A two-dimensional electro-hydraulic servo valve based on a dual-redundancy transmission mechanism, including a valve body, a valve spool inside the valve body, and a valve sleeve on an outside of the valve spool. A low-pressure chamber is disposed between the valve spool and the valve sleeve; the valve body is connected to a servomotor through a transmission mechanism; the transmission mechanism includes a spool fork and a motor toggle, and each end of the motor toggle is connected to a spherical connector; the spherical connector is rotatable with a centerline of a connection end of the motor toggle as an axis; each end of the spool fork is slidably connected to a corresponding spherical connector; a middle part of the spool fork is connected to the valve spool, and a middle part of the motor toggle is connected to a rotor of the servomotor.

Two-dimensional electro-hydraulic servo valve based on dual redundancy transmission mechanism

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.

Two-dimensional motor piston pump

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.
