Patent

CA 2517332

The invention relates to a rotating or pivoting device (110) comprising a housing (12), at least one working piston (14) which is mounted in the housing and subjected to a pressure medium, and a pivoting part (20) which is rotatably mounted in the housing and is rotatably driven by the working piston by means of a rotating coupling mechanism, said working piston being mounted in the housing in such a way that it can be displaced in a housing-side cylinder. The inventive rotating or pivoting device also comprises an abutment part (114) that limits the stroke of the working cylinder in at least two positions and can be locked at least in its axially inner intermediate position. Said abutment part is provided with a locking piston (120) that is mounted in such a way that it can be axially displaced, and, when the abutment part is in its intermediate position, can be displaced against a spring element (122) in a pressurised manner into a locking position, and, in the locking position, activates locking means (128) for locking the abutment part (114).

La présente invention concerne un dispositif de rotation ou de pivotement (110) comprenant: un boîtier (12); au moins un piston actif (14) disposé dans le boîtier et soumis à l'action d'un agent de compression; une partie de pivotement (20) entraînée en rotation par le piston actif par l'intermédiaire d'un couplage en rotation, ladite partie de pivotement étant montée rotatif dans le boîtier, le piston actif étant monté pour pouvoir se déplacer dans un cylindre côté boîtier; une partie d'arrêt (114) qui limite la course du cylindre actif dans au moins deux positions et qui peut être bloquée au moins dans sa position intermédiaire située vers l'intérieur d'un point de vue axial, la partie d'arrêt comprenant un piston de blocage (120) qui est monté pour pouvoir effectuer un mouvement axial, qui peut, lorsque la partie d'arrêt se trouve dans sa position intermédiaire, se déplacer contre des éléments de rappel (122) sous l'action de la pression, pour prendre une position de blocage, et qui, lorsqu'il se trouve dans sa position de blocage, active des éléments de blocage (128) afin de bloquer la partie d'arrêt (114).
