AUXILIARY AIR-VALVE FOR CARBURETERS.
Application filed July 2, 1917.
new and useful Improvements in Auxiliary,
Air-Valves for Carbureters, of which the following is a specification.
This invention relates to improvements in auxiliary valves for carburetors. It has as its principal object the construction of a device of this character to regulate the amount of fuel being used. In this manner the proper mixture of fuel and air is obtained thereby securing maximum engine efficiency.
Another object of the present invention is to so construct the device that the same may be manufactured from sheet metal thereby securing a device which is light in weight and materially lessening the cost of manufacture.
With these and other objects in view, the invention consists of certain novel features of design and construction herein illustrated and more specifically pointed out in the appended claims.
Referring to the drawing forming a part of this specification,
Figure 1- is a view in side elevation of my improved device showing the same attached to the air intake of a carbureter.
Fig. 2 is a view in end elevation of the same.
Fig. 3 is a longitudinal cross section.
Referring to the corresponding parts of the several views by the same numerals of reference, 1 denotes a carbureter having the air intake 2. To the latter is attached my improved valve which comprises the sleeve portion 3 provided with a suitable boss 4: through which passes the screw 5, the point of which engages the intake 2 thus securing the device to the carbureter. On the opposite end of the sleeve is formed an annular on its outer edges the conical portion 10.
The diameter of the latter is somewhat less Specification of Letters Patent.
Serial No. 178.311.
than the inside diameter of the flange 5 thereby giving an annular opening 11 between the two parts.
The spring 13 is interposed between the V inner surface of disk 9 and the head 8, while a second spring 14: is interposed between the outer surface of the disk and the inside of yoke 6.
In use the device is attached to the carbureter as shown and the tension of springs 13 and 1 1 is such that the disk 9 is normally positioned as shown in Fig. 3 or, in other words, with the edge of this disk opposite the edges of the flange 5.
Under these conditions, when the engine is running at slow speed or light load, the opening 11 gives suflicient air to produce the proper combustible mixture. However, as the speed increases and the vacuum produced by the pistons becomes greater, more fuel is drawn through the supply nozzle of the carbureter and more air is required. In this case the suction draws the disk 9 against the tension of spring 13 thereby increasing the opening between the edge of flange 5 and the face of the angular portion 10, and the farther this disk is drawn into the sleeve the greater will be this opening.
In cases of pre-ignition with the intake valves open, the pressure thus produced within the manifold and carbureter will find an exit by forcing the valve 9 outwardly against the spring 14 thus preventing any danger or rupture of the associated parts.
It will be noted that the construction adapted for this device is such that all parts may be formed of sheet metal thereby producing a device which is light in weight, accurate in size and which is cheap to manu- Patented July 2.7, 1920.
facture, and it will be understood that while I have shown the preferred embodiment of my invention, changes within the scope of the claims may be made in detail of construction and design without departing from the spirit thereof.
I claim as new and wish to cover by Letters Patent 1. An air intake valve comprising a sleeve, an annular inwardly extending flange formed integrally on the outer end of said sleeve, a yoke extending outwardly from said sleeve, a pin secured to said yoke and extending axially into said sleeve, an abutment formed on the inner end of said pin, an elongated sleeve slidably mounted on said pin, a disk having a conical outer surface on said sleeve, said disk being concentrically disposed within said flange so as to allow an annular opening therebetween, and springs extending between opposite sides of said disk and said abutment and said yoke to normally hold the edge of said disk in position in the plane of said flange.
2. An air intake valve for carbureters comprising a cylindrical sleeve secured thereto, an inwardly extending radial flange on the outer end of said sleeve, a pin extending axially into said cylinder and secured thereto, a disk having a conical outer surface slidablymounted on said pin and spring means on opposite sides of said disk for normally holding the outer edge thereof in the plane of said flange.
In testimony whereof I aflix my signature. 20
