graver or other suitable tool by hand or by machine. The two parts of the valve box being screwed together bythe cap, the petroleum can now find its way through the grooves which, when the parts of the valve are put together become virtually fine holes. When the valve is lifted offits seating by the suction of the pump'piston the petroleum is sprayed-by the air entering holes F-on to the hot surface of a vaporizer which for example may be exhaust-heated and located over the fuel vapor pump of the engine. By this construction the advantage of very fine passages as regards effective atomization of the formed in the seating by turning down the joint face of the upper or lower part of the valve as for instanci" shown in Fig. 5 where said groove or slit as well as the turned channel J are formed in the part B.
What I claim is:-
i l. in an internal combustion engine. a fuel valve comprising a valve box part having a valve seat portion, another valve box part provided with the other seat portion. co-acting junction faces between the valve box parts, grooves in one of such faces lcadingio the valveseat. a channel communicating with said grooves. and a fuel supplvpassage connected with-the channel.
2. In an internal combustion engine, a fuel valve comprising a valve box part having,' a valvc seat portion. another valve box part provided with the other seat portion. co-acizing junction faces between the valve box parts said junction surfaces extending to the valve seating at right angles thereto, an annular groove formed in one junction face and anumbcr ot notches formed in either junction face communicating with'the valve seating and the annular groove and a passage for the supply of fuel to-the latter.
3. in an internal combustion engine. a fuel valve comprising a valve box part having a valve seat portion, auothcr valve box part provided with the other seat portion. co-acting junction faces bctwccn the valve box parts, said junction faces extending to the valve scatingat right anglcs thereto. an annular channel formed in one junction face and a number of notches formed in either junction face communicating with the valve seating and the annular ,qroovix a passage leading from the channel to-the iuel supp y and means or securing-the two portions of the valve box together.
4. in an internal combustion engine, a fuel valve comprising a valve box part havlngla valve seat. portion an- .other valve box part provided with the other seat portion, -co-actiug junction faces between the valve box parts, said junction faces extending to the seating at right angles thereto, a union'nut for drawing said parts into close contact and means whereby fuel can be introduced through the .valve seat uniformly therearound.
In an internal combustion engine. a fuel valvo comprising a valve box part having a valve seat portion, a'
ground face at right angles to the seat portion. an annular channel in said taco passages radiating from sucll chauncl andwxicnding through the valve seat portion and a passage leading from the channel to the fuel supply. a valve box part fitting within the first named part. a ground face and valve seat portion co-acting with the face and valve seat portion aforesaid, a union nut for maintaining such faces in contact. a vah'e seated on both seat portions and ports for supplying air to one side of the valve.
