2 Claims. (Cl. 26139) This application is a continuation of my pending application Serial No. 184,787, filed April 3, 1962, now abandoned.
The invention relates to internal combustion engine carburetors comprising an auxiliary device to increase the fuel feed for cold starting conditions and abutment means for controlling the idling throttle opening, said abutment means being capable of increasing this opening for running with cold engine, said auxiliary device and abutment means being operated automatically in accordance with the temperature of the engine.
In my US. patent of November 5, 1963, No. 3,109,874, filed March 24, 1961, for Improvements in Carburetors Comprising an Auxiliary Device to Increase the Fuel Feed for Cold Starting Conditions, I described a carburetor in which the above mentioned abutment means consist of a thermostatic device comprising a material, contained in a closed housing, undergoing an important variation of volume when passing in a reversible fashion from one physical state to another one, and in particular from the solid state to the liquid state, between the temperatures to which said material is to be subjected according as the engine is cold or warm, respectively, such a device being capable of developing an effort greater than the force exerted by the resilient return means acting upon the throttle valve.
According to the present invention the carburetor is characterized by the fact that said thermostatic device acts not only upon the throttle valve but also upon the auxiliary starting device, this starting device consisting preferably of an unbalanced choke valve, i.e. a valve mounted on a shaft off-set from the center of induction pipe so that the air flow through this pipe will tend to open the valve against the resistance of resilient means.
Preferred embodiments of the present invention will be hereinafter described with reference to the appended drawings given merely by way of example and in which:
FIG. 1 is a diagrammatic elevational view, with parts in section, of a carburetor made according to the present invention;
FIG. 2 is a half-section view on the line IIII of FIG. 1;
FIG. 3 is a view similar to FIG. 1 showing the carburetor with its elements in the position corresponding to idling when the engine is warm;
FIG. 4 shows a modification of a detail of FIG. 1.
The general construction of the carburetor with the exception of the means for controlling the throttle valve idling position and the opening of the choke valve may be of any type. In the example shown by the drawings, the carburetor comprises an induction pipe 1 having at the top thereof an air inlet 2 in which is provided a choke valve 3 mounted on a shaft 4, this shaft being off-set with respect to the center of the induction pipe so that the air flow through said induction pipe will tend to open said valve. Downstream of said choke valve 3 are located, successively, in pipe 1, a venturi 5 and a cylindrical portion in which is mounted a throttle valve 6 carried by a spindle 7. Throttle valve 6 is opened by the driver through a throttle control 8 which acts, in the direction of the arrow of FIG. 1, upon a lever 9 fixed on spindle 7, the throttle valve being constantly urged toward its closed position by a spring 10. The primary mixture of air and fuel (not shown) opens into venturi 5.
The abutment means serving to determine the position of throttle valve 6 in idling position consist essentially of an oscillating lever 21 rotatable freely about spindle 7 and the lower part 21a of which cooperate with an element rigid with throttle valve 6. In the construction shown by the drawing, this element consists of a screw 22 mounted in a lug 23 rigid with spindle 7. Lug 23 may further carry, as shown, a second screw 34 which coopcrates with an abutment 35 rigid with the casing of the carburetor, this screw 34 serving chiefly to limit the minimum opening, corresponding to idling with the engine Warm, of throttle valve 6. The angular position of lever 21 and consequently the minimum degree of opening of throttle valve 6 are determined by a thermostatic device comprising a material 24 contained in a closed casing 25 and capable of undergoing a substantial variation of volume when passing in reversible fashion from one physical state to another one and in particular from the solid or pasty state to the liquid state between the temperatures to which it is subjected according as the engine is cold or warm. In order to transmit to the outside the effects due to the variations of volume of material 24, a push-piece 26 extends to the outside of casing 25. This casing 25 is fixed in a chamber 14 by a screw 36 which applies said casing against an annular packing joint 37.
