Improvements in the hydraulic steels, particularly those for mines whose internal tempering is guided axially displaceable in an outer wall that forms the pressure chamber with the intercalation of joint means characterized by the interior and the exterior cladding that surround it by means of a rubber sleeve. Flexible material - particularly elastically deformable - fluid-tight guide in the form of a sleeve and which in the relative movement of the parts of the saddle executes a rolling movement in the inside and outside.
