Abstract
An air discharge system for an aviation turbomachine compressor is disclosed. The discharge system includes at least one discharge valve. Each valve includes a valve body suitable for moving between an open position and a closed position of the discharge valve, a camshaft including a cylindrical rod carrying a cam mounted to bear against the valve body in such a manner that rotating the camshaft causes the valve body to move between its open and closed positions, and a device for keeping the cam bearing permanently against the valve body. The discharge system further includes at least one main electric motor having its rotor suitable for driving the camshaft of each discharge valve in rotation, and an electronic control system for controlling each main electric motor.
