Abstract

The invention relates to an articulated joint for the articulating connection of two joint bodies, having a first bearing body disposed in a bore of one of the joint bodies for rotation therewith and provided internally with a first spherical bearing surface, having a second bearing body joined with the other joint body for rotation therewith and having a second spherical outer bearing surface in contact with the first bearing surface, and having at least two fluid pathways leading through the two joint bodies and the bearing bodies for at least one fluid and having gaskets for sealing off the fluid pathways. Each fluid pathway has a recess formed in the bearing surface of the bearing body, and a passage being associated to one of the recesses and formed in the bearing surface of the other bearing body. Furthermore, stops are provided for establishing a permissible articulating range of both of the joint bodies such that each passage will open into the associated one of these recesses in all possible articulated positions of the joint bodies within this range.
