PAUL VIE'I, OF BILL ANCOUBIT, FRANCE. AUTOMATIC STARTING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
Application filed February 6, 1926, Serial No. 86,640, and in France June 15, 1825.
My invention relates to an automatic starting device for internal combustion engines which is characterized by the fact that 1ts several operative elements are grouped in a particular manner. The resulting apparatus essentially comprises a suction and discharge pump for gasoline or other liquid fuel which serves to facilitate the starting of internal,
combustion engines, as well as a device for the carburation of the air by the gasoline or like fuel whereb the engine may be started, the air to be car uretted being preliminarily compressed either by a hand or motor operated pump, or supplied from a compressed air tank.
My invention consists equally in the employment of two different pressures in place of one and of two spraying nozzles instead of one for effecting the formation and con veyance of the combustible mixture for the starting of internal combustlon engines, the two pressures being utilized throu h the agency of a special device, as hereinafter more particularly described.
In the accompanying drawings:
The Figures 1 to 7 are diagrammatic sec- I tional views of the operative elements of two embodiments of the lnvention.
Fig. 1 is a sectional view of a group of elements constituting an apparatus accordi to the invention.
Figs. 2, 3 and 4 are cross sections of the cock plug.
Figs. 5 and 6 are sectional vlews of a modified form of construction in which the several elements are differently disposed.
Fig. 7 is a sectional view of a modified form of the cock shown in Fig. 1.
Fig. 8 is a section of a comp ete apparatus according to the invention.
Figs. 9 and 10 are longitudinal sections of the plug keys of the valve.
Figs. 11, 11, 11 11 12, 12, 12 12 13, 13', 13 and 13 are transverse sections of the valve shown in Fig. 8 taken along the lines a-a,' bb, c0, 0'-c',
Referring to Figs. 1, 2, 3, 4, and 7, the apparatus comprises the hand-operated piston 1 withdrawing from the cylinder 2 the gasoline which is supplied through theinlet conduit 3 and discharging it throu h the outlet conduit 4 leading to the cylin ers or the suction collector of the engine. The carburete-r 5 is supplied from the cylinder 2, and the air thus carburetted proceeds directly to the engine valve gear through the outlet 6. Compressed air is sup lied through the conduit 8, and can be broug t to the upper part of the recipient 2, through the hand-operated valve 7. The whole apparatus is operated by combining the action of the compressed air controlled by the valve 7, and of the fuel feed ump, and of the cock plug 9, and three di erent positions are thus afforded for the fuel feed, as follows. 1.: Withdrawal of the gasoline. 2: Discharge of the gasoline. 3: Carburation.
These operations are performed as fol lows:
For the fuel feed, the plug of the cock 9 1s turned so as to connect the conduit 3 with the conduit 11 through the hole 10 (Fig. 3). By raising the piston l which is made tight .by suitable packing, the gasoline will enter the cylinder 2.
The cock is then turned so as to connect 4 with 11 through the hole 14 of the cock plug (Fig. 4), and when the piston 1 is pressed down, the gasoline will be discharged into the engine. This can be carried out in one or more like operations, and finally the cylinder or recipient 2 is filled by raising the piston 1 to the maximum.
The operation of the cock may be simplified by placing a ball valve 10', 14".in the respective conduits 3 and 4 which will in this case be connected at the same time with the conduit 11 (Fig. 7).
For thecarburation, the said cock is turned 1 so as to connect the conduit 11 with the horizontal carburetor, and the conduit 12 with the valve 7, through the respective holes 15 and 16 of the cock 9 (Fig. 2).
By pressing upon the knob of the valve 7, the compressed air is admitted into the chamber 2 and presses upon the liquid, thus causing the latter, to flow into the sprayer 5 of the carbureter, in which it is sprayed by means of a stream of air supplied through the conduit 13. This carburetted air is supplied to the engine, or to the valve gear, throughthe conduit 6. During this operation the piston 1 which is provided with a tapered internal'head, will form a valve cooperating with a seat formed in the said chamber, and this arrangement, combined with the packing, will make the device fiuidtight under approved conditions, by the action of the pressure itself.
It will be noted that the said cock will afford three positions for the discharge, i. e., first for the supply of gasoline and air to the cylinder; second for the supply of gasoline and air to the admission conduits; third for the supply of gasoline to the admission conduits. Due to its functions, the said cock forms one of the features of the invention.
