The invention includes a casing composed of an upper section 1 having an attaching flange at its u per end, and a flange 3 at its lover end, tlie latter being sured by means of rivets or vbolts 4 orv the like to a. similar flange 5 carried by the lower section 6 of the casing.' The lower section 6 has its bottom formed with a central opening 7 and an annular chamber 8, there being a gasolene supply pipe 9 formed integral with the lower section 6 having its inner-'end disjectsl will nlater alp# charging into the chamber 8. The nozzle 10.

snugly fits Within the opening 7 of the bottom of the lower section and has its head 11 projecting outwardly therefrom to forin an annular shoulder 12 which seats ou the upper face of the bottom of section 6 and there by restricts the downward movement of the nozzle.4 Head 11 is formed with channels 13 which are of angular contour and which ,air

In Figs. 45 and 6 are shown two different forms of disks, Fig. 5 showing a plain disk of ring-likeforin and Fig. (i showing a. dill ferent form ofslotted disk. The disk designated 14 is shown in Fig. 1 as seating on the u pper edge of the nozzle head 11, it. beingobvious that by theuse of the plain disk a com 1ete=flow .of gasolene-is had.

The, throttle valve 30 is ui-voted in the upperend portion of the upper section 1 of the casing, and is rigidly connected to an Yarm :il which latter is formed with an eye 32 for connection with any suilable operat right angles to the course of travel of the air, the latter entering the 'nozzle through thevair inlets 19 and courses upwardly. Thus p the gasolene is supplied to the air on the outer circumference of the latter or at right :ingles to its course of travel. It will further be seen that the cone-shaped valve is so connected to the throttle that as theV 1.
