MOOG servo valve is composed of permanent magnet torque motor, nozzle, stop plate, valve core, valve sleeve and control chamber. When the input coil passes through the current servo valve, the baffle moves to the right, so that the throttling effect of the right nozzle is strengthened, the meteor is reduced, and the right side back pressure is increased; At the same time, the throttling effect of the left nozzle is reduced, the flow rate is increased, and the back pressure on the left side is decreased. The forces at both ends of the spool are out of balance and the spool moves to the left. First pressure oil flows from S to C2 to lean load. The load return oil flows through the C1 return port and into the fuel tank. The displacement of the spool is proportional to the input current of the torque motor, and the liquid pressure acting on the spool is balanced with the spring force, so the differential current of the torque motor is proportional to the displacement of the spool in the equilibrium state. If the input current is reversed, the flow is also reversed, and the table is the classification of servo valves..
