Application May 18, 1934, Serial No. 726,422 4.1 Claims. ((31. 137-—139) This invention relates to improvements in an There are brackets 26 mounted on the inside automatically controlled valve, and more partic of housing 23, which support the ends of both ularly to a simple device that automatically con trols outside air or vapor supplied to the intake tubes l? and i9, leaving a vertical opening 2?, between the tubes. There is a vane 28 having a 0 manifold of an internal combustion engine. right angular section 29 with a port 38, this vane An object of this invention is to furnish an Cl 28 is hinged at its center or fulcrum 3i and nor easily adjustable means for automatically regu mally hangs in a verti lating the amount of free air or vapor supplied cal position but springs or counterweights or both may be used as a modi?ed to the combustible gas through the intake mani of returning th e vane to its normal posi 10 fold of an internal combustion motor, without means tion. any additional carburetor adjustment. Another object of this invention is to furnish an automatically controlled valve for supply air or vapor, the amount of vapor being increased 15 as the speed of the engine increases and reduced as the speed of the engine is reduced, taking care of the change in air supply necessary with the variation in engine speed. With the above and other objects which will 20 be apparent as the description proceeds, my in vention consists of the following novel features and method of construction which are illustrated in the accompanying drawings and pointed out in the appended claims. 25 In the accompanying drawings, Fig. 1 shows the device in its entirety attached a conventional type of internal combustion engine, supplying the vapor from the crank case, to illustrate the principle of the device. 30 Fig. 2 is a perspective rear View of the auto matic control valve. Fig. 3 is a front view of the automatic control valve. Fig. 4 is a cross sectional View of the control 35 valve showing the valve arrangement. Fig. 5 is a fragmentary cross sectional rear view of the automatic control valve showing its detailed construction. Referring to the drawings in detail where like 40 characters of reference denote corresponding parts, character iii indicates an internal com bustion engine having a fan ll actuated by belt l2 working off of the crank shaft it, there is an automatic control valve ill supported by a con 45 ventional bracket 55, which is fastened thereto by screws at 24, and to the engine it by means of bolt [6, the tube ll, leading from the breather spout IS in the crank case of the engine and a tube l9, leading from the control valve it, to the 50 vapor inlet 28, which is placed between the car buretor outlet 2i, and the intake manifold 22, the control valve 14 consists of a housing 23, hav ing holes 24 at its top for attaching bracket l5. The front of the housing 23, has louvres 25 to 55 permit the air to enter. There are radial slots 32 on the side of housing 23 to act as an indicator for vane 28. In operation the automatic control valve 14 is mounted on the forward end of the engine imme diately behind the fan l l, or any other convenient location. In the drawings it is fastened at 24 to an angular bracket 0 r support l5 bolted down 15 onto the engine with bolt it, there is a tube l7 leading from either the breather spout [8 in the crank case of the e ngine, the radiator, or any auxiliary air or vapor supply, this tube is led into the control valve M terminating at a point near 0 the center of the valve I4 leading to the air or vapor inlet 20 clamped between the ?anges of the carburetor 2! and the intake manifold 22, the control valve M has a vane 28 pivotally mounted having a ?at section 29 at right angle to the vane 5 28 operating between the ends of tubes I‘! and H9 at 2?, the ?at section 29 of the vane 28 has an aperture or port 39, and when the air from the fan i l is blown through the louvres 25 into the housing 23 of the control valve M, the vane 30 28 is forced backward swinging on its pivot 3| causing the port 36 in the ?at section 29 to reg ister with the ends of the tubes ll’ and I9. The operation of the pistons in the cylinders of engine it causes a suction, drawing in the 35 gaseous fumes through the intake manifold 22, from the carburetor 2! and in doing so also creates a suction in the tube 19, when the port or aperture 36 registers partially or fully with the end of the tubes IT and 89 this suction is further proportionately imparted to the tube ll drawing the air or vap or to mix with the gases in the intake manifold 22. The entire installation of this device can be made without any mechanical change or altera tion in the construction of the internal combus tion engine, whether used on automobile, aero plane, or motorboat, a nd will automatically con trol the amount of air or vapor drawn into the combustion chamber through the intake mani fold 22, depending on the velocity of the air con tacting the vane in the control valve. It is obvious that the fast er the engine is run the greater the velocity 0 f air hitting the vane 28, 0 2 2,085,348 whether this air is produced by the fan ll op erated by the crank shaft E3, or whether it is produced by the speed of the automobile, aero plane, or motorboat. The more air hitting vane 28 in the control valve 54 the wider it open the port 31! and the more air or vapor be drawn into the combustion chamber of the will will the motor.
