Abstract

The invention relates to a carburetor lifting mechanism, in particular to a plunger lifting mechanism of a rotary valve type diaphragm carburetor. The lifting mechanism comprises a torsion spring, a sealing cap, a cam, a plunger and a main nozzle. An oil return pipe and an oil inlet pipe are arranged in a middle section of the carburetor, and an oil cup is mounted at the bottom of a lower section of the carburetor. The plunger is disposed in the inner cavity of the body; and the cam is arranged in the inner cavity of the body through the limit groove. When in rotating of the throttle cable bracket on the top of the body, the wheel on the plunger is driven to roll along the helical surface on the cam, so that a major gauge pin in a major pin sleeve is driven to make up and down movements in the plunger. The cam is disposed in the inner cavity of the body, so that dust generated in the operation of the engine does not enter the cam to affect the normal work of the plunger, the reliability of the use of the carburetor is increased, and the proper engine work is guaranteed.

Description

technical field [0001] The invention relates to a carburetor lifting mechanism, in particular to a rotary valve type diaphragm carburetor plunger lifting mechanism. Background technique [0002] The carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum generated by the engine. As a precise mechanical device, the carburetor can be called the "heart" of the engine for its important role in the engine. Its complete device should include starting device, idle speed device, medium load device, full load device and acceleration device. The carburetor will automatically mix the corresponding concentration according to the requirements of different working conditions of the engine, and output the corresponding amount of mixed gas. In order to make the mixed gas mixed evenly, the carburetor also has the effect of atomizing the fuel , for the normal operation of the machine. [0003] Existing carburetors such as Figure 1-Figure 3 s...
