The invention provides a plunger distribution axial plunger hydraulic pump, which belongs to the type of a positive-displacement pump. The invention aims at solving the problems of the prior art, namely, to reduce friction pairs working in the sea and fresh water and PV values thereof, reducing material requirements of the friction pairs, improving efficiency, and reducing noise and size. Plungerholes are arranged on the reference circle of a cylinder body, and are communicated with an absorption inlet and a water outlet arranged on the cylinder body. A plunger is slip fit to the plunger holes. A crankshaft is arranged on an end cover through a bearing. A sloping plate arranged on the bellcrank of the crankshaft is flexibly connected with the plunger through a bulb connecting rod. The plunger is a stepped shaft-type slide valve. The number of the plunger holes is 4XN. An accessory pore is arranged near each plunger hole, and is communicated with the corresponding plunger hole at the waist through a fabricatio
