on. i? of the cerbureter pro- .til the usual manifold (not shown}. semi outlet is controlled by a Well lmown .4 surrouncis spray nozzle and provicles in passage. The lower enc'l EZl of said sleeve is of coniesl form. to increase the air on, the interior of said sleet e st that point. The said sleeve controls the supply of air to the spray nozzle and is vet-ti celly movable, subject to elevation by the suction clue to the air passing the spray nozzle. The operation is such that the volume of air is proportional to the demands of the engine. The movement of said sleeve 20 is controlled by gravity, or preferably by a spring 22 which encircles the upper part thereof. The said spring an sleeve are inclosecl by an outer sleeve or cylinder to be again referred to. Its normal position is shown in 1 and 5. In order to re dues the supplyoi air and to thus procluce it mixture of greet-er rie llhiiSS -when such leeeoiries desirable, for example, insure a ready starting of the engine'the sleeve 29 may be lowered to reriuoe the volume oil? air supply. See Fig. 3. The ssicl sleeve :20 is vertically movable, independently of or with the outer cylinder 23 wfoielz supports it. Thesaiel outer cylinder 23 is provided with. a lower contracted 52% upon which the sleeve 20 rests and with on upper flange 25 "which forms a guide for the up yer end of said sleeveQO. The said cylinder 28 is vertically movable in the annular Wall 11 and is hel. in an upper position by s springQZ. The upper position ofssitl cylinder 23 con trols the normal position of sleeve 2G is ecliusteri by a screw 28 "which engages per flange 25 of said cylinder. the screvv 28 is mounted in a boss 29 extending from the upper portion 17 of the seeing and is proviriei. with s locking spring See Fi 5. 1
