A machine part, in which a limited swingable motion can be carried out along a slide surface between a first element and a second element, means being provided for conducting a liquid from a point of the first element which is distant from the slide surface to a side of the second element which faces away from the slide surface, said means having channels or bore holes through both elements with a connecting passage on the slide surface between them, the bore hole in at least one of the two elements being widened at the connecting passage to form an elongated chamber in which there is arranged a flow-through body provided in axial direction with bore holes and axially under pressure, semi-spherical head ends of said flow-through body resting in sealing manner against two ends of the chamber.
