Abstract: The present disclosure provides a two-dimensional motor combination piston pump by combining two independent two-dimensional piston pumps into one structure to achieve parallel outputting. 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. By combining two independent two-dimensional piston pumps into one structure to achieve parallel outputting, the combined piston pump has a greater work-to-weight ratio. The two-dimensional motor and the two-dimensional piston pump may share some structures in common, allowing the structure of the combination piston pump to be compact.

Abstract: An electro-hydraulic servo valve, which has an adjustable null position and can be directly driven by the motor, is provided and includes four parts: a slide valve assembly, a two-dimensional motor, a magnet resetting-to-null mechanism, and a displacement sensor, and the four parts are set coaxially arranged. The slide valve assembly is a conventional two-dimensional servo valve structure. The two-dimensional motor may directly drive the valve core to rotate to further control a size of an opening opened by a valve. The magnet resetting-to-null mechanism is configured to reset the valve to the null position. The displacement sensor may monitor a position of the valve core in real-time and feedback signals to achieve closed-loop controlling.
