Abstract

The invention provides a fuel oil supply system. The fuel oil supply system comprises a body, a lower cover, a main oil well and a main spray pipe. The lower cover is in tight connection with the bodythrough a lower cover connecting piece. The main oil well and the body are of a split type structure. The top of the main oil well is in tight connection with the body. The bottom of the main oil well abuts against the bottom of the lower cover to ensure the airtightness of the junction between the main oil well and the body. A needle valve seat is arranged on one side of the main oil well. A needle valve is mounted in the needle valve seat. The main spray pipe is mounted in the main oil well and is in tight connection with the body. The fuel oil supply can be made of a plastic material, is low in cost and friendly to environment and has the characteristics of high temperature resistance, high strength, high stiffness, high corrosion resistance and the like. Meanwhile, the fuel oil supplysystem is simple in structure and simple in assembly process. Low-cost manufacturing of the fuel oil supply system is realized. The requirements for manufacturing and application can be met better.

Description

technical field [0001] The invention relates to a fuel supply system, in particular to a fuel supply system with simple assembly process, low cost and better meeting the requirements of manufacture and use. Background technique [0002] see figure 1 , figure 1 It is a perspective view of a fuel supply system in the prior art. The fuel supply system in the prior art is generally made of metal materials, which are expensive and costly; moreover, metal products are not environmentally friendly. The assembly process of the existing fuel supply system is many and complicated, thereby also increasing the cost of the fuel supply system. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fuel supply system with simple assembly process, low cost and better meeting the requirements of manufacture and use, aiming at the above-mentioned defects of the prior art. [0004] In order to achieve the above object, the present i...
