Air Bypass Valve · 模型 65146
3D Model of the Air Bypass Valve from The Saphir 20 Auxiliary Power Unit (APU). The automatic discharge valve ensures stable operation of the engine compressor in start-up and idle modes by venting some of the air from the compressor to the atmosphere. In the absence of air extraction for powering the aircraft or helicopter systems, the damper is closed under the action of the spring, and the valve, under the action of the force of its spring, is in the lower position, which ensures the connection of the cavity above the piston with the atmosphere. Under the action of the force of spring on piston and air pressure on the mushroom of discharge valve, piston moves to the upper position, and the receiver cavity communicates with the atmosphere. When air bleed is turned on in the air system of an airplane or helicopter, a pressure difference occurs on valve. Under the influence of the air pressure difference, the valve opens and with its cam lifts the valve stem, closing the connection of the cavity above the piston with the atmosphere and opening access to air from the compressor cavity above the piston. Under the air pressure, the piston moves downwards. Model was created in Siemens NX.
