Novel fuel gas cavity for oil-gas dual-purpose carburetor

Abstract

The invention discloses a novel fuel gas cavity for an oil-gas dual-purpose carburetor, and relates to the technical field of carburetors. The novel fuel gas cavity for the oil-gas dual-purpose carburetor comprises a lower cover and a fuel gas cavity shell; the lower end of the lower cover is fixedly connected with an upper connecting pipe, the lower end of the upper connecting pipe is fixedly connected with a connecting rubber pipe, and the lower end of the connecting rubber pipe is connected with a lower connecting pipe; and a fuel gas cavity is arranged in the fuel gas cavity shell, the portion, located at one end of the lower connecting pipe, of the interior of the fuel gas cavity shell is connected with an oil discharge cavity in a cut-through mode, and the lower end of the oil discharge cavity is connected with an oil way pipe in a cut-through mode. According to the novel fuel gas cavity for the oil-gas dual-purpose carburetor, through cooperative design of the upper connecting pipe, the lower connecting pipe and the connecting rubber pipe, the relative distance between the two connecting pipes is shortened, the using length of the connecting rubber pipe is decreased, and meanwhile material consumption of parts is reduced; and the internal oil way design is adopted, and therefore the problem that in the traditional external oil way design, the reliability of an oil way can not be guaranteed due to the fact that the connecting rubber pipe is exposed to a high-temperature operation environment for a long term is solved.

Description

technical field [0001] The invention relates to the technical field of carburetors, in particular to a novel gas chamber used in an oil-gas dual-purpose carburetor. 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 uses the kinetic energy of the inhaled air flow to realize the atomization of gasoline. Its important effect on the engine can be called the "heart" of the engine, and the present invention is exactly a kind of carburetor with both oil and gas. [0003] At present, the gas chambers used in the oil-gas dual-purpose carburetors on the market all use external oil passages, and the oil passages are connected through the connecting rubber pipes on the oil pipes, and the relative distance between the two connecting pipes is relatively far, resulting in the connection of the rubber pipes. The length is longer. S...

AI Technical Summary

Problems solved by technology

[0004] From the above content, it can be seen that the traditional gas chamber has more requirements on the amount of oil discharge parts, stricter requirements on oil resistance, heat resistance and wear resistance of materials, and there are certain hidden dangers in quality and safety. Therefore, those skilled in the art provide a kind of A new type of gas cavity on an oil-gas dual-purpose carburetor to solve the problems raised in the above-mentioned background technology
