摘要： In at least some implementations, a locking plate may be received between the cover plate and the adjustable valve and be movable to a first position permitting access to the adjustable valve and a second position inhibiting or preventing access to the adjustable valve. In some implementations, a latch assembly may releasably retain the locking plate in its second position. The latch assembly may include a finger carried by the locking plate and releasably engageable with a stop when the locking plate is in its second position.

摘要： A carburetor includes a base, a Venturi cone assembly, a cam assembly, a horsepower adjustment assembly, and a vacuum horsepower adjustment valve. The Venturi cone assembly is mounted in the base. A supporting portion of a cone collides with a cam of the cam assembly. An oil line rotation wheel of the horsepower adjustment assembly is drawn by an oiling line to drive the fan blade. The amount of displacement of the cone of the Venturi cone assembly under vacuum suction from the engine is controlled by a cam of the cam assembly. The vacuum horsepower adjustment valve automatically supplies enough fuel to the engine. Accordingly, the present invention can make the fuel burn sufficiently, effectively improving efficiency and reducing air pollution.

摘要： Disclosed herein is a carburetor including a housing having a throat, means for supplying fuel to the throat intermediate its opposite ends, the fuel supplying means including a tube extending into the throat and including a plurality of fuel supply openings spaced along its length. A pivotable throttle member is positioned in the throat intermediate its opposite ends and is pivotable between a fluid flow restricting position and an open position. The pivotable throttle member includes a cam surface. The carburetor is also constructed such that an increased number of the openings supply fuel to the throat as the throttle member pivots from a fluid flow restricting position to an open position and the openings are closed as the throttle member pivots from an open position to a fluid flow restricting position. This is accomplished by a sleeve surrounding the tube and supported for slidable movement on the tube, and a cam follower engaging the cam surface, the cam follower carrying the sleeve whereby the sleeve is slideable on the tube in response to movement of the cam surface with respect to the cam follower.

摘要： Means are disclosed for an improved carburetor wherein fuel is atomized for carburetion purposes by being pumped through a tube having a plurality of perforations in its periphery. The tube is covered by sleeves which telescope over it; and in reaction to either depression or release of the accelerator, the sleeves will move along the tube to either uncover or cover more or less of the holes, as desired. In this way, a more completely atomized fuel mixture is delivered to the carburetor under high pressure for improved efficiency. Tension means are also provided to return the sleeves to their normal or "idle" position following release of the accelerator.
