To all whom it may concern:
Be it known that I, GILBERT l/VRIGHT, a
citizen of the United States, residing at Felnam, 1n the county of fi estchester and State of New York, have invented new and useful Improvements in Electromagnetically-Op- Valves, or winch the following 1s a specification.
The present invention relates to valves ,dapted to be located "Jnduits for the coneyance fluid, t serve as the inlet and exhaust valves of steam engines,
internal combustion motors, and the like, anywhere that it and in fact be used is desirable to inter :pt and periodically permit, the flow of any liquid, gas, or
vapor. The purpose of the invention is to provide an electromagnetic means for operating such valves; the particular utility of such operating means in connection with the valve being that both the operating means and the valve may be contained in a closed chamber, whereby it becomes unnecessary to have any-part of the valve or its operating means pass through the wall of the conduit chamber in which the valve is contained,
' and the opportunity for leakage of fluid, and
the need for packing to prevent such leakage are avoided.
i i hile the invention is applicable generally to any of the uses comprised within the broad statement of uses hereinbefore set forth, it is particularly adapted and available for controlling the admission of fuel, and particularly liquid fuel, to an internal combustion motor, wherefore I have shown the purpose of illustrating the invention an embodiment of the same which is particularly designed to serve this use. It is to be distinctly understood, however, that this embodiment is so shown for the purpose of illustration only and without intent to indicate limitation of the invention to any specific mechanical form. in the drawings,
Figure 1 is a plan view of the e f an internal combustion motor having a valve and its controller, in which my invention is parti ularly comprised, applied thereto.
Fig. 2 is a sectional view of the combined apparatus taken on line 2-2 of Fig. 1.
Fig. 3 is a sectional view showing a modification of the armature.
I willdescribe in detail the specific embodiment here shown and then point out in I GILBERT WRIGHT, OF PELHAM, NE
Specification of Letters Patent.

Patented Nov. 5, 1918,
of an internal combustion motor into one head of which is screwed a nipple 12 on a case 13 to which is connected a detachable cover Through the center and of the case 13 end of which is exposed to the interior of the cylinder, and the outer end oi which is formed with a socket 16. into said socket, the walls of which are threaded, is screwed a plug 17 which l kewise has a socket or recess con i a1 through the bottom of which is an opening 19. From the recess 16 a passage 20 leads longitudinally through the core 15 and terminates in a valve the inner and of said core piece, which contains a valve 21 so formed as, when seated, to close the internal orifice of the passage 20. Said valve 21 is carried a stem which pass-cs through the core nipple P1668 15, through the plug 17, and carries on its end an armature 23 which is removably secured on said end. The spri 18 previously mentioned cenlined between the armature and the bottom of the plug 17 and presses constantly against said armature ten-din;- t :e 2-1 passage 20.
A pipe 2 1 is coupled by a' coupling 25 to a nipple 26 on the cover 141-, and through the latter there is a small passage 2'? opening into its interior. This passage 27, the space inclosed within the cover 14, the recess in the plug 1?, the hole 19 from the bottom of said recess, M13 o .l the passage 20, provide a continuous conduit from the pipe 2 1 into the interior of the cylinde l conduit controlled the valve 21.
The details of construction just described, although they are preferred for the purposes of the as: to w h the invention is here shown (as being applied, as being the simplest, most convenient, and most eflicient co struction which 1 have thus far devise r I not ebb i Q i A e vention, and 1 therefore do not llmlt my claim thereto. Various modifications in such details passes a core 15, the inner be guided by the nipple of the cover or by EtIIBXtGIlSlOIl of its upper end in the case, and the valve itself could readily be arranged to coact with the inlet to the case rather than with the outlet therefrom. And instead of securing the case to the cylinder by means of a nipple, the
latter could be omitted entirely and the case screwed directly to the. cylinder, or attached by external means such as bolts or studs. The essentials are simply that there must be a closed casing of some sort, suitable means of securing the same to a cylinder, pipe, or other connection with which the casing is joined, a valve member with its cooperating seat, an electromagnet, and an armature cooperating with the magnet and arranged to operate the valve. The armature itself may serve as a valve in some cases, as hereinafter pointed out, and then no other valve need be provided.
Inclosed within the case 13 and surrounding the core 15 is a magnet coil 28. The terminals 29 and 30 of this coil pass through the side of the case through bushings of insulating material. Preferably a gasket 31 is arranged so as to cover the end of the coil and is clamped between the case 13 and its cover 14, and also between the core 15 and a flange on the plug 17, the gasket being thus a fluid tight septum preventing access of the fluid to the coil or indeed to any part of the closed casing except the space which forms part of the conduit previously described.
I It will be understood that by reason of the gasket, which of course. is fluid tight at its inner and outer peripheries, the oil or other fluid is confined when the valve 21 is closed and is prevented from flowing anywhere except through the passage 20 into the cylinder 11 when the valve is open.
As the valve, coil, and the armature for the coil, which constitute the operating means for the valve, are all contained within a closed case, it can very easily be made absolutely fluid tight, there is no opportunity for the oil or other fluid to leak to the eX- terior of the conduit, and therefore no need to provide any sort of packing for the valve to prevent such leakage. Thus the valve may be made to operate more freely and easily than is possible where packing must be used, while the other inconveniences attendant upon a valve packing are avoided.
The gasket 31 is useful particularly to protect the coil 28 from whatever deleterious effects the oil or other fluid passing through the conduit might have on the coil if it were given access thereto. Where any such effects need not be considered the gasket may be omitted. and in such case the passages through which the leading-in wires to the coil pass would require to be sealed or otherwise made fluid tight in any well known, or other suitable manner.
by other means than-the core, as
When the device as hereinbefore described is applied for the purpose of admitting liquid fuel to an internal combustion engine, a timing. switch is provided to cause the, opening of the valve at the desired instants of time. Such switch comprises a stationary contact 32 and a movable contact 33; the
'former being connected with the terminal latter passes it. Shaft 34 is driven by the motor at the given rate of speed so as to cause the circuit to be closed at the required intervals. The complete circuit is shown in a diagrammatic manner in Fig. 2, wherein a battery 38 is shown, one pole of which is connected with the magnet coil terminal 29, and the opposite pole is connected by a wire 39 with the metal cylinder or other metallic part of the motor, through which the current is adapted to flow to the shaft 34 and thence to the switch contact 33. The battery 38 is merely typical of any source of electrical energy and may be taken as representing a generating machine or a sec- .ondary battery as well as a primary bat.
tery of any desired sort.
With the foregoing description in mind the operation of the valve may be readily understood, and it will be appreciated that whenever the switch contact 33 engages the contact 32, the armature 23 is attracted toward the pole of the coil, thereby opening the valve and allowing inflow of a quantity of liquid fuel. When the armature is made imperforate as shown in Fig. 2 it is adapted by itself to serve as a valve by coming in contact with the end of the plug 17 the comp'lemental surfaces of the plug and armature being then finished so as to make liquid-excluding contact. When used in the specific combination illustrated, the armature is a valve supplemental to the valve 21 and limits the quantity of liquid fuel injected into the cylinder at each operation. For other purposes the said armature'could be used alone as the valve, the valve 21 being then removed; or the armature can equally well be formed with apertures 10- as shown in Fig. 3 to permit passage of the fluid when it is brought against the plug 17 and the valve 21 is opened, then having no valve function whatever.
It will also be understood that various modifications in fornriand arrangement of the elements of the device may be made to adapt the same to the various uses which the invention is capable of serving. I claim within the scope of the protection here 130 the claims.
