    Abstract: An accelerated fuel passage of an accelerator pump operatively connected with a throttle shaft having a throttle valve. The accelerated fuel passage is connected to an upstream side of a needle orifice, which orifice is coupled to a main nozzle. Consequently, the fuel is discharged by the accelerator pump into an area before the needle orifice. By the addition of a one-way check valve system in a fuel pick up at a metering chamber for a fuel circuit, the fuel driven by the accelerator pump piston is discharged to a venturi tube of an intake passage through the main nozzle. A self pumping effect caused by an engine pulsation is dampened or eliminated by the needle orifice. Further, a check valve is provided within a fuel pick up at a metering chamber for a fuel circuit, whereby the fuel driven by the accelerator pump piston is discharged to a venturi tube through a main nozzle without returning to the fixed fuel chamber.

    Abstract: An accelerator for a carburetor that is linked to a throttle valve and allows a piston-type accelerator pump to be operated in a simple configuration that dispenses with a link mechanism and does not greatly enlarge the carburetor. The lower surface of a throttle valve lever (10) is provided with a cam (33) that has a circular shape centered about a throttle valve stem (8) and is configured such that the cam surface (33A) thereof faces a carburetor main body (1). An accelerator pump (25) is placed parallel to the throttle valve stem (8) and the upper end of a piston rod (28) thereof is brought into contact with the cam surface (33A). The cam (33) pushes the piston rod (28) down as the throttle valve lever (10) swings in the opening direction of the throttle valve, and the acceleration fuel in the pump chamber (29) is delivered and supplied to the suction channel (2).

    Abstract: A method and device for increasing the amount of fuel to an engine during acceleration is provided. A secondary source of fuel in addition to a first source of fuel is introduced into the engine during acceleration. The secondary source of fuel is introduced through a secondary fuel delivery line which is opened by a valve actuated in response to throttle control movement. In a first embodiment, the secondary fuel delivery line communicates with a fuel delivery area from which fuel is supplied to the first fuel source. The valve is pressed open by the throttle control along with a primary fuel source needle valve control, allowing fuel from the fuel delivery area to flow through the second fuel line in addition to the first fuel source. In second and third embodiments, the secondary fuel line communicates with an excess fuel return line. A valve extends across the fuel return line and secondary fuel line. The valve is movable between a closed position in which the fuel return line is open and the secondary fuel line obscured, and an open position in which the fuel return line is blocked and fuel is diverted to the secondary fuel line. In the second embodiment, the valve is moved by a control rod connected to a rotatable linkage connected to the throttle control. In the third embodiment, the valve is opened by movement of a vacuum operated diaphragm device.

    Abstract: A small engine carburetor with manually controlled choke and throttle valves and associated idle ports and main metering nozzle supplied with fuel from a common metering chamber. The A/F is automatically adjusted by a solenoid operated poppet valve and/or gear driven needle valve and cooperative electronic control circuitry and system components built-in to the carburetor. A combined accelerator pump and idle circuit shut-off mechanism is also built-in and mechanically operated by the throttle shaft so that only the main nozzle supplies fuel when the engine is running above fast idle. A mechanical choke/throttle interlock mechanism also prevents partial choking when the engine is running above fast idle, and throttle operation above fast idle when choking. An electric motor worm gear drive unit controlled by the automatic system is detachably coupled to, and provides fine incremental adjustment of, the main metering needle and is self-locking to retain set adjustment during engine running and at engine shut-off. Control system components are arranged in a compact overall package characterized by a laterally offset, skewed orientation of control box and carburetor body, with a diaphragm fuel pump and metering chamber sharing box and body for intercooling of electronic and electrical components by incoming fuel while assisting fuel vaporization in the carburetor venturi passage.

    Abstract: A carburetor with a main fuel jet and a throttle valve in a mixing passage and an apparatus for automatically supplying an enriched fuel and air mixture when an engine is cranked for starting and initial running of the engine upon starting. The apparatus has a mixing chamber with an air intake passage communicating with the mixing passage upstream of the throttle valve, a fuel inlet passage, and an outlet passage for the fuel and air mixture which communicates with the mixing passage downstream of the throttle valve. A valve for controlling the flow of the enriching fuel and air mixture through the outlet passage is manually movable to its opened position where it is releasably retained by an actuator mechanism operably associated with the throttle shaft for releasing and closing the valve when after the engine starts the throttle valve is initially moved from its idle position toward a full open position of the throttle valve.
