するパイロツト油圧回路を設けたことを特徴とす
る油圧モータの停止位置補正用油圧回路。 In a hydraulic circuit that stops the operation of the hydraulic motor by closing the hydraulic oil supply/discharge passages to the hydraulic motor, a pilot type bypass valve is inserted between the hydraulic oil supply/discharge passages. At the same time, the bypass valve is kept closed while the hydraulic motor is in operation, and immediately after the hydraulic motor stops operating, a means for mechanically correcting the rotation stop position of the output shaft is operated and the bypass valve is opened. A hydraulic circuit for correcting a stop position of a hydraulic motor, characterized in that it is provided with a pilot hydraulic circuit that brings the valve into a valve state.
