    摘要： The pressfitting collar (10), for pipe pressing tongs, comprises at least two jaws (12, 14, 16) hinged together, each comprising an arched pressfitting element (20, 21, 22) with a radius of curvature suitable for the pipe joint to be made. The facing end edges (24, 25) of the pressfitting elements (20, 22) of the two end jaws (12, 16) have respective shaped profiles which mate on completion of the pressfitting operation. The profiles of the two end edges (24, 25) are shaped completely as consecutive triangular teeth. The straight line (L 1 ) joining the vertices of two consecutive triangular teeth of one (25) of the two edge profiles coincides with, or passes a certain distance beyond, the straight line (L 2 ) joining the vertices of two corresponding consecutive triangular teeth of the other edge profile (24).

    摘要： A pipe bending apparatus with hydraulic transmission, operable with one hand, of the type comprising a cylinder (5,8,50,6) in which there is movable in both directions a die-carrying rod (1), comprises, fixed in correspondence with that (3) of its ends located within the cylinder, a seal element (4) defining together with portions of the walls of said cylinder a first and a second chamber (43,52) of volume variable in relation to the movements of said rod, said chambers being connected via conduits (21,36,56,53A,53B) and at least one intermediate chamber (23) to a reservoir (11) for a fluid. The intermediate chamber (22,23,24) comprises a hydraulic pump operable by one hand, and unidirectional valve means (22,24). The reservoir (11) comprises an at least partly deformable sealing wall (12).
