Abstract
A two-dimensional motor combination piston pump by combining two independent two-dimensional piston pumps into one structure is provided. The combination piston pump includes a two-dimensional motor and a two-dimensional piston pump. The outer rotator serves as the piston and the flow distribution mechanism of the two-dimensional piston pump. While operating, outer rotator rotates and moves axially.
