Problems solved by technology

[0006] Through the above scheme, we can use the cooperation between the plastic sleeve and the carburetor body to overcome the problem of insufficient precision caused by the cooperation between the original metal thread and the metal thread, and it is very convenient to solve the problem of fuel leaking from the valve chamber to the outside, or air The problem of entering the valve chamber from the outside, moreover, the regulating valve with anti-loosening device can resist vibration so as to be firmly supported on the body

Abstract

The invention relates to a carburetor of a gasoline engine, in particular to a carburetor of the gasoline engine which is provided with an anti-loosening sleeve on a fuel needle. The technical proposal of the invention is as follows: the carburetor of the gasoline engine which is provided with the anti-loosening sleeve on the fuel needle is characterized in that an adjusting rod is fixedly sleeved with a plastic sleeve which is arranged between a thread spindle part and an adjusting cap. By adopting the technical proposal, the novel carburetor of the gasoline engine which is provided with the anti-loosening sleeve on the fuel needle overcomes the shortcomings of the prior art, has the high-accuracy match between the fuel needle and a carburetor body, and does not leak fuel.

Description

technical field [0001] The invention relates to a gasoline engine carburetor, in particular to a gasoline engine carburetor with an anti-loosening sleeve arranged on the oil needle. Background technique [0002] The existing gasoline engine carburetor basically includes a carburetor body, a main fuel supply device, an idle fuel supply device, a starting device, a throttle valve, and an oil supply pipe interface. According to the technical state, adjust the oil needle that controls the fuel supply of the main fuel supply device and the idle speed fuel supply device, so that when the carburetor supplies fuel to the engine, the ratio of fuel to air can be optimally mixed. However, the adjustment oil needle of the existing structure and the carburetor body are usually directly threaded, so that the precision of the cooperation between the two is not high, and it is easy to cause oil leakage, which affects the normal adjustment and sensitivity of the carburetor, resulting in the ...
