−ように構成して成る可変容量形油圧モータ制御装置。A chamber 3 on the rod side of the control piston 2 that operates to vary the capacity of the variable displacement hydraulic motor 1 is connected to the drive circuit 4 of the hydraulic motor 1! At the same time, the chamber 5 on the head side of the piston 2 can be selectively connected to the tank 9 or the drive circuit 4 via an on-off valve 3 consisting of a barrel 6 (!: a spool 7 that overlaps and slides on the barrel 6). Then, when the pressure of the drive circuit 4 is applied to the barrel 6 and the spool 7 of the opening/closing valve 8, and the operating force is small, the barrel 6 and the spool 7 connect the chamber 5 to the tank 9 without moving much. However, when the pressure is large, the barrel 6 becomes thick (moves) and connects the chamber 5 to the drive circuit 4, and when the pressure increases further, the spool 7 moves following the barrel 6 and connects the chamber 5 to the tank. 9. A variable displacement hydraulic motor control device configured as shown in FIG.
