Four-way hydraulic transformer with axial flow distribution structure

The invention discloses an axial flow distribution type four-way hydraulic transformer. The transformer comprises a main shaft, a hydraulic transformer shell, a plunger, a cylinder body, a flow distribution plate, a transition plate, a flow distribution shaft shell, a flow distribution shaft, a rear end cover, a servo motor and a rotary Glyd ring. Four kidney-shaped grooves are formed in the flowdistribution plate, a through flow distribution plate flow channel is formed in the center of each kidney-shaped groove of the flow distribution plate, flow distribution shaft flow channels corresponding to the flow distribution plate flow channels are formed in the flow distribution shaft, the rear end of the flow distribution plate is connected with the flow distribution shaft in a sealed mode through a pin, the flow distribution plate is coaxial with the flow distribution shaft, and the flow channels in the flow distribution plate and the flow distribution shaft sequentially and correspondingly communicate; and fou
