To all whom it may concern Be it known that I, MARCELLUB R. BnN- Nm'r, a citizen of the United States, residing at WilkesBarre, in the county of Luzcrne and. State of Pennsylvania, have invented new and useful Improvements in Air-Valves for Internal-Combustion Engines, of which the following is a specification.

This invention relates to improvements in air valves for internal combustion engines and has particular application to a valve whereby air may be admitted to the gas intake pipe of the engine in any desired quan tity or volume. A

11 carrying out the present invention. it is my urpose to provide an air valve which will manually controlled and whereby any desired volume ofair may be drawn into the gas intake pipe of the engine between the manifold and the carbureter and whereby any'preseure due to back firing will be auto-- may relieved.

Tit/fa also my purpose to provide a valve of t/he class described which will be constructed in such manner that the air will be drawn into: the gas inlet pipe in the form of streams thereby breaking up the gas passing through the supply pipe and into the manifold and ,Furthermore, I aim to provide a valve of the type set forth whereby the air drawn into the gas inlet pipe will be in the form of streams and maintain its force, incident to the stream formation, for a relatively long time. thereby efi'ectively commi'ngling with the gas passing through the pipe and breaking up the same with the result that an cilicient combustible mixture is produced with a minimum consumption of liquid fuel.

With the above and other objects in view,

combination and art angemeut of parts here inafter set forth in and falling within the scope of the claims.

In the accompanying drawings: Figure 1 is a view in side elevation of an internal combustion engine equipped with an air controlling valve constructed in accordance with the present in iention. Fig. 2 is a transverse sectional view through the gas intake pipe showing the valve structure on an enlarged scale. Fig. 3 is a view in side elevation of the valve removed from the pipe. Fig. i is an enlarged vertical sectionalview therethrough. Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 4.

Referring now to the drawingsin detail,

1 designates the 'carbureter or vaporizer of an internal combustionv engine, while 2 indi' cates the manifold connected with the cylinders and 3 the gas supply pipe connecting the carbiu'eter with the manifold.

Located in the supply pipe 3 and designed to admit air thereto is my lmproved air F2- ulating valve, such valve comprising, in present instance, a cylindrical sleeve 4 threaded into an opening in the supply pipe 3 at. a suitable distance above the carburetor. Arranged within the sleeve l longitudinally thereof is a seriesof tubes 5 opening into the supply pipe 3 and having the outer ends thereof flush with the outer edge of the sleeve t. Threaded onto the outer end of the sleeve 4 is a collar 6 preferably of noncircular contour, while secured tothe collar is a plate 7 having an openin formed therein registering with the s eeve 4. Projecting outwardly from the plate 7 above the connection between the plate and sleeve is a. pivot pin 8 and pivotally moiuitcd upon such pin is a closure in the form of a. plate 9 lying in face to far-e contact with the plate.7 and designed to close the outer ends of the tubes wi hin the sleeve 4. Projecting outwardly from the outer face of the'closure plate 9 and registering with he sleeve 4: is a cylindrical valve casing 10 coaxial with the sleeve 4 and arranged within the valve casing 10 is a valve disk 11 constructed of fiber or other suitable material and provided wi h a stem 12 extending into the casing it). Surrounding the stem 12 is a coiled expansion spring l3 having one end abuttingthe disk and the opposite extremity in engagement. with the end wall of the valve casing 10. such spring holding the valve disk in frictional engagement with th outer end of the sleeve 4-, such end of the s eeve constituting a sea; for the disk when the closure plate is in closed position. The outer end of the pivot pin 8 is equipped with a head 14. spaced apart from the outer face of the closure plate 9 and encircling the projecting end of the pin is a coiled expansion spring .15 abutting the confrontingportions of the head" 14 and the plate 10 acting to hold theconfronting faces of the closure plate Land the plate 7 in frictional engagement" and permitting movement of the closure plate about the pivot pin to uncover the outer ends of the tubes 5 within ithe sleeve 4 so edge of the closure plate so as to hold such plate normally in closed position andreturn the same to such position upon the release of the arm 16.

From the foregoing description taken in connection with the accompanying drawings, the construction, mode of operation and manner of employing my invention will be readily apparent.

Assuming the air regulating valve to be installed as illustrated in Figs. 1 and 2, the operator of the vehicle manipulates the respective lever and so causes the arm 16 to swing the closure plate 9 about the pivot pin 8 and against the action of the restoring spring thereby uncovering the outer ends of the tube As the outer ends of the tubes are uncovered, the air rushes into the gas supply pipe 3, incident to the suction created in such pipe in the operation of the engine. It will be noted that the air passing through the tubes 5 is projected into the gas supply pipe in the form of jets or streams thereby increasing the force of the air and effectively breaking up the gas passi to the manifold and commingling therewlth so that a highly combustible mixture is produced with a m nimum consumption of gasolene. It will be. seen that any number of tubes 5 may be brought into service independently of, the remainin tubes thereby permitting the volume of air passing through the regulating valve to be regulated in accordance with the speed of the engine.

When the closure plate is in closed position, the valve disk 11 seats upon the outer end of the sleeve 4 and is held against such seat by means of the spring 13 thereby effectively closing the outer ends of the tubes 5.

Should the engine back fire, the pressure thus setup will cause the valve disk 11 to disengage the seat against the action of the spring 13 thereby relieving such pressure.

lVhile I have herein shown and described one preferred. form of my invention by way of illustration, I wish ,it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without departing from the spirit of the invention. For instance, a. metallic plug having a series of longitudinal passages therein may-be substituted for the plurality of tubes within the sleeve, or any other structure may be utilized, in place of the tubes within the sleeve, which is capable of delivering air to the intake pipe or manifold in individual jets or streams.
