タ。[Claims for Utility Model Registration] A swash plate 11 that is biased by a biasing means 33;
A piston 8 whose stroke is regulated by the swash plate 11 is housed in a cylinder 71, and a cylinder block 7 is connected to the main shaft 5, and a high pressure side port is in sliding contact with the piston head side surface of the cylinder block 7. 16, a valve plate 14 having a low-pressure side port 18 and a control port 19 is provided to allow high-pressure liquid to flow into the cylinder 71 through the high-pressure side port 16 of the valve plate 14, while low-pressure liquid is allowed to flow into the cylinder 71 through the low-pressure side port 18 of the valve plate 14; By discharging the liquid, the cylinder block 7 and the main shaft 5 are rotated, and the oil pressure applied to the control port 19 is switched to change the angle of the swash plate 11, thereby controlling the speed of rotation of the main shaft 5. In the variable displacement hydraulic motor, a damper 3 brakes the movement of the swash plate 11.
A variable displacement hydraulic motor characterized by having a zero.
