摘要： A variable fuel admission carburetor is provided comprising a piston and cylinder that are mated concentrically, and coexist in a carburetor chamber. The cylinder comprises a longitudinal slot which allows varying amount of fuel into the carburetor. Through the relative longitudinal movement of the piston in the cylinder, the exposed length of the slot is varied, thereby varying the amount and rate that the fuel enters the chamber.

摘要： A fuel regulating method and mechanism for a rotary throttle (barrel-type) carburetor which prevents an end-user A/F adjustment that would cause increase in fuel quantity to a level in excess of a regulated value so as to comply with the exhaust gas emissions regulations. A cylindrical throttle valve having a throttle hole is disposed in an air intake passage of the carburetor body 12, the air flow is controlled by rotation of the throttle valve and the fuel flow is controlled by the position of a fuel regulating needle, attached to the throttle valve, relative to a fuel jet port of a fuel supply pipe in the carburetor body due to axial movement of the throttle valve. A bypass passage is provided within the carburetor body to communicate the throttle valve hole and fuel jet area with the air intake passage upstream of the throttle valve. An air flow regulating needle valve in the air passage is operable to adjust the bypass air flow in the air passage to lean the pre-set idle A/F ratio from a maximum rich factory adjustment. The fuel regulating needle valve is sealed to prevent exterior access by the end-user after making the factory adjustment.

摘要： A dual fuel carburetor includes a carburetor body, a main jet pipe and a float chamber housing to form a float chamber, the needle valve device includes a pushing needle and a needle valve base, the pushing needle is movably inserted in the float chamber housing, and a window is formed at a bottom of the float chamber housing, the needle valve device further includes a sealed corrugated sleeve positioned around the pushing needle, which has a first end hermetically connected with the pushing needle and a second end hermetically connected with the float chamber housing, a driving spring is positioned around the pushing needle, and the pushing needle has a driving end extended out from the float chamber housing and opposite to that end cooperated with the valve base hole. The needle valve device is in a reasonable design to obtain mechanical controls or other automated drive controls.

摘要： A carburettor including a primary air passage, an adjustable throttle valve situated within the primary air passage, a fuel supply nozzle communicating with the primary air passage and connected to a fuel metering valve for varying the amount of fuel discharged through the nozzle and a rotary input shaft adapted to be connected to an engine speed control member and which is connected to the throttle valve to move the throttle valve between open and closed positions. The rotary input shaft is also connected to a carriage to move the carriage, the carriage carrying at least one elongate inclined ramp which extends in the direction of movement of the carriage and which is engaged by a follower connected to the valve member. Rotation of the input shaft results in movement of the throttle valve and in movement of the carriage and thus of the elongate ramp, wherein the follower is moved transverse to the length of the ramp and the valve member of the fuel metering valve is thus also moved.
