Description

Technical Field

[0001] The utility model relates to an anti-deformation fuel injector. Background Art

[0002] The injector is an important component of the engine fuel supply system, which is used to atomize the fuel and spray it into the combustion chamber. For example, the patent publication number CN214464619U is a wear-resistant and leak-proof injector. When installing the oil inlet pipe, first pass the oil inlet pipe through the guide body, then connect the oil inlet pipe to the oil inlet interface, and finally fix the guide body by cooperating with the leak-proof seat. The through hole inside the guide body can limit the oil inlet pipe to prevent the outer surface of the oil inlet pipe from directly contacting and rubbing with the injector body, thereby extending the service life of the oil inlet pipe, making it more durable, cost-saving and convenient to use. When installing the return oil pipe, the return oil protection body can protect the return oil pipeline through the threaded connection on the outer surface of the return oil interface to prevent the return oil pipeline from being damaged, thereby extending the service life of the return oil pipeline, and the groove protects the fixing bolt to prevent the fixing bolt from contacting and rubbing with the oil inlet pipe, thereby causing damage to the oil inlet pipe.
