Abstract: Several embodiments of charge forming devices including improved accelerating pumps wherein the discharge of fuel from the accelerating pump is extended in time through the use of an accumulator chamber. In addition, the accelerating pump has an upstream and downstream discharge port. The accumulator chamber is also adapted to discharge fuel into the induction passage during extreme deceleration so as to improve engine running and prevent stalling under these circumstances.

Abstract: The invention relates to an apparatus for supplying fuel for acceleration during the warm-up phase of an internal combustion engine. The fuel supplied downstream of an arbitrarily actuatable throttle butterfly valve located in the induction tube of the engine being in addition to the fuel supplied by a fuel supply system. There is disclosed a motion control means which is associated with the butterfly valve and actuated thereby upon opening of this valve. The motion control means further includes electrical contacts disposed in an electrical circuit, electromagnet means in the circuit and other valve means arranged to be controlled by said electromagnet for feeding fuel into said induction tube downstream of said butterfly valve upon closing of said contacts. There are several variants of the control means; one constituted by a flexible bellows and the other by a dash pot.

Abstract: A carburetor comprises a mixture outlet and a connection for attaching the mixture outlet to an intake manifold. A main air intake is spaced from the mixture outlet and has a butterfly valve adjustable to control the flow of air into the carburetor. The carburetor also has a fuel inlet. A pair of spaced apart surfaces forms a fuel path from a central portion of the spaced apart surfaces to the periphery of the surfaces. The periphery is adjacent to the carburetor passageway for enabling air from the main air inlet to mix with the fuel and pass to the intake manifold. A central fuel inlet forms a path for fuel from the carburetor fuel reservoir to the surfaces central portion. The central fuel inlet comprises an elongated axially movable tube whose outer surface is tapered. A cylindrical member has its inner surface surrounding the elongated tube outer surface. The cylindrical member and the tube when spaced apart define a main fuel path from the fuel reservoir to the central portion of the surfaces. A secondary air inlet forms an air intake passageway when the main air inlet is closed. The secondary air inlet is defined by a first bore formed in the interior of the elongated tube extending from the carburetor exterior adjacent the main air intake to the central portion of the surfaces. A secondary fuel inlet forms a fuel inlet passageway for mixing with the air in the secondary air inlet. The secondary fuel inlet comprises a second bore in the elongated tube which extends from the fuel reservoir to the central portion of the surfaces. At least one orifice communicates with the bores at the central portion surfaces. A needle is movable with respect to the elongated tube in the first bore for adjusting the flow of the air-fuel mixture through the orifice.

Abstract: Lever and linkage mechanism are disclosed for staged or sequential operation of the accelerating pump of a two-stage carburetor. The linkage mechanism is so arranged that the accelerating pump is caused to travel during an initial opening of the primary valve of the carburetor, after which the pump ceases to move until the secondary throttles begin to open, at which time additional pumping action is accomplished by the accelerator pump.

Abstract: A carburetor for an internal-combustion engine, equipped with an accelerator-controlled butterfly valve in a mixing channel, has a first fuel-injection nozzle downstream and a second fuelinjection nozzle upstream of that valve, each of these nozzles opening into the channel in the immediate vicinity of a respective high-pressure duct serving to atomize the injected fuel. The atomizer duct for the first nozzle is unblocked under low-load conditions (idling) by a diaphragm-controlled valve responsive to the suction prevailing in the channel beyond the closed butterfly valve. The second nozzle, supplied by an ancillary fuel pump under the control of the accelerator under high-load conditions (kickdown), may have its atomizer duct connected to an air-pressure accumulator which is charged at low load by the pressure differential developed across the butterfly valve.

Abstract: The invention comprises a carburetor having a controller in the fuel line feeding the main carburetor venturi to seal the fuel system against evaporative losses. The controller comprises two diaphragm operated valves arranged in cascade series. A throttleactuated pump is also provided to operate the diaphragms to open the valves simultaneously and quickly for fast acceleration.
