Through the mechanical, electrical, hydraulic ponents, the assembly constituted by the work group with stroke and rushed revision control system to adjust and control the aircraft reciprocating body traction pump oil wells set by the stroke and the rushing back and forth consecutive working . Motor power output shaft and the pump rotor shaft directly or through a coupling ponent to achieve with the connection, via the hydraulic control valve, the working fluid filters, piping, accessories will be the working fluid between the tank and pump together into groups and workloop hydraulic control, hydraulic ponents that make up the hydraulic power source part. One kind of sliderstyle disk drive low speed high torque hydraulic motor drive plate assembly wheel peripheral surface with a direct and flexible rope or belt or chain drive transmission parts corresponding with the structure of the drive wheel, which constitute the ponents of the power conversion and transmission parts. It features: simple structure, manufacture, use, maintenance costs low, clear energy.
