Abstract
In recent years, the power conversion using oil pressure attracts attention as measures against global environment problems. Although a hydraulic system motor is effective in oil pressure-power conversion, these are designed for high pressures such as several 10 MPa. So apparatus suitable for the oil pressure-power conversion of low-pressure is needed from now on. Authors made the property evaluation equipment for the power recovery which built into the closed circuit used the multi-vane type liquid circulation pump, and performed evaluation examination about the power recovery from the circulating oil of sveral MPa.
