HARRY R. JACKSON, OF CHICAGO, ILLINOIS, ASSIGNOB. OF ONE-HALF TO HENRY A. MAY, OF CHICAGO, ILLINOIS.
GOVERNING VALVE FOR INTERNAL-COMBUSTION MOTORS.
Application filed July 5,
- To all who/mir may concern:
Be it known that I, HARRY R. JACKSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Governing Valves for Internal-Combustion Motors, ot which the following is a specification.
My invention relates to distributing valves for internal combustion engines, and the object ot theinvention is to provide means interposed between the throttle vvalve and the engine cylinder for deecting the fuel vapor away from the sides of the intake duct and to' homogenize the vapor entering the intake manifold. I obtain my object by the mechanism illustrated in the accompanying drawing in which Figure 1 is an assembly view showing my device associated with a carburetor, throttle valve and intake manifold.
Figure 2 is a sectional view of the device taken longitudinally through the axis of the intake duct.
Figure 3 is similar to Figure 2 but shows y the valve elements in closed position. Figure et is a sectional View on the line L1-11, Figure 2. l
lFigure 5 is a-ace view of the device showing the upstream side and looking down stredm, and
Figure 6 is a face view of one of the valve elements.
Like numerals denote like parts throughoiit the several views. f' f I/Vhile the parts with which my device are associated may assume a wide varietyv of forms, I have illustrated them conventionally in Figure 1 in which 1 represents the intake manifold of an internal combustion engine, 2 represents the-carburetor, 3 the\in take duct, and 4 a common type of throttle valve. My 'device is designed to be placed in the intake duct 3 between the throt- .tle valve and the engine cylinder and has a casing 6 which is held in place by any suitable means, for example, bolts 8 which pass through it and through flanges 9 formed in the proximate ends of the duct 3.
The casing has a central passage 12 in line with the duct and within this, on o posite sides, are mounted two rotatable va ves 14. These are, in the main, cylindrical, but are cut away in such manner as to form curved' acting faces 15 which conform to the Walls ofthe duct when the valves are in open position as shown in Figure 2. It is desirable that passage l2 be somewhat constricted at the point 16 near its upstream end, thus producing a venturi eii'ect. The valves 14 may 60 be rotatably mounted in various ways. In the present case they are bored longitudinally at their axes to receive pins 18. One end,.19, of these pins, bears in one side ot the casing as shown in dotted lines in Figure 5. At the opposite end the valves have sleeves 20 which project out through the casing and are attached to a spring 22 which will be hereinateragain referred to. In the present case the pins 18 are secured by dowels 24. 70 as shown in Figure 5, thus being nonrotary, although the specilic construction may be varied. The valves are seated in cylindrical chambers 25 and according to the design shown, at a point midway between their ends about one-half of the valve is cut away.A A tapered recess 26 is formed lin the face of each valve at the middle,
the purpose being to cause the gases to converge tow ard the center of the duct when the .valves are partially closed. Another purpose is to form a bleed passage so that the valves will never be entirely closedin the sense of being air tight. It is desirable for the same purpose to form bleed passages 28 85 inV the valves, as best shownin Figures 2 and 3.
more nearly the throttle valve is closed, the" weaker will be the flow, and hence the more nearly closed will be the valves 14. As the suction increases, due to the opening of the throttle, the less need there will be for my valves. not only because the throttle itself has a lesser tendency to deflect the gases laterally, but because at higher speeds the engine cylinder becomes hotter by convection, and the heat of the intake manifold and duct is correspondingly increased. The elevated temperature of the .intake duct and manifold tends to prevent a. deposition of the fuel in liquid form, and hence the device is automatic. The greater the need of the deflectingvalves, the greater will be their de- Hecting effect, and vice versa.
lt will` be noted that the valves in my device face upstream` that is to say, in rotating from open to closed position the acting faces rotate toward the oncoming stream and yield when the energy of the stream increases. They consequently have little throttling effect, the throttling effect being cont-rolled by the throttle 4 which is oper- 'that these ed manually and is independent of the distributing valves. lt will also be noted 'alves are hung in the middle in the sense that the axes are 1nid\ 7ay between the edges of the acting faces. This makes them less sensitive than if the axes were at the upstream edges, and hence they require a spring of less strength to hold them to their work.
Having thus described my invention what l claim as new and desire to secure by Letters Patent is:
l. In a device for governing the flow of gas in the intake of an internal combustion engine, a valve casing having a central passage adapted to form part of the intake duct, cylindrical valves rotatably mounted on opposite sides of said passage and being cut away to conform when open to the walls of theipassage, means for yieldingly urging the valves to rotate in a direction to turn the acting faces upstream and thereby deflect the gases towards the center of the duct, the valves having tapered recesses in their acting` faces converging down stream for enhancing converging effect on the gases.
2. ln a device for governing the flow of gas in the intake of an internal combustion engine, a valve casing having a central passage adapted to form part of the intake duct,
