PCT No. PCT/SE94/01167 Sec. 371 Date Jul. 15, 1996 Sec. 102(e) Date Jul. 15, 1996 PCT Filed Dec. 5, 1994 PCT Pub. No. WO95/16499 PCT Pub. Date Jun. 22, 1995The invention relates to a monitor for ejecting jets of water, foam or mist, comprising a pipe system attached to a foot support, which is rotatable on the support. The foot support is characterized by a lower disc-shaped part (10), an upper part (13), which is rotatable with respect to the lower part (10), and a fastening ring (15) which presses a flange (14) of the upper part (13) against the lower part (10). The invention consists of arranging through-holes in the upper part (13) from the central hole to the gap between the fastening ring (15) and the flange (14). A hydrostatic bearing between the flange (14) and the fastening ring (15) has been brought about so that the flange and the upper part (13) can be easily rotated.
