' pipe.
or out to reduce it.
In order to prevent dust or otherv particles from passing to the engine through theair-valve I place a screen 23 in the 'pou'- pling 10, seating it upon the shoulder 27, the latter being formed, as will be noted, by reason of the threaded bore' 28 which receives the inner end of the valve-casing being larger than the bore 29 leading to the intake For convenience in fitting the plug and piston in the valve-casing the flanged cap 17 may be made separately and subsequently secured to the plug, as shown in Fig. `3, orv
the.l disk -19 made separately and similarly attached, as shown in Fig. 7 the latter con-- struction being required lwhen theA additional feature is used forming the modification which I shall now describe. In this modification I employ an auxiliary valve device in the form of a washer 30 mounted to work on the stem 18 and almost completel close the inner ends of the ports 20 throng the valve-plug 16,'said washer or disk-valveA being moved to normally` closed position against the inner end of t e plug by means of a light helical spring 31 interposed between the same and the piston 19.` The spring is light in order to permit the said valve to unseat when there is a light current of air through the ports 20, and llose when the engine is at rest, or when there 1s very little suction; the utility of this device being hereinafter' more fully explained.
The a'ir supply' valve hereinbefore described may be applied to the manifold intake pipe 25 at any point between the carbureter 32 and branches 25, 25a of said intake pipe leading tothe engine-cylinders, by simply tapping said pipe to receive the coupling 10; but I prefer to make the connection b lmeans of a plate 33 adapted to be readil'y inserted between lthe lower iianged. end 25b of the intake-pipe 25 and the corresponding connection flange 34 on the carbureter, for which purpose said plate .is provided vwith apertures 33a to receive the attaching-bolts 35, and with a tubular projection 36 threaded internally to receive the coupling 10. The attaching-plate is rovided with a central opening correspon with the bore of the intake pipe 25, and into this opening leads a passage 37 communicating with the coupling.
' It will be understood, of course, that any type of carbureter may be used, that herein shown being merely a conventional type employed for illustrating thevapplication of my invention which lrelates to the air valve mechanism.
In the operation of my improved valve it remains open (Fig. 3) until the suction caused bly runnin the engine createsfa rush of air t rough t e ports 20, and this air.
striking against the piston i9 on its way to the ports 21 will close the valve (Fig. 4) when itis of suiiicient' force to overcome the strength of the, spring 22, thevalve power of the engine, simply reducing the y richness of the mixture at the proper time. Conversely, when the engine slows down the suction increases suiciently to close the valve and the usual mixture, for which the carbureter has been adjusted, is fed to the engine. A
The form shown in Fig. 7 is particularly adapted for automobiles, particularly those in which the engine is started manually by 4means of a crank or like contrivance. In this instance the disk-valve 30 maintains the valve practically closed, instead of fully open as shown in Fig. 3, so that in starting the engine a rich mixture will be supplied through the manifold intake pipe, and when the engine begins running at low speed the suction will cause the plug 16a to close, after which, at high speed, the sprin 22 will open the'valve and the supply o air coming in through the valve will have to merely overcome the power of the light spring 31. p
Having described my invention, I claim:
1. An air valvefor the manifold intake of gasolene engines-comprising@ coupling, a tubular casing threaded therein, a plug working in the outer ortion of the casing and provided with a ranged cap closing against the end of said casing, said plug having openings leading through the same from the sides to the inner end, means for limiting the outward movement of the plug, and a spring acting to` normally open the valve.
