Perfections in hydraulic jacks, characterized in that the oil tank is included between the body of the apparatus and a cylinder concentric to it, through which the force piston slides by the pressure of the oil, which absorbed by a pair of side pumps and driven by the piston of these through directional valves, passes to the chamber of the cylinder by raising the piston, to lower which will be sufficient to act a screw arranged outside the main body and whose conical tip normally intercepts the return conduit of the liquid to your deposit.
