Problems solved by technology

There is friction between the steel wire 15 and the wire skin 14. When the damper 12 is in the closed state, the friction between the two is greater than the force of the return spring 16 to ensure wind resistance. The carburetor damper structure exists as follows Defects: many parts, relatively high cost, and it is not easy to disassemble and install the carburetor
The disadvantage of the existing structure is that it is necessary to reach out to the installation position of the carburetor for operation before and after starting, which is inconvenient and dangerous to operate
[0003] A common disadvantage of these two existing structures is that after the engine is started, the damper can only be returned manually
In actual use, it often happens that the damper is still closed or semi-closed (that is, not fully returned) during driving, resulting in insufficient power, increased fuel consumption, and high emissions.

Embodiment 1

[0030] Such as image 3 , Figure 4 As shown, when the carburetor damper automatic return device of this embodiment is not activated, the throttle mechanism 3 and the damper control panel 4 adopt the installation method of a throttle type carburetor; a sliding sleeve 51 with a square through hole and The carburetor body 5 is cast into one body; a cylindrical sliding bar 6 is passed through the through hole, and is slidably matched with the sliding sleeve 51; one end of the sliding bar 6 is rotated by the second tension spring 62 and the throttle mechanism 3 The disk 33 is connected, and this end is also connected with the sliding sleeve 51 by hanging on the first extension spring 61 whose elastic coefficient of the raised part is smaller than the second extension spring 62; The first torsion spring 32 that rotates and resets; the damper control plate 4 is attached to the carburetor body through the shaft 43 that is fixed on its surface and penetrates into the interior of the ...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that the second tension spring 62 is replaced by a connecting plate, and a shift lever is designed correspondingly on the rotary disk of the throttle mechanism; shape.

[0040] Such as Figure 12 As shown, one end of the connecting plate 7 has a through hole 71, and the other end has a long hole 72.

[0041] Such as Figure 13 , as shown in 14, the through hole 71 of the connecting plate 7 is connected with the through hole 63 of the slide bar 6 through a rivet 73; the connecting plate 7 can rotate around the rivet 73; A driving rod 34 , one end of the driving rod 34 is fixedly connected to the rotary disk 33 . During production, the protruding part of the rotating disc 33 can be bent vertically downward to form the driving lever 34 .

[0042] Such as Figure 15 As shown, when refueling, when the rotary disk 33 rotates to the critical angle α according to the J direction shown in the figure, that is, the di...

Embodiment 3

[0047] The difference between this embodiment and embodiment 1 is that the telescopic pull rod is used instead image 3 The second tension spring 62 in.

[0048] Such as Figure 17 and Figure 18 As shown, the telescopic pull rod 8 includes; a tubular outer pull rod 81, the two sides of one end of the outer pull rod 81 are provided with sliding grooves 812; through the sliding groove 812, and can slide in the sliding groove 812, so that the inner tie rod 82 can move in the outer tie rod 81; the inner tie rod 82 has a through hole 821 at the outer end of the outer tie rod 81; the outer tie rod 81 has a through hole 811, the The through holes and the through holes 821 are respectively located at two ends of the telescopic pull rod 8 .

[0049] Such as Figure 19 As shown, the cotter pin 831 passes through the through hole 811 of the outer tie rod 81 and the through hole 63 of the slide bar 6 in turn; the cotter pin 832 passes through the through hole on the rotating disk 33 ...

Abstract

The present invention relates to a carburetor choke automatic return device. Said invention includes the following several portions: carburetor choke self-body, sliding sleeve with through hole, sliding bar, accelerator mechanism with rotary disk, tension spring and choke control board. Said invention also provides the connection mode of all the above-mentioned portions and the working principle of said automatic return device of carburetor choke.

Description

technical field [0001] The invention relates to an automatic return device for a carburetor damper, in particular to an automatic return device for a carburetor damper which is used on a motorcycle carburetor and can automatically lock and return the damper. Background technique [0002] The carburetor damper should be closed when starting to facilitate starting (cold start), and open (ie return) when the engine is running normally. A kind of structure of existing carburetor damper such as figure 1 shown. The steel wire stay wire 15 connects the air door 12 and the manual mechanism 13 of the carburetor 11, and the manual mechanism 13 is installed in a place where hands are easy to touch (such as on the steering handle of a motorcycle), and the opening and closing of the air door 12 is realized by controlling the manual mechanism , the G1 direction shown in the figure is the manual closing direction. There is friction between the steel wire 15 and the wire skin 14. When th...
