The lack of direct conversion of hydraulic energy into pneumatic energy is considered to be one of the current problems in the sphere of energy conversion technologies. The purpose of this study is to determine the efficiency of the process of converting the initial hydraulic energy into useful pneumatic power at a laboratory experimental installation. As a result of the study, there has been determined the efficiency of direct energy conversion. This technology eliminates four extra stages of conversion. The efficiency of this conversion of hydraulic energy into pneumatic power is approximately 30% higher as compared to traditional technology. The results obtained contribute to the development of the technology of direct conversion of hydraulic to pneumatic energy.
