More Information
Summary:The invention discloses an air control device of a cam structure, and relates to the field of aero-engine air control systems. The air control device of the cam structure comprises a valve body, a rail shell is arranged above the valve body, a cam is arranged on the inner wall of the rail shell, and the end of the cam is connected with an actuating cylinder body. According to the air control device of the cam structure, the piston rod of the actuator cylinder moves to drive the cam mechanism, full opening and full closing of the valve are achieved, passing and cut-off of cooling air are achieved through full opening and full closing of the valve, under the action of the high-temperature sealing assembly and the metal sealing ring, the high-temperature sealing performance of the air valve is high, the engine efficiency is improved, and the service life of the engine is prolonged. Under the action of the loading force of the actuating cylinder, a cam mechanism is adopted for force transmission, and valve clampi
