description The utility model belongs to hydraulic elements in the mechanical industry, and particularly relates to a vane pump assembly with an oil return flow guide sleeve. A vane pump is installed in a vane pump cavity of an assembly pump body in a pressing mode, a hole check ring is installed in a limiting check ring groove, the vane pump and the assembly pump body are limited and fixed, a stepped cup-shaped oil return flow guide sleeve is installed on an oil suction opening above the assembly pump body in an interference pressing mode, a gap is formed between the periphery of a lower step of the oil return flow guide sleeve and the inner diameter of the oil suction opening, and the gap corresponds to an oil return opening. According to the vane pump assembly with the oil return flow guide sleeve, the assembly mode that the vane pump is inserted into the assembly pump body is adopted, assembly is easy, the oil return flow guide sleeve is installed at the oil suction opening of the assembly pump body in an interferenc