Concerning now the control of choke valve 3 in accordance with the temperature of the engine it is ensured by thermostatic device 24-26 itself. For this purpose, choke valve 3 is urged in the closing direction by a return spring 39 secured to the upper end 21b of lever 21 so that the force exerted by this spring 39 upon choke valve 3 decreases when the temperature of material 24 increases and inversely.
As shown by FIGS. 1 to 3, spring 39 is secured to a lever 13 rigid with shaft 4. According to the modifica tion of FIG. 4, spring 39 is secured to a flexible strip or wire 40 which passes around a cam 41 rigid with shaft 4.
Finally, according to a known arrangement there is secured to the end of lever 13 (or cam 41) a rod 18 pivoted at its other end to a piston 17 slidable in a cylinder 42, this cylinder being connected through a pipe 16 to the portion of induction pipe 1 located downstream of throttle valve 6. A groove 20 and an orifice 19 opening into a groove of piston 17 permit of adjusting the displacement of piston 17 under the effect of the suction transmitted through pipe 16 when the action of spring 39 is sufliciently strong to prevent a full displacement of piston 17 toward the left (FIGS. 1, 3 and 4).
The carburetor such as above described works in the following manner. When the engine is cold (FIG. 1) push-piece 26 is wholly retracted with respect to its casing and spring 28a pushes lever 21 toward said push-piece so that the degree of opening of throttle valve 6 (determined by the cooperation of screw 22 with said lever) is relatively great. When the engine has warmed up (FIG. 3) push-piece 26 is driven outwardly and pushes lever 21 toward the left against the action of spring 28a so that the degree of opening of throttle valve 6 for idling running is reduced.
On the other hand, when the engine is cold the pivoting of lever 21 toward the right increases the pull exerted through spring 39 on choke valve 3. This produces, other things being equal, a greater closing of choke valve 3 and therefore a greater suction downstream of this choke valve and finally a greater feed of fuel into venturi 5. The characteristics of spring 39 and the shape of cam 41 (if such a cam is used, according to FIG. 4) are determined in such manner that the law of variation, as a function of the temperature, of the force tending to close choke valve 3 is in accordance with the requirements for satisfactorily starting the engine from cold.
As soon as the engine is started, piston 17 is driven toward the left of FIG. 1 by the suction transmitted through pipe 16 and this displacement is limited by the communication opened between groove 20 and orifice 19. The length of groove 20 is calculated so that the degree of opening of choke valve 3 in these conditions corresponds to the running of the engine when cold.
As thermostatic device 24-26 is being more and more heated, lever 21 pivots toward the left and, as above explained, gradually moves throttle valve 6 toward the idling running position suitable when the engine is warm. At the same time, the end 21b of lever 21 moves towards the left and thus reduces the pull exerted by spring 39 which enables choke valve 3 to open to a greater degree either under the effect of the air stream indicated by the arrow of FIG. 2 or through the action of piston 17 which has a tendency to move towards the left.
When the engine, and consequently thermostatic device 24-26, are sufficiently warm, the pull exerted by spring 39 is practically zero for the position of complete opening of choke valve 3. At the same time screw 34 has come into contact with abutment 35 and this limits the opening of throttle valve 6 to the minimum corresponding to idling running when the engine is Warm, whereas the portion 21a of lever 21 can move away from screw 22 and take the positions imparted thereto by pushpiece 26.
As soon as screw 34 has come into contact with abutment 35 (FIG. 3), the position of lever 21 no longer has any action upon throttle valve 6 and on the other hand it no longer influences the force tending to close choke valve 3.
The law of variation of this force as a function of the angular position of choke valve 3 depends, in the construction of FIGS. 1 to 3, upon the angle made by lever 13 with the longitudinal axis of spring 39 and in the case of the construction of FIG. 4 upon the shape of cam 41, the construction of FIG. 4 permitting a more accurate adjustment of said variation.
The above described embodiment of the invention is given merely by way of example.
