CARBURETER.
raaass carburetors, and it consists in the constructions, combinations and arrangements here in described and claimed.
An object of my invention is to provide an atomizer which can be readily adapted to a carbureting device to improve the action and make it more eihcient.
bine said improved atomizer with the desirable features of my improved carbureter, Patent No. 1,180,889, whereby a more improved vaporizing or carbureting device is obtained.
The following specification and the appended claims make clear my invention in detail.
My invention is illustrated in the accompanyin'g drawings which form a part of this specification in which- Figure 1 is a vertical section through the device,
- 2 a vertical section through the atom izing portion. of the air passage of the device on an enlarged scale, and
' Fig. 3 is an angular section cutthrough the passage-way at the center line of the jet 4 to show the cross-section of the passageway with the trough 7 in position without the jet 4 or the adjusting needle 12.
In carrying out my invention 1 provide the main air passage 1, having a draft controlling valve 2 arranged in the inlet, thereof, and the manually operated throttle arranged in the outlet, thereof. lhe fuel inlet or jet 4- protrudes a portion of the way into the air passage 1, being fitted into the boss 5, andis fed by a constant head of fuel carried in the bowl 6 by means of the float mechanism shown and well known in ,the
art. Communicating with the fuel jet 4: and
extending across the air passage 1 is arranged the trough Z', the lovven portion, thereof, surrounding the jet 4 1n the cavity 8, and the u per end of which is fitted into the wall of t e air passage 1 for support, and the open side of which faces toward the outlet of the air passa e 1. It will be seen that the cavity 8 extendia just beyond the top of Specification of Letters Patent. Patgntefl NOV 13, 1917. Application filed June 27, 1916. Serial No. 106,248.
the jet 4 and that the lower portion of the trough '7 is cut back to about the center for the purpose of allowing a free discharge from the jet 4. In the back side of the trough 7, in communication with the cavity 8, IS the air inlet 9, which is in communiontion with the atmospheric side of the valve 2 by means of the secondary air passage 10 in the form of a tube, which is attached to thetrough 7 by some means such as brazing. The outlet of the jet 4: is most desirably formed into a crater portion 11 into which the adjusting needle 12, having a cone shaped head, is arranged. It will be noticed A that the needle 12 is crowded to the back Another ob ect of my invention is to coinside of the outlet 11, which allows of a crescent shaped spray from the jet t on the open side of the trough 7. v
The above description should. suilice for showing how my improved atomizing device can be applied to any carbureter or vaporizer, as well as my improved carbureter, Patent No. 1180389, to which the drawings conform. It will not be necessary to describe the details of these drawings as this has already been done in my-former specification. 7
It will be seen that in the operation of my improved device that the velocity of the air by the trough 7 creates a partial vacuum, therein, which is communicated to the jet 4 and the air inlet 9. This induc- .tion is in addition to that static head generally realized by the depression of pressure in the air passage 1, and is more in efi'eot at high speeds than at low speeds, increasing the range of the jet 4. The static head induced by the trough 8 combined with that of the air passage 1 is communicated to the jet & and the air inlet 9 in the trough 8, but the air being lighter and less restricted than the fuel, very little static head is realized at the jet 4, as it is practically all transformed into kinetic head. Thus a more efficient atoinizing s efiected, especiallylat low speeds,
