摘要： The position of the metering rod relative to the slide member of a carburetor is adjusted by rotation of an adjusting screw which slidably extends through an opening in a plate member fixedly mounted within a substantially vertical bore in the slide member. The upper end of the adjusting screw has an enlarged head in engagement with the upper surface of the plate member and is engageable with a suitable tool to rotate the adjusting screw. The lower end of the adjusting screw is threadably received within a threaded bore in the head portion of the metering rod which is slidably and nonrotatably received within the bore in the slide member. A helical spring member surrounds the adjusting screw and is disposed between the lower surface of the plate member and the head portion of the metering rod to urge the metering rod downwardly. Accordingly, rotation of the adjusting screw causes the metering rod to move upwardly or downwardly so as to vertically adjust it relative to the slide member.
摘要翻译：计量杆相对于化油器的滑动构件的位置通过调节螺钉的旋转来调节，该调节螺钉可滑动地延伸穿过固定地安装在滑动构件中的基本垂直孔内的板构件的开口。调节螺钉的上端具有与板构件的上表面接合的扩大的头部，并且可与合适的工具接合以旋转调节螺钉。调节螺钉的下端螺纹地容纳在计量杆的头部中的螺纹孔内，其可滑动地且不可转动地容纳在滑动构件的孔内。螺旋弹簧构件围绕调节螺钉并且设置在板构件的下表面和计量杆的头部之间，以向下推动计量杆。因此，调节螺钉的旋转导致计量杆向上或向下移动，以便相对于滑动构件垂直调节。

摘要： A carburetor of the slide and metering rod type is characterized by the provision of an air deflecting bar in the carburetor throat adjacent the metering rod for deflecting the flow of air from the inlet end of the carburetor around the metering rod to reduce turbulence and increase air velocity by compressing the air flow. The deflecting bar has a wedge configuration with the pointed edge thereof facing in the direction of the inlet end. The bar may be permanently mounted within the throat or connected with the carburetor throttle slide member.

摘要： A carburetor comprising a body defining a throat, a throttle slide member slidably mounted on the body and disposed in the throat, and a tapered metering rod or needle mounted on the slide member and extending downwardly into a fuel supply tube leading into a fuel reservoir or bowl secured to the body. The slide member has front and rear, substantially flat panels disposed in substantially parallel relation, with the front panel being shorter than the rear panel for the purpose of providing air at the outlet of the fuel supply tube even when the slide is in a closed position and for directing air toward the outlet when the slide is in an open position. The body is provided with a substantially axial groove intersecting the fuel outlet at the throat for the purpose of directing high speed air flow toward the metering rod and over the fuel outlet when the slide is opened. The metering rod is provided with a downwardly and inwardly tapered, rear flat face and is mounted for longitudinal adjustment relative to the slide member.

摘要： A carburetor of the slide and metering rod type is characterized by the provision of a device for obstructing reverse or backflow air from the outlet end of the carburetor body from passing the metering rod in order to prevent the backflow air from contaminating or from drawing excess fuel into the air/fuel mixture. The obstruction device may comprise either a flanged tubular collar arranged within the outlet end or a tapered surface of an insert arranged adjacent the carburetor throttle slide member. Alternatively, the body may comprise a plurality of rearwardly and inwardly extending recesses near the outlet end thereof for preventing the flow of contaminated backflow air past the metering rod. Openings may be provided in the obstruction devices for reverting the backflow air into the flow of the air/fuel mixture rearwardly of the metering rod and toward the outlet end of the carburetor.

摘要： A carburetor of the slide and pin type having a throttle slide carrying a pin extending into a fuel discharge nozzle tube. The pin is tapered and has a shoulder at the deeper end of the taper which acts as an acceleraor pump, providing a spurt of fuel under conditions of rapid acceleration. The pump structure also provides support for the outboard end of the pin. A novel pin taper construction is also shown which furnishes increased atomization.

摘要： A carburetor for an internal combustion engine including a body having an air inlet opening and air outlet opening. A throat is disposed in the body between the air inlet and outlet openings. A slide assembly is movably disposed in the body for crosswise movement across the throat. The slide assembly includes a stepped portion upstream of the throat and the lower portion of the air inlet opening is narrowed for concentrating and compressing the air entering the throat. A reservoir containing fuel is attached to the body. The fuel reservoir includes a fuel outlet located in the throat. An adjustable metering rod extends through the slide assembly and throat into the fuel reservoir. A recessed scoop is located in the body above the air inlet opening and is in air flow communication with the fuel reservoir. An air supply tube extends from the scoop to the fuel reservoir and is provided with a cone-shaped cavity and float ball therein to prevent the flow of fuel into the air supply tube if the fuel level rises in the reservoir.

摘要： A carburetor comprising a body defining a throat, a throttle slide member slidably mounted on the body and disposed in the throat, a rotary actuator for the slide member, and a tapered metering rod or needle mounted on the slide member and extending downwardly into a fuel supply tube leading into a sealed and pressurized fuel reservoir or bowl secured to the body. The slide member has front and rear, substantially flat panels disposed in substantially parallel relation, with the front panel being shorter than the rear panel for the purpose of providing air at the outlet of the fuel supply tube even when the slide is in a closed position and for directing air toward and around the outlet when the slide is in an open position. The bottom of the rear panel has a cut-out portion in alignment with the metering rod and fuel outlet at the throat for the purpose of directing high speed air flow toward the metering rod and around the fuel outlet. The metering rod is provided with a downwardly and inwardly tapered, rear flat face and is mounted for longitudinal adjustment relative to the slide member. A shroud surrounds the forward face of the rod adjacent the fuel outlet to reduce turbulence, and an air supply channel surrounds the fuel outlet to promote a balanced system and an optimum fuel-air ratio.
