Description

Technical Field

[0001] The utility model relates to the field of fuel injection nozzles, in particular to a fuel injector assembly.

[0002] Background Technology

[0003] The injector is a precision device with very high processing accuracy. It is required to have a large dynamic flow range, strong anti-clogging and anti-pollution capabilities, and good atomization performance. The injector receives the injection pulse signal sent by the ECU and accurately controls the fuel injection amount. The spray characteristics of the injector include atomization particle size, oil mist distribution, oil beam direction, range and diffusion cone angle, etc. These characteristics should meet the requirements of the diesel engine combustion system to achieve perfect mixture formation and combustion, and obtain higher power and thermal efficiency.

[0004] The existing fuel injectors have no protection function for the nozzles, so that when the fuel injectors are placed, it is easy for a lot of dust to enter the nozzles, affecting the use of the fuel injectors. At the same time, due to the lack of corresponding filtering components, impurities in the oil during the injection process block the injection, affecting the use of the entire fuel injector. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the fuel injector lacks a corresponding filter component, resulting in impurities in the oil blocking the fuel injection during the fuel injection process, thus affecting the use of the entire fuel injection nozzle.

[0007] A limiting groove is provided inside the filter plate, a spring is fixedly connected inside the limiting groove, the other end of the spring is fixedly connected to the limiting plate, and a maintenance plate is arranged outside the buffer chamber.

[0008] Preferably, a positioning block is fixedly connected to the other end of the limit plate, and a positioning groove is provided on the mounting plate. The positioning block corresponds to the positioning groove. When the filter plate needs to be disassembled and cleaned, the positioning block is pressed upwards, and the positioning block can be retracted inward under the action of the spring. At this time, the staff can pull the entire filter plate outward to take it out for cleaning, thereby improving the filtering effect of the entire filter assembly.

[0009] Preferably, a heat insulating pad is provided on the inner wall of the outer tube, and a solenoid valve is provided inside the outer tube. The heat insulating pad can insulate the oil inside the device, thereby increasing the service life of the fuel injector.

[0010] Preferably, a nozzle is provided through the bottom of the outer tube, and connecting blocks are fixedly connected to both ends of the outer side of the outer tube.

[0011] Preferably, a cylinder is provided at the lower end of the connecting block, and the extending end of the cylinder is fixedly connected to the connecting block, and the bottom of the cylinder is fixedly connected to a base, and the entire fuel injector can be moved up and down by utilizing the extension and retraction of the telescopic rod, and the sealing plate is covered on the nozzle to protect the nozzle.

[0012] Preferably, a through hole is opened inside the base, and positioning pieces are fixedly connected to both ends of the lower side of the base.

[0013] Preferably, a sealing plate is correspondingly arranged inside the positioning member, and screw holes are arranged on the positioning member and the sealing plate 3, and the two are locked by bolts, so as to improve the stability and sealing performance during use.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. The utility model can connect the device to the external oil pipeline through a threaded connector, and can filter the oil during oil transportation by using a buffer chamber and a filter plate to prevent impurities from clogging the nozzle. The heat insulation pad can insulate the oil inside the device, which is convenient for the use of the device at high temperatures and enhances the applicability of the device. Compared with the prior art, the oil can be filtered during oil injection to improve the quality of oil injection.

[0016] 2. The utility model can drive the entire fuel injection nozzle to move by arranging a cylinder, so that the nozzle can contact the sealing plate. The sealing plate can protect the nozzle and prevent external dust from entering the nozzle and causing its influence. BRIEF DESCRIPTION OF THE DRAWINGS
