Zusammenfassung:The utility model belongs to hydraulic elements in the mechanical industry, and particularly relates to a flow control slide valve structure of a hydraulic pump. The valve rod is divided into three sections of bosses, a hole channel is formed between the first section of boss of the valve rod and the second section of boss of the valve rod and communicated with an end oil through hole, a valve hole is formed between the first section of boss of the valve rod and the second section of boss of the valve rod in the pump body, and a hydraulic oil input hole is formed in the position, connected with the end oil through hole, of the pump body. The valve rod second section boss and the valve rod third section boss are matched with the valve hole to play a role in supporting and sealing at the same time. The flow control slide valve structure of the hydraulic pump enhances the stability of movement of the valve rod, and avoids the problem that the function of the oil pump is reduced due to reduction of volume efficie
