Apparatus for the displacement of thrust reversers of two jet engines of an airplane

Apparatus for the synchronized displacement of two thrust reversers for two jet engines of an airplane, comprising first and second system means for displacing respective thrust reversers, each system means including a compressed air motor means;

• valve means for controlling the operation of said motor means by controlling the flow of compressed air thereto;
• and setter means connected to said valve means for operating said valve means for controlling the displacement of the respective motor means;
• and synchronizing means for automatically synchronizing the displacement of the two thrust reversers including means for measuring displacements in the first and second system means at respective corresponding locations, comparing means for comparing the displacements measured in the first and second system means and means connected to the comparing means and to said setter means of said first and second system means for controlling the operation of said first and second motor means in response to the comparison of the displacements measured such that the displacements of the two thrust reversers by the respective motor means are automatically equalized.
