Abstract

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.
