Abstract
Energy-saving research of hydraulic system has become a central issue recently. This paper has made a comprehensive review of the hydraulic transformer (HT) which is the key component in common pressure rail (CPR) hydraulic energy-saving system. First, the invention process and basic working principle of the HT are introduced. Then, HTs are divided into three categories to discuss the current development in accordance with the different structures for realizing the control angle regulation. In addition, the problems existing in the research of HTs are summarized and a new variable displacement HT is proposed for the first time. Finally, the future development of the HT is discussed.
