The present invention relates to a rotator arrangement, particularly for arm- carried working appliances, wherein the rotator (10) includes a stator (20), a rotor (30) and a swivel coupling/swivel device (50) for medium transfer between stator (20) and rotor (30), wherein the swivel device (50) is arranged within the rotor (30). The rotator (10) includes an upper stator wall (21), which carries an outwardly projecting portion (60) that forms a part of the swivel device (50), and the rotor shaft (31) has a recess (51) which also forms a part of the swivel device (50). The rotor shaft (31) includes at least one working medium transfer channel (54) that connects at least partially radially with a recess (51) in the rotor shaft (31). The rotor shaft (31) includes a channel (52) that connects generally axially with a recess (51) in the rotor shaft (31). The outwardly projecting portion (60) of the upper stator wall (21) and/or the rotor shaft (31) includes at least one ring groove (61) for co-action with one (54) of the rotor shaft (31) channels.
La présente invention concerne un système rotateur destiné notamment à des outils de travail à bras-support. Le rotateur (10) comprend un stator (20), un rotor (30) et un couplage articulé/dispositif pivotant (50) destiné au transfert d'un agent entre le stator (20) et le rotor (30). Le dispositif pivotant (50) est placé dans le rotor (30). Le rotateur (10) comprend une paroi stator supérieure (21) qui porte une partie en saillie vers l'extérieur (60), laquelle constitue une partie du dispositif pivotant (50) et l'arbre rotor (31) a un évidement (51) qui constitue également une partie du dispositif pivotant (50). L'arbre rotor (31) comprend au moins un canal (54) qui est destiné au transfert de l'agent de travail (54) et est radialement et au moins partiellement relié à un évidement (51) de l'arbre rotor (31). Le partie en saillie vers l'extérieur (60) de la paroi stator supérieure (21) et/ou de l'arbre rotor (31) comprend au moins une gorge (61) destinée à la coopération avec un (54) des canaux de l'arbre rotor (31).
