The invention discloses an electro-hydraulic power steering pump assembly. The electro-hydraulic power steering pump assembly comprises a supporting seat and an oil pot. The supporting seat comprises a mounting base and a sleeve connected with the mounting base and further comprises an oil storage structure communicated with the oil pot. The oil storage structure comprises an oil inlet groove, a curved oil storage groove, an oil storage cavity and a cover plate used for closing the oil storage groove, the oil inlet groove, the oil storage cavity and the oil storage cavity are formed in the end face of the mounting base, one end of the oil storage groove is communicated with the oil inlet groove while the other end of the oil storage groove is communicated with a bearing placement cavity, and the oil storage cavity is communicated with the oil storage groove. The electro-hydraulic power steering pump assembly has the advantages that since the oil storage structure is arranged on the supporting seat and the oil storage groove is curved, oil flows in through the oil inlet groove and then flows to the bearing placement cavity along the curved oil storage groove, on the one hand, oil storage capacity is improved, and on the other hand, in-flow oil can slow down, so that stability of a whole oil circuit can be improved.
