Description

Technical Field

[0001] The utility model belongs to the technical field of fuel injectors, and in particular relates to a fuel injector support plate. Background Art

[0002] The high-pressure common rail injector is the most core component in the common rail system. The internal structure and working principle of the injector have a great influence on the responsiveness, reliability and durability of the injector. The support is one of the important accessories on the high-pressure common rail injector.

[0003] A search of the document with publication number (CN216554183U) discloses a support for a high-pressure common rail injector. The support body includes a protective mechanism mounted on the exterior of the support body, multiple equally spaced slots, and a mounting mechanism mounted on the bottom of the support body. The protective mechanism shields the exterior of the support body, thereby providing protection.

[0004] The above device can shield the outside of the support body through the protective mechanism, thereby protecting it and reducing the probability of damage to itself. In addition, the protective mechanism is easy to disassemble and assemble, and is easy to use in practice.

[0005] The above device fixes the injector through the cooperation between the screw and the screw hole, but after long-term use, a large amount of oil mixture adheres to the surface of the screw due to the oil sprayed by the injector. When the worker needs to remove the injector, the disassembly tool will slip on the screw with the oil adhered, making disassembly difficult. The injector on the support body cannot be removed, resulting in the support body being scrapped and the support body needing to be replaced, increasing maintenance costs.

[0006] In view of this, the present utility model is proposed. Utility Model Content
