Abstract: A diaphragm carburetor with both the main metering nozzle and an idle circuit supplied with liquid fuel from the same metering chamber and an accelerator and shut-off assembly in the idle circuit. The assembly has a valve which is open to supply fuel to the idle circuit when the throttle is in a closed idle position and closes off the supply of fuel from the metering chamber as the throttle is moved to its wide open position. Opening of the throttle also actuates a piston to supply additional fuel for accelerating an engine.

Abstract: An improved fuel bowl assembly adapted to be detachably mounted upon a main carburetor body minimizes exposure of sealing gaskets to standing heads of fuel contained in the bowl and affords ready access to the interior of the bowl without risk of fuel spillage. A one piece housing is formed with a bathtub-like fuel bowl chamber whose open top is closed by a detachable cover. The front wall of the housing is provided with fuel and air bleed passages so arranged that fuel flowing from the bowl through these passages must rise above the normal level of fuel maintained in the bowl before exposure to the gasket which seals the front surface of the front wall of the housing to the side of the main carburetor body. A float valve mounted on the bottom side of the cover controls the flow of fuel from an inlet passage in the cover to maintain a desired level of fuel in the bowl, and the moving parts of an accelerating pump are also mounted on the cover. Thus, removal of the cover provides complete access to the float valve, accelerating pump and the interior of the bowl without requiring detaching the bowl assembly from the main carburetor body.

Abstract: Several embodiments of charge forming devices embodying enrichment circuits that provide enrichment substantially only when the engine is running above its idle speed and below a predetermined slow speed so as to improve running without excessive fuel consumption under high speed conditions. In each embodiment, the enrichment circuit includes a port in the induction passage upstream of the idle position of the throttle valve and which is served by a fuel well. In accordance with one embodiment of the invention, the discharge of the enrichment circuit is controlled by a throttle valve position responsive valve. In this embodiment, the throttle valve position responsive valve may comprise the pumping element of the accelerating pump. In other embodiments of the invention, the discharge of the enrichment circuit is controlled by providing restricted communication between the fuel source and the enrichment fuel well.

Abstract: A fuel feed system adapted to maintain at a constant value the pressure difference across a fuel measuring gate disposed in a fuel feed passage and control the area of opening of the fuel measuring gate in connection with the amount of air being sucked into an internal combustion engine so as to continuously measure the fuel, the measured fuel being concentratedly injected at a positive pressure into the suction pipe. The system comprises an accelerator pump interlocked to a throttle valve for injecting fuel at a positive pressure into the suction pipe during acceleration. The accelerator pump is fed with fuel sucked up from the return pipe of a pressure regulator which feeds the fuel measuring gate with fuel at a predetermined pressure.

Abstract: A carburetion arrangement and method of carburetion for a multicylinder internal combustion engine wherein at least one carburetor acts as a main mixture forming device with the main mixture being guided through individual intake lines which connect the carburetor to intake valves of the engine. Further mixture components are guided through separate air and fuel lines which terminate in the individual intake lines with the separate air and fuel lines being combined immediately before the intake lines. The intake air is supplied to the further mixture components primarily through the individual intake lines with a volume controlled portion of the intake air of this mixture component, reduceable to zero, being guided through the separate air lines, as correction air for the fuel to the mixture components flowing through the separate fuel lines. The correction air flowing through all the lines is controlled volumewise by a common control device which is disposed upstream of an air distributor for the air lines. The fuel is fed to the separate fuel lines commonly and at zero pressure from the carburetor as well as to individual inlets in the respective intake lines by way of a fuel throttle nozzle located in a vicinity of the individual inlets.

Abstract: A carburetor for internal combustion engines with an acceleration pump whose pump chamber is connected to the float chamber by a suction duct having a suction valve. The pump chamber also is connected to the intake line section upstream of the throttle by a delivery duct having a pressure valve and a calibrated injection opening. The acceleration pump has a displacement member which is actuated via a linkage by a lever depending on the throttle position. The pump chamber has a flow duct, leading to the float chamber and having a cross section adjustable by means of a screw, and a second adjustable flow duct whose inlet has a valve actuated by the throttle position. The valve may have a spring which presses a closure member, held in a diaphragm, against the inlet overcoming the force of the fuel pressure. This spring also presses a plunger against a second lever arm which actuates the acceleration pump.

Abstract: A fuel valve that is urged toward its seat by gravity is located in the discharge passage of a carburetor accelerator pump and separates the discharge passage from an outlet passage communicating directly with the carburetor induction passage. An air vent is provided for the outlet passage and a check valve located in the air vent also is urged toward its seat by gravity. During accelerator pump operation, the air vent check valve remains on its seat and fuel flows into the carburetor induction passage. If a low pressure develops in the outlet passage, the pressure differential lifts the air vent check valve from its seat before the fuel valve is lifted from its seat and thereby prevents spurious fuel flow through the accelerator pump system.
