[0021] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:
[0022] Combine Figure 1-5 , The main structure of a two-way fuel-injection electronically controlled fuel injector with grooves of the present invention includes a fuel injector head 1, a fuel injector body 14, a restrictor valve assembly 3, a solenoid valve assembly 13, and a tight cap 5. Needle valve limiting sleeve 11, needle valve seat 7, needle valve body 8, and nozzle 9. The injector head 1 and the injector body 14 are matched and connected by threads, and are sealed by a sealing ring 15 placed on the injector body 14. The main oil inlet 16 on the injector head 1 communicates with the pressure accumulating cavity 2 in the injector body 14. Below the injector body 14 are the solenoid valve assembly 13, the needle valve seat 7 and the needle valve body 8, which are assembled and connected by a tight cap 5. The restrictor valve assembly ...
