<p>HOMOKINETIC TRANSMISSION The invention provides a substantially homokinetic transmission for rotationally connecting two shafts (13,15) one of which (13) is mounted on a fixed support (11) and the other of which (15) is mounted on a movable support (10) so that its inclination is variable, and comprises two pairs of universal joints (18,19 and 21,22) each interconnected by a connector of variable length (27,29) one pair attached to one of the shafts and the other attached to the other of the shafts; an intermediate shaft (24) of fixed length is interposed between the two pairs of universal joints and this is carried by a third support (25) pivotally mounted on the fixed support, and control means (29) are provided for controlling the inclination of the intermediate shaft in relation to the position of the shaft which has a variable inclination. The invention is particularly applicable to a dredger which comprises a floating hull and a boom of variable inclination, where it is desired to drive a pump or the like at the end of the boom with a motor on the hull.
