摘要： In at least some implementations, a throttle body assembly for a combustion engine includes a throttle body having a pressure chamber in which a supply of fuel is received and a throttle bore with an inlet through which air is received, a throttle valve carried by the throttle body with a valve head movable relative to the throttle bore to control fluid flow through the throttle bore, and a metering valve carried by the throttle body. The metering valve may have a valve element that is movable between an open position wherein fuel may flow from the pressure chamber into the throttle bore and a closed position where fuel is prevented or substantially prevented from flowing into the throttle bore through the metering valve.

摘要： A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly includes an intermediate gear and a sector gear and transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the sector gear and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the pinion gear causes rotation of the gear assembly, against the bias on the sector gear, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A positon sensor assembly determines a position of the plate.

摘要： Disclosed is an adjustable apparatus for regulating the flow of fuel into a carburetor by use of a specially designed fuel metering rod. The hollow rod includes four different sets of holes along its sides at one end, each set separated from the adjacent sets by ninety degrees (90.degree.). The holes of each set are graduated from large to small, and each set covers a different range of hole sizes. The rod slides into a housing on the side of the carburetor, the holes regulating the amount of filtered fuel delivered to the carburetor. By sliding the rod, different sized holes on the rod line up with the exit opening in the housing to the carburetor. Sliding the rod also moves a linkage which causes the opening or closing of the air valves of the carburetor. The rod may be removed and rotated (either 90.degree., 180.degree. or 270.degree.) to allow a different set of holes to line up with the exit opening to the carburetor.

摘要： An improved glow-plug engine for use with a model airplane of the type that includes an output shaft for driving a propeller, a needle valve for controlling a flow of fuel into a carburetor, and a fuel line formed from resilient silicone rubber is provided, wherein the improvement comprises a pinch valve for controlling the flow of fuel through the fuel line which is located farther away from the propeller than the needle valve so that the fuel flow may be adjusted by the fingers of the engine's operator more safely. The pinch valve includes a valve body for securing a section of the resilient fuel line, and a pinching mechanism including a control member that is accurately extendible toward and retractable from a secured section of the fuel line to constrict or expand the fuel flow path defined by the secured section of the fuel line. In one embodiment, control member is a cam mounted on a lever which in turn is linked to a servo-mechanism. In another embodiment, the control member is a threaded rod that clampingly engages the section of tubing secured by the valve body. The pinch valve may be conveniently retrofitted on a conventional model airplane engine and used in combination with the needle valve, or it may supplant the needle valve.

摘要： The improved carburetor of the present invention provides for direct mechanical control of both an airflow valve and a fuel dispersion assembly such that operation of the airflow valve regulates the amount of air flowing through the carburetor. The fuel dispersion assembly and the airflow valve are mechanically connected by a three bar linkage assembly; the middle linkage being of adjustable length. Mounted within the carburetor is a throttle valve which, when opened, affects the position of the airflow valve. The fuel dispersion assembly comprises a pair of concentric tubes, one rotatable relative to the other and both having one or more radial slots therethrough. A center tube, or "slave" tube, contains fuel from a fuel storage tank. An outer tube, or "sleeve" tube remains affixedly secured to the carburetor. Upon rotation of the slave tube within the sleeve tube, a portion of the slots in each tube overlap, providing a passageway for the fuel, contained in the slave tube, to disperse within the carburetor. The slots located on the sleeve tube are oriented downwardly so that fuel is dispersed through the sleeve tube toward the bottom of the carburetor in a fan-like configuration--the arc of the fan varying with the amount of slot overlap and thus the amount of fuel dispersed.

摘要： Apparatus for adjustment of the main metering jet of a modular type high performance engine carburetor avoiding the problem of having to partially disassemble the carburetor in order to change the main metering jets. The invention includes a continuously adjustable elongated metering rod having a tapering point proximate the fuel orifice hole of an elongated cylindrical fuel metering jet, the rod adapted to pass horizontally through the carburetor float bowl module to the outside of the carburetor for external adjustment. The main metering jet is modified by a transverse located opening to pass fuel to the longitudinal fuel orifice hole with a second larger diameter concentric longitudinal hole adapted to receive and guide the metering rod pointed end into the fuel orifice hole. The metering rod passing through the wall of the float bowl module is rendered liquid-tight by means of closely threaded internal threads on an inside bushing mating with external threads on the metering rod, and an O-ring between the head of the bushing and the wall of the float bowl module with a nut screwed onto the external threads of the bushing shank exteriorly to the float bowl module. The metering rod presents a screwdriver slot for manual rotational fuel adjustment.
