<p>A rotary coupling for transmitting electric current and fluid between a rotating (2) and a stationary (1) body. The electric current is transmitted by way of slip rings (15) provided on an insulating sleeve (8). In axial grooves (12) of the sleeve elongated electric connection strips (17) are provided. Electrically conducting slip rings (15) and insulating spacer rings (16) are thread alternately over the sleeve. Each slip ring is electrically and mechanically connected with a separate strip (17) and each strip is electrically connected with conductors (18) arranged within the stationary body. Current conductors (4) are fixed to the rotating body. Each current conductor is in sliding electrical contact with a corresponding slip ring. The fluid is transmitted with a nipple (21) connected to a fluid hose (20). The nipple presents a throat (24) around which a sleeve (25) connected with the rotary body is tight and rotatingly mounted. </p> |
