Abstract
The present disclosure provides a two-dimensional motor piston pump, including a two-dimensional motor and a two-dimensional piston pump. The two-dimensional motor and the two-dimensional piston pump are nested with each other and arranged coaxially. The two-dimensional motor includes a stator and an outer rotor, and the outer rotor is coaxial with the stator and is sleeved outside the stator. The two-dimensional piston pump includes: a flow distribution mechanism including a flow distribution rotor and a pump body, a piston mechanism including a left cam and a right cam; a roller assembly including a roller and a roller shaft, and a pump housing, a left end cover, and a right end cover.
