13 Claims. (01. 251-11) The main objects of this invention are: ventionally illustrated, the carburetion being of First, to provide a throttle valve for internal the so-called down-draft type. combustion engines which is not only effective as My improved throttle valve comprises a tubua throttle valve but is highly effective in mixing lar casing 6 which is designed to be interposed the air and carbureting fuel passing the valve, between the carburetor and the manifold. The and even distribution of the gas. device is preferably cylindrical, as illustrated, and Second, to provide a throttle valve comprising provided with an annular shoulder I and with a plurality of leaves operatively connected for Wall bores 8 constituting bearings and located simultaneous actuation so that when partially above the shoulder. These bearings 8 are disopened, they present a propeller disposition of posed in the same transverse or horizontal plane leaves whereby a swirling motion is imparted to and are spaced 90 apart. A support 9 is disthe fluid, the pitch of the blades being varied in posed centrally or in line with the longitudinal proportion to the opening and closing of the axis of the casing and is provided with bearings valve, and the parts being arranged so that when l8 aligned with the wall bearings 8. To facilitate fully open, a minimum of obstruction is presented. assembly, the support is provided with a bearing Third, to provide a throttle valve having the cap llheldin place by the screw l2. Cross pieces above desirable features and characteristics which I3 are provided, these supporting the member 9 is simple and durable in its parts and highly from the wall of the casing. A gear ring I4 is efficient in operation. mounted on the shoulder for rotative movement Objects relating to details and economies of about the casing. Pinion gears 15 are journaled my invention will appear from the description to in the wall bearings 8 in meshing relation with follow. The invention is defined and pointed out the annular gear 14. in the claims. The complementary segmental valve plates or A structure which is a preferred embodiment leaves It are provided with spindles l1 journaled of my invention is illustrated in the accompanyin the bearings of the central support and coning drawings, in which: nected to the pinion gears for rotation therewith.

Referring to embodim t t t d Throttle valves of the commonly used type, 1 f 1 us F m the so-called' butterfly type, serve, when the enrigs. l to fi inclusive of the drawings, I indicates gine is Operated at low Speeds and especiauy in pa of an Internal combustlfm engme, 2 a manistarting, to collect or baffle the gasoline so that fold. 3 a Carburetor having an ake indicated it does noteifectively mix with the air anddrips at and 5 an filter- These P t ar al from. the valve. This butterfly type of valve also lib results in an uneven distribution to the cylinders. This disadvantage is eifectively overcome in my improved valve because the arrangement of the leaves is such that a very tho-rough agitation results and a wiping swirling action of air is set up across the valve blades or leaves, this being violent at low speeds and varying with the speed commonly resulting with the degree of opening of the throttle.
Referring to Figs. 7 and 8 of the drawings, there is illustrated a modification of my throttle valve wherein the control ring ii is provided with radial pins 22 spaced 90 apart. The spindles23 of the valve leaves are journaled to the wall bores 25 and have levers 25 at their outer ends provided with slots receiving the pins 22 sothat when the control ring is rotated the valve leaves are turned in unison and to the same angular extent.
In the modification, the leaves are provided with offset flanges 23 which are adapted to overlap the edges of the adjacent leaves when they are in closed position. The control ring 2! is adapted to be rotated by the throttle wire 2a which is connected to oneof the pins 22 by of the coupling member Bil. Otherwise, the valve of the modification is substantially similar in construction and operation to the preferred embodiment of my invention.
In the modification illustrated by Fig. '9, the case 31 is provided with diametrically opposed bores in which are journaled the outer end of shaft 32 and the sleeve 33, the shaft extending through the sleeve for rotary movement therein. The shaft and sleeve are provided with semi-circular vanes or leaves as and 35 which are adapted to be turned in opposite directions as indicated, the leavesibeing provided with offset flanges 35, 35 for overlapping the corresponding edge of the other leaf when they are in closed position. The leaves are operated by means of levers 3'! and 38 which are connected respectively 'to the shaft and sleeve, the free ends of the levers being connected to the control member 39 by the knuckle 4B and links :42 and 63. The arrangement is such that when the control member '39 is reciprocated the valve leaves 34 and 35 are turned in opposite directions to open and close the valve and when partially open impart a spiral or swirling motion to the fluid traversing the case 3 l.
I have illustrated and described my improvements in embodiments which I have found very practical. I have not attempted to illustrate or describe other embodiments or adaptations, as it is believed this disclosure will enable .those skilled in the art to embody or adapt my improvements as may be desired.
