Two-dimensional motor combined piston pump

According to the two-dimensional motor combined piston pump, two two-dimensional motor piston pumps are integrated to achieve parallel output, the two-dimensional motor combined piston pump comprises a two-dimensional motor and a two-dimensional piston pump, an outer rotor of the two-dimensional motor serves as a piston and a flow distribution mechanism of the two-dimensional piston pump at the same time, and the two-dimensional motor combined piston pump rotates and axially moves in the working process. Two single pumps are integrated together to realize parallel output, so that the piston pump has a larger power-to-weight ratio; partial structures of the two-dimensional motor and the two-dimensional piston pump are shared, so that the structure is more compact; the rotor of the two-dimensional motor does not need to be supported by a bearing, so that the problem that the service life of the motor is influenced by axial force is avoided; the rotation and axial movement of the rotor are converted into magneti
