Abstract: A system for automatically adjusting the diffuser and gasoline passage sections of carburetors. During acceleration, the passage section of the diffuser (5) is increased gradually simultaneously with the opening of the throttle valve, and a needle valve (3) for the inlet of gasoline to the nozzle is opened. A gasoline overfeed valve (43) is activated to initiate acceleration, which activation is interrupted at successive positions of the accelerator. Said overfeed valve is also activated when starting a cold engine by pulling the starter, closing its throttle valve and partially opening the acceleration valve, with the consequent increase in the diffuser and gasoline passage sections.

Abstract: In at least some implementations, a carburetor includes a body, a fuel pump diaphragm and a pressure pulse passage. The fuel pump diaphragm is carried by the body and defines in part a fuel chamber on one side of the fuel pump diaphragm and a pressure pulse chamber on the other side of the fuel pump diaphragm. The pressure pulse passage communicates the pressure pulse chamber with a pressure pulse source to provide pressure pulses in the pressure pulse chamber to actuate the fuel pump diaphragm. The pressure pulse passage includes an inlet communicating with a passage in which pressure pulses are present and the inlet is spaced from a surface defining the passage in which pressure pulses are present.

Abstract: A carburetor provides a supplemental fuel supply to an engine and includes a body, a fuel metering diaphragm and a fluid pump. The fuel metering diaphragm defines part of a fuel metering chamber and a reference chamber and has at least a portion that is movable relative to the body to increase and decrease the volume of the fuel metering chamber to control fuel flow in the fuel metering chamber. The fluid pump is carried by the carburetor or another component upstream of the carburetor and has an outlet in fluid communication with the metering reference chamber and an actuator arranged to discharge fluid through the outlet to increase the pressure within the metering reference chamber and thereby increase the fuel flow rate from the fuel metering chamber to the air-fuel passage to provide a supplemental fuel supply to the engine.

Abstract: The system has detectors (2,74,76) detecting operating state to decide whether the engine is stationary or starting or in full detonation and able to keep rotating by itself. A control (60) controls the drive of the fuel supply pump (30) via a driver (58). The control has a circuit that determines the periods of the pulses applied to the pumps solenoid (56) in accordance with the operating state of the engine as determed by the detectors. The control also has a correction circuit for the pulse width such that the pulse applied to the solenoid is longer when the engine is starting than many other state.

Abstract: Disclosed is an engine fuel supply apparatus which can be made smaller in size and in which the amount of fuel in an air-fuel mixture (13) can be increased with a fast response in correspondence with the operation of a throttle valve (23) when the engine (14) is accelerated rapidly. The fuel supply apparatus is provided with a fuel booster pump (16). A portion of an air-fuel mixture is introduced into a negative-pressure chamber (65) of the fuel booster pump via a negative-pressure chamber channel (38), and the fuel booster pump is actuated. The actuation forces air in a pump chamber (66) to flow into a pressure chamber (27), and fuel (12) in a fuel storage chamber (26) is temporarily supplied to a carburetor (11).

Abstract: A carburetor for an internal combustion engine with an accelerator fuel pump in the carburetor having a piston actuated by a cam on a throttle valve shaft and a ball between them. The axis of a pump chamber in which the piston is slidably received is offset from and eccentric to the axis of rotation of the throttle shaft so that little fuel is supplied to the operating engine by the accelerator pump as the shaft is rotated to move the throttle valve from its idle position to an intermediate position and most of the fuel supplied by the accelerator pump to the engine is delivered as the shaft is rotated to move the throttle valve from the intermediate position to its wide open throttle position. This provides a proper fuel mixture to the engine to accelerate it and avoids the problem of supplying an overly rich fuel mixture to the engine during acceleration and particularly if the operator moves the throttle valve several times back and forth between the idle and intermediate positions before moving the throttle valve to the wide open position to accelerate the engine.

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.

Abstract: An injection molded plastic turbine rotor (16a) for a rotor-type carburetor is assembled by simply pressing together upper and lower generally cylindrical sections (50a, 52a). When joined in this manner the two sections (50a, 52a) form in the assembled rotor (16a) an internal circumferential seal (92a) between the two sections (50a, 52a), and an internal passageway system (120a, 122a', 124', 126a) which defines a centrifugal pump mechanism within the turbine rotor (16a). In an alternate embodiment, the rotor includes a third plastic section (160) which is captively retained within the rotor (16a), between the upper and lower sections (50a, 52a) thereof, and is adapted to lockingly receive an end portion of a fuel supply tube (32a) inserted downwardly through a central opening (58a) formed through the upper section (50a).
