PURPOSE:To easily vary the torque of a hydraulic motor by connecting a reduction gear using gears to the hydraulic motor and operating said reduction gear as motor or pump. CONSTITUTION:A reduction gear (r) using gears is connected in parallel to a hydraulic motor (m), and is provided with the reduction gear function and the fluidic mechanical function. Therefore, when fluid passages 30 and 31 are connected to the reduction gear (r) by selector valves 25 and 27, the reduction gear (r) operates as gear pump or gear motor, and the substantial torque of the hydraulic motor (m) connected in parallel can be easily varied. |
