Since i ing an air-admissionV aperture or apertures to‘ ¿. the intake manifold and preferably moving a slide ' valve within an air-admission conduit of the type ' hereinabove speciñed. these parts are caused to rotate, there is a com bination of torsional and longitudinal forces Y Referring now to the drawing Ywhich illus which tend to _quickly dislodgeor, loosen any dust particles which may entrer the bearing 20 ,or which trates apreferred embodiment of my. in_vention,` ' l Ißrindicates the engine _as a whole which may bel ‘ of' any conventional type and as shown, is pro-Y vided with an intake manifold II having a headl .

Important as this is; jvecting screw-threaded nipple I4, atmthe _outer the propellerV ¿I8 has a further advantage in that regulating device I2, as moreîparti’cularly illus trated in Figs. 1 and 2.

The'valve memberv I'I' is movable by the'ro forceto the opposing surface. ~ ~ tatable propeller I8 which as shown is mounted,V on In the embodiment of my invention illustrated, a rod I‘B 'connected with the sliding valve-member suitable protecting Vmeans is provided to protect I'I.ï The rod IIB is guided at its o_uter end in the bore 20’ of cap 20 and'in the "preferred embodi-` 30 and prevent clogging of dirt in the air-intake ment`of my invention thev valve member I‘I fits loosely within the bore 2| of the tubular mem ber IB and' has' at one end a"«bevel1ed'edge 22 adapted to seat upon the valve seat 23 andto close a main- Valve opening 23’. The body lof 35 the- airfc'onduit'or casingflû'is'provided with a plurality of series ofapertures 24 and 24’. "Mylslide valve casing is -preferably positioned in inclined position on'thermanifold so thatfit will normally close by gravity. _*The threaded apertures“ and 24’, and'insaid preferred em bodiment of my invention, I provide a protective. casing 25 which, as shown, is mounted on spiders 26 and 26’ and is provided at opposite ends with the screens 2l and 2l',~s'aid casing 25 being, of course, open at its opposite ends -to permit air to pass through said screens 27'and 21', and into the intake openings 24 and 24’. ` - ` » - The operation of the Yinvention will vnow be 40 briefly described. When the automobile is run ning'at a low speed, which may be up to ten miles connections ~at I4, I5 permit some> angular move per hour, the valve portion 22 engages the seat ment so that'the angle of the casing can be ad justes. ’ ' y ' ` ' ' 23y to close the latter so that the combustible f mixturefor the motor is as determined by- the withinthe bore ofthe conduit casing I6 so as to 45 carburetor. This closing action is caused' by grav-ity and suction overcoming the pull of the pro admita l.slight Vamountpffair upon unseating peller I8. As the speed increases the valve I'I from the ,ivalve 'seat ‘23 Íthrough theírnain' valve mayV move to the position shown in Fig. 2, in opening >23’. 1 So soon, however, as the valve mem which' the valve seat 23 is open, and some air loer.'A I'I' is moved 'outwardly airis admitted through the inner members of the series of apertures v24 >50 leaks throughv the clearance between the side walls of the valve and of the tube I6. This- is and 24', and as said valve member I1 is` moved" desirable because the carburetor is generally ad further outwardly additional air will 'be Vadmitted justed for a rich mixture, that is, one in which through additional apertures of 'said'series until there is a considerable'` excess of fuel. As lthe the'entire 'plural series of apertures ‘24 vand :24' will be admitting air to the air-fintake conduit" 55 speed further increases and becomes substantial, or’casing'and through that conduit or casing toV the proportioning of fuel to air bythe carbu retor changes so that the mixture becomes rich-ï the manifold. In. preferred form of 'my invention illustrated,` erg-'because the coeflicients'of iiow vary „with the velocity of the gases in the carburetor, and for the plural series of apertures 24,> 2.4' are arranged in pairs and- these pairs'- arev progressively in 60 other reasons.

This Á l additional air is supplied to the combustible mix tion in relatively confined condition and will thus buretor, whereby the unburnt gases'r discharged enableY a constant?pull to be maintained :on the 70 ture ina Vturbulent condition" so as to instantly become a relatively homogeneous component of valve I'I. SuchV constant pull of the suction willv be jovercome by the propeller pull which is pro-v gressively increased and strengthened in accord;~ ance with and in proportion tothe speed of thej vehicle. the combustible mixture.. _v This 'is due-to the fact' that the air enters'the tube I6 >through 'opposed openings 24,' _24l so Vthat the streams of air A.irn pingeïon each other and cause eddying’which'in 2,406,282 5 , a round pipe, and in an elbow such as I5, quickly resolves itself into a pulsating and whirling ñow. The whirling or spinning of the air is aided in some degree by the rapidly rotating valve I‘I, which indicates a further advantage in the use of the propeller I8. Thus the air becomes quick- ` ly warmed up and is uniformly admixed to the combustible mixture. While all this transpires there is the constant interaction between the suc tion and the pull of the propeller, as adjustably 10 modified by gravity, so that it is seen that the motor and its fan cooperate with the valve struc ture and the rotating propeller to avoid waste of fuel and to maintain a highly sensitive interrela tion of the parts without requiring any direct ac tuator connection to the carburetor or the fan. It is noteworthy that the force of gravity is a constant quantity, and because the valve unit is inclined, that effect is small. But it is impor tant for moving the valve to close the ports pro 20 gressively and bring the valve into immediate and strong responsive relation to the suction when " 6 - the casing slidable `along the axis of the casing and rotatable about said axis, a propeller ro tatably slidably mounted on the casing and beingv axially connected to the valve so that the, lat ter is caused to rotate and the valve and pro peller are slidable as a unit, said casing having f openings communicating with the manifold and with the atmosphere for admitting a quantity of air to the engine sufficient to reduce the rich ness ofthe combustible mixture as the engine increases in speed, said valve bein-g gravitation ally urged to a position in which it closes the openings, and said propeller being opposed to the said fan to be rotated thereby and to produce an axial force causing opening movement of the valve, and said valve being so related to the cas ing that the engine suction tends „to close the valve, whereby rotation of the valve andV pro peller unit renders the same easily slidable in response to the opposing forces of said suction and of the fan blast. , v 3.
