As the pressure rises, the high-pressure oil acts on the upper end of the guide plug through the nozzle, pushing the guide rod and the control valve core. Because this thrust is greater than the force of the adjusting spring, the control valve core moves downward to make high-pressure oil flow into the lower chamber of the variable piston through a transverse hole. At this time, the oil pressure at the upper and lower ends of the variable piston is equal, but the lower end area is larger and the upper end area is smaller. Therefore, Manufacturer of cycloidal hydraulic motor Under the effect of the pressure difference at both ends, the variable piston moves upward, thus reducing the swing angle and achieving the purpose of variable. At the same time, the change of torque and displacement will also cause the corresponding change of high-pressure oil pressure. At this time, the spring force of the adjusting spring at the lower end of the control valve core is greater than the pressure exerted on it by the upper guide rod, OM series cycloidal hydraulic motor The control valve core will move upward until the control oil circuit on the valve sleeve is cut off, so that the variable piston is fixed A location.
