Improved carburetor

Abstract

The invention discloses an improved carburetor. The improved carburetor comprises a carburetor body, a bottom cover is arranged on the lower side of the carburetor body, the carburetor body is provided with an atmosphere balance hole channel communicated with external atmosphere, an atmosphere balance hole of the atmosphere balance hole channel is formed beside the portion, on the connection end face of the carburetor body and an engine, of the carburetor body, the atmosphere balance hole is connected with a pipe connector, and a drainage pipe is connected with the pipe connector. According to the improved carburetor, the atmosphere balance hole is formed beside the portion, on the connection end face of the carburetor body and the engine, of the carburetor body, overflown or leaked oil is guided and drained through the drainage pipe, and the situation that the oil is directly discharged to the high-temperature outer shell of the engine and accordingly safety accidents are caused is avoided. Additionally, the carburetor with a detachable and washable oil inlet system has the advantages that the design is reasonable, the structure is simple, the oil inlet system is convenient to disassemble and assemble and washing can be easily carried out and the carburetor has great use value and market value.

Description

technical field [0001] The invention relates to a carburetor, in particular to an improved carburetor. Background technique [0002] A 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 function of atomizing the fuel. effect for the normal operation of the machine. [0003] At present, the atmospheric balance hole of most carburetors is opened on the end face of the carburetor ...

AI Technical Summary

Problems solved by technology

Since the reverse torsion spring is installed in the shaft hole of the throttle shaft, it is necessary to cut out the groove for installation in the throttle shaft installation hole, which increases the processing procedure, and the installation is relatively time-consuming; the later maintenance is inconvenient

[0006] At present, the oil inlet pipe of most carburetors is installed in the oil inlet passage by means of interference fit, and its disassembly is extremely inconvenient

And some impurities will also be mixed in the gasoline, because there is no filter device in the oil inlet channel, it is easy to block; and because the oil inlet pipe is not easy to disassemble, it is difficult to clean, which often leads to the scrapping of the entire carburetor
