ture remaining perfect for all speeds of rota- The fuel economizers used heretofore consisted in devices affording a more or less automatic complementary admission of air or means for recovering the oil gases or for preheating the fuel.
The device according to my invention provides on the contrary an automatic variation of the amount of gasoline used according to the load on the motor together with a better atomizing whereby the eilicienoy of the fuel is increased.
According to my invention the nozzle the bottom which is provided with the usual calibrated fuel admission port comprises a stationary tube inside which a movable tube is adapted to slide, said movable tube passing more or less out of the stationary tube into the suction chamber according to the speed of the motor, under the action of the flow of gasoline or of the suction of the motor.
The movable tube is moreover provided preferably with ports or apertures which are gradually uncovered when the movable tube passes out of the stationary tube. These ports have preferably a helical shape. n
In another form of execution the fuel passes out of the upper end of the nozzle through .a plurality of ports instead of through a single hole.
The nozzle according to my invention may be adapted according to the case to any carburetor withV which it may be desired to use itwithout anyV modication to the said carburetor.
f I have shown by way of example on appended `drawing twoforms of execution of my invention.
Fig. 1 is a longitudinal cross-section of a carburetor nozzle according to my invention, in the position occupied by it when the motor isrotating slowly.
Fig. 2 is a similark cross-section for the position of the parts corresponding to higher speeds. A
Figs. 3 and 4 are similar views of another form of execution of my invention. n
On the several figures the same parts have been given the same reference numbers. On Figs. 1 and 2, 1 is the tubular body of the nozzle screwed at 2 inside the carburetor and provided at 3 with a calibrated hole at its lower inner end of said tube 11.
end. Inside the tube 1 may slide a second tube 5 provided atits lower end withy a flange 4 for limiting the travel ofthe slidable tube in each direction either at the stop 6 provided inside the tube 1 (position shown on Fig. 1) or at the 60 shoulder 7 .(position shown on Fig. 2). The tube 5 is provided moreover with a helical slot 8 which is uncovered gradually as the tube 5 projects further `beyond the tube 1.
The working is as follows: For small speeds of rotation the nozzle is as shown on Fig. yl. As the speed increases, the tube 5 rises gradually inside tube 1 under the action of the flow of gasoline and of the increasing suction. When the lspeed increases furthermore and the tube 5 continues to rise, the slot 8 is gradually uncovered and the flow of gasoline becomes greater: at the same time the fuel is well stirred up.
Thus the ilow of fuel .is automatically adjusted for every speed whereby the eiiioiency is in- 5 creased and the fuel may be economized to a great extent.
In the modification shown on Figs. 3 and 4, the tube 5 does not slide inside the tube 1 itself. At the top of the tubular body 1 is screwed a plug 10 held down by a ring 16. This plug shows a number of longitudinal bores 14 near its periphery and carries integrally therewith' a central tube 11 inside which may slide a movable tube 5l similar to that shown on Figs. l and 2. The movement of the tube 5 is arrested at each end through its flange 12 by the shoulder 7 ontube 11 and by a stop 6 screwed in the The movable tube, instead of showing a helical slot 8 is provided with a certain number of aperturesv 13, which are gradually uncovered as the tube passes out of the tube 11.
The working is similar to that described herein above with reference to Figs. 1 and 2.
At slow speeds, the tube 5 is in the position shown on Fig. 3. As the speed increases, the tube 5 passes gradually out of the tube 11 and at full speed comes into the position shown on Fig. 4. `Moreover the fuel does not only pass out of the tube 5 but also through the bores 14 `whereby the fuel is better atomized. The gasoline enters thus the nozzle through a single port vat its bottom and passes out through 10g multiple apertures forming a sort of watering pot spout.
Fig. 1 shows the nozzle positioned in a venturi shaped diffuser 17.
In practice I may obviously change the above mentioned details of execution in a great number of manners without passing out of the scope of the appended claims and the invention is by no means limited to the nozzles described hereinabove by way of example.
What I claim is:
1. In a carburetor provided with a venturishaped diffuser, the combination `of a nozzle body open at both ends, a tube also open at both ends provided with a lateral elongated opening towards its outer end slidably mounted in the body and stops inside the body adapted to limit the minimum and maximum amount by which the tube projects beyond the nozzle body into the carburetor venturi-shaped diffuser.
2. In a carburetor provided with a venturishaped diiuser, the combination of a nozzle body open at both ends, a tube also open at both ends provided with a lateral helical opening towards its outer end slidably mounted inthe body and stops inside the body adapted to limit the minimum and maximum amount by which the tube projects beyond the nozzle body into the carburetor Venturi-shaped diiuser.
3. In a carburetor provided with a venturisliaped diiiuser'the combination of a nozzle body, open at both ends, a tube also open at both ends, provided with at least one lateral opening towards its outer end, slidably mounted relatively to the body, and means for limiting the minimum and maximum amount by Whicli the tube projects beyond the nozzle body into the venturi-shaped diffuser.
4. In a carburetor provided with a venturishaped diffuser, the combination of a nozzle body open at both ends, a tube also open at both ends, provided with lateral openings, towards its outer end, slidably mounted inside the body, and means for limiting the maximum, and minimum amount by which the tube projects beyond the nozzle body into the venturi-shaped d'iuser.
5. In a carburetor provided with a venturishaped diffuser, the combination of a nozzle body open at both ends provided with several holes, and slidably mounted relatively to the body, the means for limiting the maximum and minimum amount by which the tube projects beyondthe nozzle body into the venturi-shaped diffuser.
6. A carburetor nozzle comprising a stationary tube open at botli ends, a plug fitted therein and provided with a plurality of longitudinal grooves, a central tube secured to the plug, av
perforated tube slidably mounted in the central tube and stops for limiting the travel oi' the slid-able tube in both directions.
