Hydraulic transformer is an innovational hydraulic component, by which energy can be gotten from common pressure rail without throttling loss and the pressure and flow of hydraulic system can be controlled. The structure characters and working principles of 3 types of hydraulic transformer, including traditional type and new type, were introduced, and the developments of the 3 types of hydraulic transformer and their energysaving applications in hydraulic system were discussed. Some problems existed in theory analysis and practical application of the new type hydraulic transformer were also given, and the application of hydraulic transformer in the future was prospected.
