    摘要： A cap (40) and method for limiting the range of adjustment of a fuel flow metering valve (36) in a carburetor. The cap (40) has a body (82) with an arm (84) projecting generally radially outwardly therefrom to abut against a stop carried by the carburetor to limit valve rotation and a passage (86) therein for telescopically axially receiving the head end (62) of a shank (60) of the valve (36). Portions within the passage (86) enable the cap (40) to be retained in the shank (60) of the valve (36) in a freely rotating first position during assembly and arm orientation, and in a second position securing the cap (40) to the valve (36) to limit adjustment and maintain emissions calibration. Preferably, the cap (40) may also be moved to a third position to releasably drivingly engage the valve (36) to perform fuel flow adjustment before securing the cap (40) to the valve (36). The cap (40) can also be prepositioned angularly relative to an adjusted position of the valve (36) before it is moved to its second position on the valve (36) to limit the extent of subsequent adjustment of the valve (36).

    摘要： A fuel metering system for a combustion engine carburetor utilizes a non-convoluted, planar, flexible diaphragm which does not require a molding process to form a traditional convolution. The diaphragm defines in part a pressure controlled fuel metering chamber on one side and a reference chamber at atmospheric pressure on the other side. During operation of the engine, sub-atmospheric pressure within a fuel and air mixing passage draws fuel from the metering chamber to mix with air for combustion within the engine. As pressure within the metering chamber thus decreases, the diaphragm flexes into metering chamber. The displacement of the diaphragm actuates a flow control valve of the metering system which flows pressurized make-up fuel into the metering chamber until the diaphragm returns to its datum position. Preferably, hardware of the flow control valve which is in direct contact with a surface of the diaphragm exposed to the metering chamber does not penetrate the diaphragm as the traditional rivet and washer assembly would. Therefore, manufacturing costs are reduced and any opportunity of leakage between the fuel metering chamber and reference chamber is eliminated. Preferably, the carburetor is of a manual external purge type in order to exert sufficient vacuum within the metering chamber to displace the metering diaphragm thus opening the flow control valve to purge the carburetor of unwanted fuel vapor and air prior to starting the engine. The novel planar diaphragm thereby resolves problems associated with traditional metering diaphragms such as variation in convolution datum height affecting flow control valve lever/diaphragm clearances, non-symmetric convolution axis or distorted convolution affecting diaphragm pressure response and recovery.
