| Zusammenfassung: | The unit is for the synchronisation of two or more parts, esp. for hydraulic or pneumatic piston-cylinder servo drives. Two or more servo drives are positioned in series in an integral system, so that the relative movements between the pistons and cylinders of all drives are synchronised. When operational, the drives are connected to the outer annular pistons so that the movement of these parts is controlled and synchronised. Each cylinder is movable relative to a piston and each is connected to one of the parts. The system contains connection lines so that each side of each piston is connected to corresp. opposite sides of the piston is the neighbouring piston cylinder units.
L'invention concerne un appareil de synchronisation des mouvements de plusieurs éléments, notamment de vérins. L'appareil comprend deux ensembles cylindres-pistons ou plus, qui sont reliés en série dans un système hydraulique ou pneumatiques 27 à boucle fermée de manière que les mouvements relatifs entre les pistons 21, 21a, 21b et cylindres 20, 20a, 20b de tous les ensembles précités soient synchronisés, lesdits ensembles cylindres-pistons étant agencés en fonctionnement pour être accouplés auxdits deux éléments ou plus 14, 14a, 14b en vue de commander et de synchroniser tous mouvements desdits éléments. Application aux inverseurs de poussée de réacteurs. |
