[0002] A carburetor is a mechanical device that mixes gasoline and air in a certain proportion under the vacuum generated by the operation of an engine. It atomizes gasoline by using the kinetic energy of an air flow. Its complete device should include a starting device, an idling device, a medium-load device, a full-load device, and an acceleration device. The carburetor automatically mixes the corresponding concentration and outputs the corresponding amount of mixed gas according to the different working state requirements of the engine.

[0003] During the use of the existing carburetors, the adjustment of the throttle is achieved by the up and down movement of a plunger. To meet the requirements of large-scale equipment, the volume of the carburetor will also increase accordingly. To ensure the air intake volume, the volume of the plunger will also increase. And since the plunger is cylindrical, the volume of the carburetor will further increase, resulting in a series of problems caused by the oversized carburetor, such as affecting installation, being too heavy, and too large.

[0009] When the gate body is matched with the matching channel, the two side faces of the gate body facing the air flow channel are working faces, the working faces are horizontal planes, and the edges of the working faces are rounded.

[0010] Preferably, the two working faces are provided with coatings, and the colors of the coatings are different.

[0011] Preferably, the two working faces are respectively provided with different identification coatings.

[0012] Preferably, a second weight-reducing groove is arranged on the top of the gate body, and the four connecting holes are arranged in the second weight-reducing groove.

[0030] As can be seen from the above description, by arranging the cuboid gate body 2, the problem of large space occupation caused by the traditional plunger being a cylinder can be avoided, and it can be used on a large carburetor to reduce the volume and weight of the carburetor; and through the rounded edges, it can help reduce the generation of eddy currents when the air flow passes, reduce energy loss, and improve the overall working efficiency of the carburetor; through the four connecting holes 22 arranged at the four corners, the connection relationship or the tightness relationship between the throttle cable and the four connecting holes 22 can be adjusted according to the friction situation, ensuring balance and avoiding the problem of excessive wear on one side, and the gate-type plunger structure is simple, convenient for maintenance, and also convenient for production and maintenance.

[0031] Furthermore, the two working surfaces 23 have coatings, and the colors of the coatings are different.

[0032] As can be seen from the above description, through the working surfaces 23 with coatings of different colors, during use, the wear situation can be judged by observing the degree of color fading, and at the same time, the front and back can be distinguished during installation, improving the efficiency.

[0033] Furthermore, the two working surfaces 23 respectively have different marking coatings.

[0034] As can be seen from the above description, through the marking coatings, it is easier to distinguish the front and back, improving the installation efficiency.

[0036] Further, a weight reduction hole 25 is provided at the bottom of the second weight reduction groove 24.

[0037] As can be seen from the above description, through the first weight reduction groove 21, the second weight reduction groove 24, and the weight reduction hole 25, the weight of the gate body 2 can be reduced, which helps to improve the response ability of the carburetor to rapid changes in the throttle valve, and is beneficial to the acceleration performance and transient response characteristics of the engine.

[0038] Further, the weight reduction hole 25 has the same distance from the four connecting holes 22.

[0039] As can be seen from the above description, by making the distances of the four connecting holes 22 the same, the balance of the position of the weight reduction hole 25 can be ensured.

[0040] Further, an arc-shaped slot 26 is provided at the bottom of the gate body 2.

[0041] As can be seen from the above description, through the arc-shaped slot, the air flow channel 11 will not be blocked when the gate body 2 is opened.

[0042] Further, the material of the gate body 2 is aluminum alloy.

[0043] As can be seen from the above description, by setting the aluminum alloy, the weight of the gate body 2 can be made lighter, which is beneficial to the transient response.

[0044] Further, a counterweight groove 27 is provided in the first weight reduction groove 21, and a counterweight block 28 is threadedly connected in the counterweight groove 27.

[0045] As can be seen from the above description, by setting the counterweight block 28, the stability of the operation of the gate body 2 can be further ensured.

[0046] Further, the edge of the fitting channel 12 is rounded.

[0047] As can be seen from the above description, through the rounded fitting channel 12, the problem that the gate body 2 is scratched by the sharp body of the carburetor and causes poor sealing can be avoided.
