【 摘 要 】

In this study a highly efficient compressed air driven hydraulic motor system is designed, developed and tested. The basic concept of using a hydraulic motor to transform the energy of compressed air (which compressing the hydraulic oil) to mechanical energy is developed, which can use the energy in compressed air more efficiently than the traditional piston type air engine. However, due to the air pressure exhale from the converter still has some energy. To recover the energy, a booster is used to recover the energy. In this study, both theoretical model and experiment device of the system are developed; several experiments to validate the theoretical model are made. It was found that the efficiency of the system is good when using the booster.