Figs. 5 and show a modification of the apparatus shown in Fig. 1; herein the carbureter is vertical and the several parts are difierently arra'nged, but the parts differ from those shown in Fig. 1 only by their relative disposition, and the same numerals are employed. for similar parts, these being however shown as 5', 6' and the like.
The essential differences are as follows:
The cock is now perpendicular to the axis of the cylinder 2 instead of parallel thereto as in Fig. 1, so that the carbure'ter 5 Will now be vertical instead of horizontal. The valve device 7 remains parallel to the axis of the cylinder 2, but is now situated below the said cock instead of above it as in Fig. 1.
Since the functioning is quite the same as i for the apparatus shown in Fig. 1 it will not be necessary to further describe the several operations.
Obviously, the several elements of the carbureter such as the inlet and outlet for the carburetted air and the inlet for the compressed air may be given any suitable position, horizontal, vertical or oblique 1n the two apparatus above mentioned, w thoutpleparting from the principle of the inventlon. In like manner I may provide for the supply of compressed air and gasoline to the engine inlets by simply operating the hand-controlled valve.
Referring now to Figs. 8, 9 and 10 the apparatus comprises a piston 21, adapted to be actuated manually in such a way as to suck into a chamber 22 the liquid fuel which it takes up at an admission conduit 23 and to forcesaid liquid fuel by pressure through a tube 26 leadin towards the cylinders or to the suction co ector of the engine to be started. A. spraying nozzle 27 draws up the liquid fuel which passes then into a second spraying nozzle 28, then into an air conduit, whence it proceeds to the engine in the form of carburetted air. A valve 24 is provided which renders it possible to put a conduit 31, connected to air reservoir of air under pressure into communication with the conduits 32 and 33. These conduits 32 and 33 are of different cross sections and thus give rise to a difference of pressure between the low pressure air which comes through 32 around the spraying nozzle 28 and the high pressure air Which comes through 33 around the spraying nozzle 27. Regulating screws 34; and 35 renders it possible to carry out the following operations.
1. Suction of liquid fuel. 2. Forcing the liquid fuel by pressure into the admission-conduits of the engine which is to be started.
3. Production and compression of the carburetted mixture in the running position of the apparatus.
' The said operations are carried out as follows:
a. Suction.The plug key of the valve 25 is set in such manner as to establish communication between the orifice 23 and the conduits 29 and 30. The piston 21 is then raised, thus causing the liquid fuel to be sucked)into the chamber 22. The plug key of the valve is then turned in such manner as to establish communication between 26 and the conduits 29 and 30. The piston 21 is then depressed, whereby the liquid fuel is forced by pressure. into 26 and from there into the cylinders ofthe engine which is to be started.
b. ztunm'ng position 01' carbumtz'om -The preliminary operation is the filling of the chamber 22 which is effected in the manner which has just been described. The key of the valve 25 is then set in the position'shown in Fig. 8, so as to establish communication between the conduit 30 and the spraying nozzle 27. The plug key of the valve in its four positions as illustrated in the sections a a, b b, c '0 and c c renders it possible fon the purpose of carburation to establish the communication of31 with 32, 31 with 33 or 31 with 32 and 33 simultaneously. In the fourth position, viz, the stopping position, the communication'of 31 with 32 and 33 is entirely shut OK, but these conduits are put inconnection withthe outer air in order to relieve the pressure in the interior of the apparatus entirely.
When the valve 24 is in the position in which 31 and 33 communicate, the air passes in around the spraying nozzle 27 and acts on the level of the liquid fuel in the chamber through the medium of the conduit 36. The
admission of the liquid fuel takes place at If desired the valve 25 may be omitted and replaced by ball valves. The conduits of the key 24 which serve to put the apparatus when in the stopping position into communication with the atmosphere, may likewise be omitted without detracting from the satisfactory working of the apparatus as a whole.
The arrangement described above are applicable to any relative position of the members of the apparatus, for instance they may be vertical, horizontal. or oblique, the annexed figures only showing one method of carrying the invention into effect. It is understood that variations of details may be made without departing from the scope of the invention. It may also be mentioned that the feeding of the chamber attached to the apparatus may be effected in the manner. described by the aid of a little hand pump or in any other manner, even, for example, by gravity.
