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 arrang ed 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 lea st 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) i n 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 groo ve (61) for co-action with one (54) of the rotor shaft (31) channels.

Claims (11)

1. A rotator, particularly intended for arm-carried working appliances, wherein the rotator (10) includes a stator (20), a rotor (30) and a swivel coupling/swivel device (50) for the transfer of working medium between stator (20) and rotor (30), characterised in that the swivel device (50) is arranged within the rotor (30).
2. A rotator according to Claim 1, characterised in that said rotator includes an upper stator wall (21) which carries an outwardly projecting portion (60) that forms a part of the swivel device (50).
3. A rotator according to Claim 1 or 2, characterised in that the rotor shaft (31) includes a recess (51) which forms part of the swivel device (50).
4. A rotator according to any one of Claims 1-3, characterised in that the rotor shaft (31) includes at least one medium transfer channel (54) that connects at least partially radially with a recess (51) in the rotor shaft (31).
5. A rotator according to any one of Claims 1-4, characterised in that the rotor shaft (31) includes a channel (52) that connects generally axially with a recess (51) in the rotor shaft (31).
6. A rotator according to any one of Claims 2-5, characterised in that 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 channels.
7. A rotator according to any one of Claims 1-6, characterised in that the rotor shaft (31) includes a channel (54) which has a generally radial part (54a) and a generally axial part (54b).
8. A rotator according to any one of Claims 1-7, characterised in that the rotor shaft (31) includes a generally axial channel (52) which extends from a bottom surface (71) of a recess (51) in the rotor shaft (31) to the lower end (38) of said rotor shaft.
9. A rotator according to any one of Claims 4-8, characterised in that the rotor shaft channels (52,54) extend to connection points (80,82) in the lower end surface (38) of the rotor shaft (31) and/or to radial connection points (81,83) in a clamping ring (100) on the rotor shaft.
10. A rotator according to any one of Claims 3-9, characterised by a gap or a space (70) between a bottom surface of the downwardly projecting portion (60) of the upper stator wall (21) and a bottom surface (71) of the rotor shaft recess (51).
11. A rotator according to any one of Claims 1-10, characterised in that the upper stator wall (21) includes connection points (76,77) and/or channels (62,63) that communicate with the channels (52,54) of the rotor shaft (31).
