Abstract
PURPOSE: To make a hydraulic motor highly responsive to the variation in revolutions thereof in raising the torque thereof by providing a throttle valve with a check valve for throttling on return duct side between a flexible pipe and a hydraulic pump.
CONSTITUTION: A flexible piping 9 is provided between a change-over valve 4 and a hydraulic motor 8 to supply pressure oil from a hydraulic pump 2 to a hydraulic motor 8 while change-over is made by said change-over valve 4. Further, a throttle valve 10 with a check valve for throttling on return duct side is provided between said flexible piping 9 and a hydraulic pump 2, and a reducing valve 12 between said change-over valve 4 and a tank 3. The response time to the increase of the load of said hydraulic motor 8 is reduced. This is utilized to raise the torque of said hydraulic motor 8 so that the seizure between a hob and works is prevented.
