OTAKAR PDHAJSK, OF WARREN, PENNSYLVANIA.
CONTROLLING DEVICE FOR INTERNAL-COMBUSTION ENGINES.
To all whom 'it may concern:
Be it known that I, OTAKAR PODHAJsK', subject of the Emperor of Austria-Hungary, residing at lVarren, in the county of W'arren and State of Pennsylvania, have invented new and useful Improvements in Controlling Devices for IntcrnaLCombustion Engines, of which the following is a specification. l
This invention relates to controlling devices for internal combustion engines, and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.
The controlling device is particularly adapted for use in connection with internal combustion engines using producer gas,
and in the'preferred construction, the con' trolling device is also supplied with connections for a different quality (ordinarily natural gas) than producer gas, so that with the same general Vmechanism either Gas may be used, and consequently the usefullness of the engine increased.
The invention is illustrated in the accompanying drawings as follows:
Figure 1 is a section on the line 1-1 in Figs. 2, 3 and 4. Fig. 2 is a bottom view of the controlling device, the portion of the cylinder which is connected being in section. Fig. 3 is a section 0n the line 3--3 in Fig. 1. Fig. 4 is asection on the line 4-4 in Fig. 1.
1 marks the inlet passage of the engine cylinder; 2 the main inlet valve controlling said passage; 3 a valve case or mixing chamber; 4: the valve seat in the case on which the main inlet valve operates. The valve case 3 is set into the opening 5 of the cylinder leading from they passage 1, and extends through a valve chest 6. The valve chest has the gas passage 7 and air passage 8. The valve case 6 is provided with the openings 9 leading from the passage 7 to the interior of the case, and the ports 10 leading from the air passage 8 to the interior of the case. The upper part of the case 3 which is connected with the gas passage 7 is connected-with the lower part of the samecase by an opening 11. This o ening, is controlled by a valve 12. A cylindrical valve 1-3 operates upon passages 10. The valve 13 is con- Specica'tion of Letters Patent. Application filed December 26, 1908. Serial No. 469,366.
nected with the valve `12 by the web or spider 13, and these valves are supported by the stem 14.-. The stem 14 extends from the main inlet valve 2 through the case 3.
It is provided with the head 15 at its outer end, and a spring 16 is tensioned between this head and case and tends to maintain the valve in a closed position. During a certain stroke of th'e engine, the main valve is open either by 4reason of the reduction of pressure `on the inner side of the valve or mechanism not shown, and this moves the stem 14, so as to open the valves 12 and 13. It will be noted, that the gas passing through the opening 11, and through-the inlets 10 are admitted in opposite directions, so that the currents impinge, thus assuring a perfect mixture. This is because the air Apasses from the port 10 past the lip of the valve at a slant to the opening 11, whereas the gas admitted around the lip of the valve 12 has a slant toward the opening or port 10. The result is that the gas and air have a movement in opposite directions as they" leave their ports, and will come together and be better mixed than they would be were they injected into the mixing chamber in the same direction or in a direction more nearly co-incident. The valve 12 preferably enters the opening 11 and the valve 12 and opening ll'being cylindrical, so as to permit of the telescopic movement of the valve relatively to the opening. The closing of the valve 12 does not interfere with the perfect sealing of the valve 2. It also allows of an initial opening of the air valve prior to the openin of the gas valve.
The gas passage is controlled by a butterfly valve 17, and the air assage by a similar buttery valve 18. T ese butterfly valves-are both carried by a stem'19 which extends through the walls of the case. An arm 20 is fixed on the stem 19, and a controlling rod 21 is connected with the arm 20.
Ordinarily the "arm 21would be connected with the governing mechanism, and by means of this the buttery valves are swung, so as to control the admisson 'of air and as. In this way the mixer controlling devices Vespecially the valves 12 and 13 may have a uniform motion, except as this may be disratentedMar. 14', 1911.
turbed by the variation in pressure incident to the opening and closing of the valves 17and18. i' Y The gas passage 7 is provided with a valve 22 preferably of the butterlly type mounted on the stem 23, and provided with the operating handle 24. By means of this valve the producer gas may be cut oil. A valve 25 controls the passage 26, connecting the air passage 8 with the passage 7. This valve 25 is mounted on the stem 27. The stein has the head 28 secured to it and this is screwed into a socket 29, and by means of this screw the valve may' be opened and closed. By means of this valve 26 air in regulated quantities may be admitted to the -the chest.
gas passage. The urpose of this is to dilute a richer gas, w en a richer gas is-used, so that the proper mixture will be maintained within the case 3. n
As a matter of convenience, and often as an element of safety, itis often desirable to have the engine connected with a separate supply of gas, usually gas somewhat richerthan the producer gas. For this purpose the valve chest is provided with the passage 30, into which the gas passage 31 extends. The gas passage 3l is controlled by butterfly valve 32. A gas valve 33 is arranged in an opening 34 in the Wall between the passages 7 a-nd 30, and connects these passages, the passage 30 being connected with the cylinder 33 throughports 35. The cylinder is connected with the passage 7 by the ports 36. A valve 37 operates within 'the cylinder 33, and is provided with ports 38 which may be brought intoand out of register with the ports 36 for regulating these ports. The valve 37 is carried by a stem 39, which extends through the walls of A gear segment 40 is fixed on the shaft 39, and meshes a segment 41 on the stem 19. In order to control the capacity of the ports 36, the cylinder 33 is provided with a stein 42, which extends through a .cap 45 closing the opening 4G in the chest through which the cylinder is inserted. A nut 43 is secured on the stem and operates on a stud 44. By screwing this nut on the stud 44 the c linder 33v may be raised and lowered relative y to the ports 38, so that the capacity of the ports through the openings 38 and 36 may be varied. By chan ing the capacity of the gas ports the qua ity of mixture may be varied. Producer gas is admitted through thel pipe 47. Air through the pas'- 'sane 48 and natural as or a richer as is admitted through the pipe 49.
'l`lie mechanism as shown is arranged for the admission of the producer gas. The valve 22 isopen, the valve 25 closed, and the valve 32 closed with the parts so arranged, producer gas passes from the pipe 47 through the passage 7, openings 9 passing the valve 12, and comes into contact with the air and enters with the mixture past the valve 2. Air enters through the pipe 48, passage 8, openings 10, past the valve 13 coming into contact with gas and passing with the mixture to the cylinder. The quantity of air and gas admitted is regulated by the valves 17 and 18, these being actuated by the arm 2O in the manner described, the valve 2 operating during the suction stroke, opens the valves l2 and 13 uniformly with each stroke, exce t as the pressure.varies by reason of the va ves 17 and 18 being closed. lVlien it is desired to operate the engine with natural gas, the valve 22 is closed, the valve 32 open; The natural gas passes from the pipe 49 past the valve 32, passage 30, openings 35 through the cylinder 33, and by way admission of a small amount of air through the passage 2G, so that a proper mixture may be maintained without varying the shape or operationof the mixer valves. The capacity of the openings 38 may be varied by raising and lowering the cylinder in the manner described, to adjust it for diil'erent qualities of gas, as well as the changing of the quality of gas through dilution. The engine is still controlled through the same operating lever by the action of the valve 37 in the manner heretofore described. All that is necessary therefore, to shift the mechanism from one kind of gas to the other is to operate the valves 25, and 32.
It will be noted, that the valve 12 telescopes the opening 11 slightly, and that the valve 13 just closes the openings l0, the result of this is that upon the initial opening of the inlet valve mechanism, the air is introduced prior to the introduction of any gas. This has been found to be desirable in practice.
