(o1. 137-153) This invention is an apparatus for controlling supplied to the chamber I by the pump II will the supply of fuel oil to a burner. not pass therethrough. The outlet opening IS One of the objects of the invention is to prois provided with a by-pass pipe 3|, which leads vide simple and' ecient means for maintaining from the chamber I5' to the supply pipe I2 in 5 a constant volume flow of oil to the burner atomsuch lmanner as to by-Dass the pump I I, said izer, irrespective of the viscosity or temperature pipe 3| joining the pipe I2 between the pump and -of the oil. A further object is to remove from the tank.

Figure 5 is a to move upwardly through the port 26 into the diagrammatic view, partly in section, illustrating pipe 30 and will thereby be returned to the tank 25 a modified form of apparatus. ii). At the same time, oil will ow through the 25 Referring to the drawings, IIJ designates a port 21 into outlet |.8 and from thence through storage tank, and an oil pump of the type pipe 29 to the burner. Inasmuch as the ports commonly employed on oil burners. Leading thus far described-are not of suiiicient combined from the tank I0 is an outlet pipe I2, which at area to carry the entire flow of oil, a part of the 30 its delivery end is connected with theA pump II, oil will also flow out of the port 28 and outlet 30 which is provided with a discharge pipe I3. opening I9 through the by-pass pipe 3| and back In "the form of the inventionillustrated irLFigs; to the pump, so that the 'by-pass pipe provides a l, 2 and 3, the pipe I3 discharges into the casing means for maintaining a constant supply of oil I4, which casing is provided with a chamber I5 suicient to maintain the feed demands of -the having an inlet port I6 and three outlet ports burner supply pipe 29. 35
I 1, I8 and I9. Located within the chamber I5 The piston 2D is rotatively mounted within the is a movable piston 20, which is provided with a easing I4 for the purpose of adjusting thevolume flange 2| normally pressed toward a'shoulder 22 of iiow through the respective outlets. 'I'his of the casing by means of a spring 23. The tenrotative adjustment may be effected in any de- 40 sion of the spring may be regulated by an adjustsired manner, but preferably by. means of an ec- 40 ing screw 24 bearing against the abutment 25, as centric pin 32 carried by a rotatively mounted clearly shown in Figs. 1 and 2. The flange 2| is shaft 33, provided with a handle 34 located opprovided with three slots or openings therein inposite a quadrant 35. It will be observed that dicated at 26, 21 and 28, respectively, so posi.- bymaintaining a continuous and definite quan- .tionedas to register with the outlets I'I, I8 and tity of oil from pump through the pipe I3, the 45 I9, respectively. piston valve 20 will automatically'move against Leading from the outlet I'I is a return pipe 30, the tension of its spring until the three oil flow which discharges into the tank Ill. It will be ports 26, 21 and 28 open to the proper extent to noted that the slot or orifice 26 is of considerable allow a. definite amount of oil to pass under a less area than the cross-sectional area of the given pressure setting of the spring. Assuming 50 conduit 30. The oil feed pipe 29 for the burner the ports 26, 2'I and 28 to be of equal Width, the' leads from the outlet opening I8, and may be quantity of fuel passing through the port 21 and connected with the burner in any suitable manthrough the pipe 29 to the burner atomizer ner not shown, it being noted however, that the' would be one-third of the quantity of oil supplied outlet 2'I is of such small area that all of the oil* by pump .II through pipe I3. The same will be 55 ypassing through the chamber into the pipe 28.
It has been previously pointed out that by. reason of the oil flow port 28, a portion of the oil furnished by the pump will pass through the pipe 3I and to the suction side of the pump through the T 38, and this considerable portion of the oil from which the air has been removed will furnish a part of the oil drawn by the pump.
Thus, after the pump has been put into opera-l tion, only a portion of the oil required by the pump is drawn from the tank I I. In this manner, there is always sufficient oil to enable the pump to pass a constant volume through the pipe I3 to chamber I5. Having a constant quantlty of oil delivered to said chamber, the pistonv valve 28 will automatically compress the spring 23 and allow all of the oil furnished by the pump to distribute itself through the ports 26", 21 and 28 in accordance with the rotative setting of the piston valve. As the viscosity of the oil changes, the piston valve will automatically move to apoint that will open the ow ports 26, 21 and 28 to the proper extent.
In the form illustrated in Fig. 5, in'lieu of the casing I4 and the viscosity valve 20, the pipe I3 discharges into the casing I48l of an air separating device. Said casing is provided with an internal chamber having therein a cylindrical screen I*3L surrounding a branch I6'L of the outlet pipe, which branch: extends downwardly into the casing I 4 a substantial distance through the top thereof. It will be noted that the conduit I3 communicates with the bottom of said casing and that the return pipe 30 leads from the top of the casing I4". It will also be observed that the last-mentioned conduit communicates with the casing |43' through a coupling 31, which is provided with an orifice 38 of considerably less diameter than the diameter of the conduit. The 'outlet pipe I8* is connected with an 'oil feed pipe 39 of reduced diameter, which constitutes the oil feed to theburner atomizer. The pipes I6a and 39 are l connected by a" T 40, which is provided with a transverse wall 4| having a small orifice 42 of less diameter than the diameter of either of the pipes IIin or 39.
The by-pass pipe 3|B leads` from the T 4I) toliver the oil to the casing I4 through the bottom thereof. The passage of any oil through the screen |58 yresults in the elimination of air bubbles therefrom, and the oil from which the air has been removed .passes out of the chamber through the pipe I6, a portion of the oil also passing out into the conduit 30 and back to the tank, the stream of oil passing out through the conduit 30 carrying with it such air as has been separated from the oil, which passes through the screen I5. The by-pass pipe 3|'L acts in the same manner as the by-pass pipe 3| illustrated in Fig.v 1. y
'I'he advantages of the invention will be readily understood by those skilled in the art'to which it belongs. means of'either form of the invention as described, a constant volume oil flow tothe burner atomizer is maintained, irrespective of the viscosity or the temperature of the oil.` A further important advantage is that the air is emciently separated from the oil in the suction line in such manner as to prevent it from being delivered to the burner atomizer, and the trapped air is conducted out of the stream and delivered into the storage tank.
Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its usa-what is claimed is:
Apparatus for controlling the flow of fuel oil to a burner comprising a casing having a central bore therein, an inlet opening at one end of saidA bore through which fuel oil under pressure may be admitted to said bore and a. plurality of outlet openings spaced about the periphery of said bore through which said fuel oil may be discharged from said bore, a piston, slidable under the influence of the pressure of the fuel oil entering said inlet opening axially of said bore, having portions thereof covering and normally closing said outlet openings and provided with slots registrable' with said outlet openings when said piston ismoved to gradually uncover said openings,- said piston having a recess in the periphery thereof, resilient means for resisting the movement of said piston axially of said bore, a shaft journaled in said casing, said shaft having secured at one end thereof a pin axially offset with respect to the shaft axis and engaged in the recess of said piston, and means for rotating said shaft to move said pin in an orbital path about said shaft axis and impart rotary motion to said piston.
