This utility model provides an oil pump body for a diesel internal combustion engine, relating to the technical field of oil pump bodies. It includes a pump body and an armature. The armature is centrally located within the pump body, and a magnet is fitted around the outer side of the armature's middle portion. A front fixed plate is located at the front end of the pump body, and a one-way valve is located in the middle of the front part of the front fixed plate. A front connecting sleeve is fixed to the front part of the inner sidewall of the pump body, and a first sliding groove is provided on the front part of the inner side of the front connecting sleeve, while a second sliding groove is provided on the rear part of the inner sidewall of the front connecting sleeve. A middle slider and a front slider are provided on the front part of the outer ring of the armature. The middle slider is rotatably connected to the first sliding groove, and the front slider is rotatably connected to the second sliding groove. This utility model ensures that both the front and rear parts of the internal armature are rotatably connected to the front and rear connecting sleeves, respectively, achieving front-to-back balance during high-speed rotation. This results in smoother and more stable operation of the internal structure, strengthens the pump body casing, and provides safety, explosion-proof protection, and robust reliability.
