Abstract

The rotary device comprises a rotary unit (1) that is made up of a stator (2), rotor (3) and a rotary drive (4). There is a duct (17, 18) linked to the rotor and having a first section (17) and a rigid second section (18) with a sealed channel connector (27, 31, 32) located between the two sections for throughput of compressed oil and/or electrical charge for supplying working means such as a claw, saw and pincers, as well as having a brake or blocking system (55 to 62) to intermittently adjust the rotor opposite the stator. The duct, comprising the rigid section built as a separate section in front of the stator and rotor, has a central recess (15, 16) inserted in the rotary unit. The first section of the duct may be built as a cylinder (17) whilst the second section may be built as a sleeve (18). The first section may have an axial channel (23) and the second section may have a radial channel (32), with the radial channel of the second section being connected to the axial channel of the first section by means of a plate channel (27, 31).
