lValves; and I do hereby' declare that the following is a full, clear, and exact description thereof.
My invention has for. its object to provide a simple and eective oil and air mixing valve for internal combustion engines, the construction and arrangement vbeing such that a percentage of air required is unobstructe y admitted to an upper mixing chamber independent of the remainder, which remainder together with oil is by suction drawn through a ort controlled by the usual check-valve. T us at all times the device insures a constant volume of gas, which-f'volume is sufficient for the charge required' to fill the engine-cylinder, and thereby prevents a partial vacuum therein due to premature closing of the aforesaid checkvalve.
The invention therefore consists in various peculiarities of construction and combination of parts as hereinafter set forth with reference to the accompanying drawings and subsequently claimed.
\ In the drawings: Figure- 1 represents a sectional elevation of a valve embodying the features of my invention, the section being indicated by line 1-1 of Fig. 2; Fig. 2, a plan sectional view ofthe same with parts roken, the section being indicated by line 2-2 of Fig. 1, and Fig. 3, a fragmentary detail illustrating the controllin handle and sector therefor of a by-pass va ve embodied in the device.
Referring by numerals to the drawings, 1
. indicates a casing, which comprises 'a lower air-chamber. This is separated from a casing 2, com risin a mixing chamber, by a division-wa 13, W ich wall constitutes a por-` tion of the casing 1. The casing v2 is secured to said casing 1 by bolts 4, and together these f casings constitute a single housing for the mixing valve mechanism, which in some instances may be cast in one piece.
The lower casing 1 is provided with a screw-threaded lnozzle 5 for the reception of an .air-supply pipe, not shown. The upper caslng 2 1s similarly provided with a nozzle 6 into which is tted a pipe (not shown) that is connected Ito the gas-chamber of the engine cylinder head, which chamber has the usual receiving valve therein.
The oil-supply is admitted to the housing through a nipple 7, which is threaded toreceive a supply-pipe, there being a duct 8 at a right-angle to the nipple, opening into the bevel face of a valve port 9. Tlns duct is controlled by a pin-valve 10 whereby the oil-supply may be regulated to suit the ex-l isting conditions. A. bevel-face check-valve 11 isfitted into the port 9 having a stem 12, which stem is guided in a sleeve 13 projecting from the lower wall of the casing 1. The stem is shouldered and counterbored at its lower end `for the reception of a coil-spring 14 which surrounds the valve-stem and is interposed between the' shoulder of the sleeve and a collar 15 fast on the end of the 'valve-stem.
the butter-fly valve is opened sufficiently to insure a constant full-charge. byass 16 being restricted, when a suction- A ter the engine is started Owing to the stro e of the piston takes place, the first air drawn into theupper mlxing chamber will pass through said by-pass, but owing to the atters limited area, the vacuum will cause a,
lift of the check-valve to supply a sufficient quantlty 'of air.v The lift of said check- Valve also opens the oil-duct 8 and is oil drawn into the mixing chamber together with the air causing amixture therein which is delivered into the combustion chamber of the cylinder, and as the -piston continues on its forward stroke a constant air-supply is added through the by-pass 16, though the suction is insulicient to hold the by-pass is not employed. Thus a perfeet mixture of the charge is insured by adding air thereto through the byfpass 16,
,which airserves to prevent an overrich charge of gas, a condition that would attain if the check-valve should be held open during the entire stroke of the engine, 1n which case oil also would then be continually added to the air.
y chamber `V'vent a spatter of oil 'in the mixing-chamber l and a consequent over-rich charge on the next operation. The desired result is obtained by reason of the lower chamber, which when the check-valve -closes will receive any spatter of oil, the upper or mixing being at all times clear of such accuinulations.
the check- .valve open, a condition whlcli exists wherein Another' advantage of the I claim:
1. A Innung-valve comprising a housing having a division-wall, a port in the division-wall, an oil-duct in connection with the port, a check-valve closure for said port and oil-duct, a b -pass aperture inthe division-Wall, low the division-'wall and an air outlet in said housing above said division-wall.
2. AA' inixing-valve comprising a housin having ya division-Wall, a port in the division-Wall, an oil-duct in connectionwith the port, a check-valve closure for said port andA oil-duct, a by-pass aperture in the division-wall,y means for regulating the area of the by-p'ass aperturel an air inlet in the housing below the division-Wall and an airoutlet in said lhousing above said v"divisionwal v 3. A mixing-valve eornprising'a housing an air-inlet 1n the housing behaving a division-wall therein, whereby an upper mixing chamber and a 'lower airchambery are formed, valve controlled air and oil-inlets in the division-Wall, and an fi air by-pass aperture in said division-wall of less area than the valve-coiitrolled air-inlet.
In testimony that I claim the foregoing I have hereunto set my hand at New Holstein, in the county of Calumet and State of Wisconsin in the .presence of two witnesses.
