4 and 2 and 3 respectively move apart and the press jaws return under the action of compression springs 55 to their open position which is indicated by the double arrow 29 in back of the plane of drawing according to fig3 the platform 44 has a circular opening 56 on which a motor 57 is fastened by means of a flange 57a underneath the recess 56 a hydraulic pump 58 in the form of a submersible pump is flange mounted to the motor 57 this pump is connected by a control valve 59 and by hydraulic tubing indicated by broken lines to the individual hydraulic drives all of the hydraulic drive elements are contained within the case 45 as represented in fig3 so that not only is an extremely simple routing of the lines possible but also leakage can be disregarded fig4 shows the radial press with the press jaws in the closed position the distances between diametrically opposite press jaws whose working surfaces in this case make up a cylindrical surface are at a distance apart diameter that is indicated by the double arrow 60 it can also be seen that the upper cam follower body 31 and the bottom cam follower body 33 remain steady on the corresponding planar surfaces 12 and 13 respectively while the other two control bodies 32 and 34 have been pushed toward the press axis a under the action of the cam faces 1 4 and 2 3 respectively it can furthermore be seen that the tension armature 26 has a shoulder 61 which is situated in the seam between the two.
