[0008] Furthermore, the nozzle body includes a nozzle portion and a connecting portion, an outer wall of the nozzle portion is provided with a boss, and the boss is arranged adjacent to the oil injection port of the nozzle portion.

[0009] Furthermore, a sealing platform is provided at one end of the nozzle portion away from the oil injection port.

[0010] Furthermore, an inclined sealing surface is provided at one end of the sealing platform away from the spraying piece.

[0011] Furthermore, at least one spring is provided in the adapting groove, and two ends of the spring are respectively in contact with the fixing nut and the filter.

[0012] Furthermore, an oil hole is provided on the outer wall of the fixing nut, and the oil hole is arranged adjacent to the push rod.

[0013] Furthermore, both ends of the spring are flat.

[0014] The beneficial effects of this utility model include: a filter design that improves fuel combustion efficiency. The single spring reduces the internal resistance of the fuel nozzle while maintaining the original technical performance, thereby increasing fuel output per unit time. A multi-layer filter effectively filters impurities from the fuel. The nozzle body design achieves a sealed connection without the need for an additional sealing ring. An improved retaining nut ensures more uniform force distribution, while the flat design of the spring provides more stable support. BRIEF DESCRIPTION OF THE DRAWINGS
