Zusammenfassung:	PURPOSE: To vary allowable pressure in a motor pipe in accordance with a working direction by providing a branch pipe furnished with one restriction and an overpressure valve on each of introduction parts and connecting the introduction parts to a remaining part of a load pressure pipe through a selector valve. CONSTITUTION: Two introduction parts 21, 22 are provided on a load pressure pipe 9. The introduction part 21 is connected to a load pressure sensing part 24 and the introduction part 22 is connected to a load pressure sensing part 23. The introduction part 21 is connected to an overpressure valve 29 through a branch pipe, and the introduction part 22 is connected to an overpressure valve 30 through the branch pipe, and restrictions 27, 28 are respectively provided on the introduction parts 21, 22. Consequently, as it is possible to adjust the overpressure valves 29, 30 respectively to different working values, it is possible to change working pressure in accordance with a working direction of a hydraulic motor 3.
