Closing and locking device for thrust reverser doors

The reverser has a closing/locking device (10) with a bolt (21) for locking a valve (12). The bolt has a latch (22) cooperating with a locking interface (28) to maintain the valve closed. The latch delays the interface towards its closing position to realize the closing of the valve with the energy supplied by a motor. The motor is connected to the latch by an irreversible transmission to oppose the opening of the latch.
