Definitions

  • Another object of the invention is to provide acaburetor in which the richness of the mixture is increased during operation under heavy load or at high speed.
  • Figure 1 is a central section with parts in elevation of a carburetor embodying the invention
  • Figure 2 is an enlarged partial view of the carburetor of Figure 1:
  • Figures 3 to 6 are views similar to Figure 2 showing various modified constructions.
  • a carburetor including a downdraft conduit I constricted at I2 to form a venturi and connected at its lower end to an engine manifold I4.
  • the carburetor is provided with the' usual choke and throttle valves I6 and I8 and has a fuel chamber 20 formed around the conduit I0 receiving fuel fr ⁇ om a passage 22 leading to any suitable source under the control of a float operated valve 24.
  • Fuel from the chainber 20 is supplied to a stream of air flowing through the conduit I0 by a main nozzle 26 opening at its lower end through a meteringrgic into the lower part of the fuel chamber and discharging into an auxiliary venturi 28 which is mounted in the conduit I0 substantially at the throat of the main venturi I2.
  • a pump cylinder 30 communicating at its upper end with the top of the fuel chamber and having an inlet 32 provided with a check valve connecting its lower end to the lower part of the fuel chamber.
  • a piston 34 is slidably mounted in the cylinder 30 and is formed with a central'vent closed by a float valve 36. If any vapor collects in the pump cylinder the valve 36 will open to permit its escape through the vent in the piston but as the liquid rises the valve 364 will float to closed position to prevent its escape.
  • 'I'he piston 34 is connected, by a lost motion connection indicated at 31, to a rod 38 operated by 'an arm 40 which is connected through suitable linkage, not shown, to the throttle valve It so that when the throttle is opened the rod will be moved down.
  • a spring 42 urges the piston 34 down and tends to maintain a continuing pump discharge within the limits of the lost motion connection as the throttle is opened.
  • Fuel from the cylinder 30 discharges past a tapered valve 44 into an annular chamber 46 which communicates with a chamber 48 closed on one side by a flexible diaphragm 50.
  • the valve .44 is connected directly to the diaphragm 50 which is connected on its other side to the conduit IIl posterior to the throttle by a pipe 52 to be responsive to the suction therein.
  • a spring 54 in the chamber 46 urges the valve 44 off its seat in opposition to the suction on the diaphragm 50 and the valve 44 is formed with a by-pass controlled by a check valve 56 to permit discharge of fuel from the pump cylinder celeration.
  • the amount of fuel supplied is proportional to the amount of throttle opening and is continued as long as opening movement of the throttle continues.
  • a difficulty with acceleration pumps of known types has been that at low engine speeds with small throttle opening, a relatively small amount of throttle movement will provide a full air charge to the engine but will not operate the pump sufficiently to provide a full fuel charge.
  • suction jon the diaphragm 5I decreases allowing the diaphragm to move up under the influence of spring 46 to force fuel from the chamber 48 through the nozzle 58 to provide a full fuel charge.
  • Suction on thediaphragm 50 will also drop if a load isA applied to the engine without moving ythe throttle and under these conditions the diphragm will also operate as ayvacuum controlled fuel pump to increase the fuel charge.
  • the combination of the throttle operated pump and vacuum pump provides an accelerating charge of fuel under all conditions when it is desired.
  • the valve 44 controlled by the diaphragm 50 also serves to increase the fuel charge when there is a full air charge (low suction) by slightly raising valve 44 from-its seat to open a passage from the fuel chamber to the nozzle 5B.
  • the valve 44 will open and fuel will flow from the fuel chamber chamber 46 and passage 55 into the nozzle 58 to increase the fuel charge. to the engine.
  • Flgurel 3 illustrates a slight modification of the structure of Figure 1 in which the piston 34 is replaced by a diaphragm 35. Otherwise the structure and operation are the same and parts corresponding to like parts in Figure 1 have been indicated by the same reference numerals.
  • FIG 4 shows another carburetor embodying the invention, parts therein corresponding to like parts in Figures 1 and 2 being indicated by the same reference numerals plus

  • connects the pump cylinder to -the space below plunger
  • 51 closed is weaker than that closing the valve
  • 34 carries a bracket 62 having a split end straddling the piston rod
  • thev bracket will force plunger
  • FIG. 5 illustrates another embodiment of the invention, parts therein corresponding to like parts in Figure 4 being indicated by the same reference numerals plus 100.
  • the economizer valve 244 is placed in the lower part of the pump cylinder 230 with its end projecting into that cylinder to be engaged by the piston 234.
  • the economizer valve also serves as a pump outlet check valve and the discharge from both the mechanical pump 234 and the vacuum' pump 25
  • the operation of this embodiment is similar to that of Figures 1 and 2 except that the economizer valve is operated by the throttle and it represents a simplification of the form shown in Figure 4 with omission of certain of the functions.
  • FIG. 6 illustrates still another embodiment of the invention, parts therein corresponding to like parts in Figures 1 and 2 being indicated by the same reference numerals plus 300.
  • a housing part 366 formed with a cylindrical extension is secured to the fuel chamber clamping the diaphragm 350 between them.
  • 'I'he diaphragm is not connected to the economizer valve 344 but is adapted to engage a stem thereon to open the valve.
  • a sleeve 368 is slidably mounted in the part 366 and has a lost motion connection with a rod 310 which is connected to the diaphragm 350, a spring 312 urging the rod and diaphragm to the limit of their travel in the downward direction away from the valve 344.
  • the sleeve 368 carries a second rod 314 which is connected through a lost motion connection to a yoke member 316, a spring 318 urging the yoke member away from the sleeve.
  • the yoke member is connected to one arm of a bell crank lever 380, the other arm of which is connected through a link 382 to a lever 384 which is carried by the throttle valve shaft.
  • the valve 344 controls ow of fuel through a passage 341 into the main nozzle above the metering orifice.
  • auxiliary nozzle 358 communicates with the chamber 348 past a check valve 351 which is urged onto its seat by a spring weaker than the spring urging the valve 344 closed so that in normal pumping operation fuel will be discharged past the valve 351 through the auxiliary nozzle.
  • the diaphragm moves far enough it will engage and open the valve 344 to increase the supply of fuel to the main nozzle.
  • the diaphragm 350 is responsive y to variations in suction within the limits permitted by the lost motion connection between sleeve 368 and rod 310 and also to movements of the throttle.
  • the lost motion connection is so arranged that when the throttle is closed substantially no movement of the diaphragm is permitted, when the throttle is only slightly open the diaphragm can move but not enough to open valve 344 and when the throttle is in the normal operating range the diaphragm is substantially free to move in response to variations in suction in much the same manner as described in connection with Figure 4.
