Abstract

The invention relates to a rotary device for an attachment on a machine, comprising a rotator (14) which has a stator (20), preferably held non-rotatably in a housing (12), and a rotor (24) which can be rotated about the stator (20) preferably by means of a worm gear unit (24, 30), and comprising a rotary transmission leadthrough (16) which passes through the rotator (14) and is intended for conducting a pressure medium via at least one media passage (40). According to the invention, it is proposed that the at least one media passage (40) has a first passage section (42) which is directed through the stator (20) and a second passage section (44) which communicates with said first passage section (42) and is continued via the rotary transmission leadthrough (16).
