摘要： A feedback type variable venturi carburetor in which the negative pressure regulated by the variable venturi at a constant level is supplied to a solenoid valve which is opened and closed at a frequency of 5-30 Hz and whose open-close time ratio is controlled in accordance with the signal from exhaust gas sensor to control the vacuum pressure applied to a diaphragm chamber of an air-bleed flow control means thereby controlling the air-fuel ratio of the mixture at an optimum level. This invention obviates the use of a regulator for regulating the negative pressure from the intake manifold and precludes the drawbacks experienced with conventional carburetors, such as the slow response in the feedback control caused when the main fuel system and the idling system of the conventional carburetor are switched over, and the unstable supply of fuel when the fuel begins to be delivered from the main fuel system.

摘要： A variable venturi-type carburetor comprising a vacuum chamber and an atmospheric pressure chamber which are separated by a suction piston. A needle is mounted on the central portion of the tip face of the suction piston. A suction hole, interconnecting the vacuum chamber to a venturi portion of the carburetor, is formed on the tip face of the suction piston at a position located upstream of the needle. The vacuum chamber is open to the atmosphere via a flow rate control valve apparatus when the engine temperature is low. The vacuum chamber is disconnected from the atmosphere by the flow rate control valve apparatus when the engine temperature is high.

摘要： A variable venturi-type carburetor comprising a suction piston, a fuel passage, and a needle fixed onto the suction piston and extending through the fuel passage. An air bleed passage is connected to the fuel passage. During engine starting, before the engine begins to rotate by its own power, the vacuum chamber of the suction piston is open to the atmosphere and the air bleed passage is shut off. When the engine begins to rotate by its own power, the vacuum chamber of the suction piston is closed from the atmosphere. After this, the air bleed passage is gradually opened. Such control of the closing of the vacuum chamber and the opening of the air bleed passage prevents engine stall by preventing the fuel mixture from becoming excessively lean when the engine first begins to rotate on its own power and then prevents engine misfires by subsequently reducing the air-fuel ratio to a lean mixture.

摘要： A variable venturi type carburetor having a suction piston movable in response to the intake air flow rate to maintain a substantially constant flow velocity at a venturi portion defined between itself and the opposing wall of the carburetor body, the suction piston being provided at its bottom with a pair of partition plates having exponential, arcuate or tapered end surfaces, in order to suppress self-excited oscillation of the suction piston. The pair of partition plates being opposed by a bridge formed on the wall of the carburetor body to form therebetween a diverging opening. The distance between the pair of partition plates and the bridge is independently adjustable to make it possible to maintain a desired size of gap to avoid the fluctuation of fuel metering characteristics.

A raised wall is formed on the inner wall of the intake passage, which faces the tip face of the suction piston. The raised wall has a substantially straight extending tip edge. The inner wall of the intake passage and the tip edge of the raised wall define a D-shaped air inlet mouth. The connecting portions of the inner wall of the intake passage and the tip edge of the raised wall have an arc shape. The upstream end portion of the tip face of the suction piston and the tip edge of the raised wall define an isosceles triangular air inlet opening therebetween when the amount of air fed into the cylinder of the engine is small.

摘要： A floatless variable venturi type carburetor in which the float chamber is substituted by a fuel pressure regulator. The carburetor has, in addition to the ordinary constituents such as variable orifice, fuel metering jet and air bleed, a fuel valve disposed in the fuel passage leading to the fuel metering jet and adapted to be opened and closed in relation to the turning on and off of the engine key switch, and a fuel pressure regulator adapted to regulate the pressure of the fuel introduced to the fuel metering jet through the fuel valve. The fuel pressure regulator has two regulating chambers, one of which being communicated with the inlet side of the fuel valve while the other being in communication with a venturi vacuum pickup port, so that the fuel pressure regulator maintains a constant pressure differential, by the action of a diaphragm separating two regulating chambers, between the fuel pressure at the inlet side of the fuel metering jet and the venturi vacuum. The fuel pressure regulator also is so constructed that its valve mechanism constitutes a part of a fuel return passage to a fuel tank. The carburetor is advantageously incorporated in a feedback system for controlling the air-fuel ratio of the mixture formed in the carburetor, the system having an exhaust gas sensor disposed in the exhaust system of the engine, a control circuit adapted to produce a control signal in response to the output from the exhaust gas sensor, and an actuator adapted to operate in response to the control signal, and means for varying the opening area of the air bleed in response to the operation of the actuator.

摘要： A variable venturi type carburetor incorporating a changeover valve which conducts the fuel vapor in the float chamber either into the internal passage leading to the suction pipe of the carburetor or into the external passage leading to the canister. The changeover valve is actuated via a rod projecting into the intake passage by a suction piston which is displaced according to the amount of air drawn into the engine and which abuttingly contacts the rod. With this invention, an electromagnetic valve employed in the conventional carburetor can be obviated and the structure of the carburetor becomes simple and small.
