摘要： An accelerator pump cap (30, 70, 100, 150) for an accelerator pump assembly of a carburetor, such as a motorcycle or ATV carburetor, has a cap body (30, 70, 100, 150) with a base (38, 80) and a sidewall (56, 78, 104, 154) projecting from the base (38, 80) defining a fuel chamber (44, 102, 152) within the cap body (30, 70, 100, 150) beneath an open top. Preferably, one or more outlet ports (60, 72, 112, 160) extend through the sidewall (56, 78, 104, 154) closely-spaced to the open top of the cap body (30, 70, 100, 150) to ensure that any vapor or gas residing within the fuel chamber (44, 102, 152) is flushed out of the fuel chamber (44, 102, 152) through the outlet ports (60, 72, 112, 160) when the accelerator pump assembly is actuated to supply fuel to the carburetor. Accelerator pump assemblies and the use of a separate collector ring (90, 120, 140, 170) within an accelerator pump cap are also provided.

摘要： 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.

摘要： 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).

摘要： 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.

摘要： 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.

摘要： 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).

摘要： An accelerator (28) having a main body defining a main chamber, a movable member (e.g., a diaphragm (34)) positioned within and dividing the main chamber into a pneumatic chamber (36) and a fuel chamber (38), and a damping orifice (62) (e.g., in the main body) interconnecting the pneumatic chamber (36) with a gas source (e.g., ambient air). The damping orifice (62) has a cross-sectional area less than about 0.002 square inches. To inhibit contamination of the accelerator, a filter (64) can be operatively positioned between the pneumatic chamber (36) and the ambient air.
