Abstract

A new jack that being of the displacement of its piston is carried out by the oil pressure supplied by a gear pump, nothing is essentially characterized in that the oil supply chamber is established perimetrally with respect to the cylindrical body corresponding to the pressure chamber, it being provided that the sliding piston inside said pressure chamber is integral with a second cylinder in which, with the collaboration of a second secondary piston, a second pressure chamber is established, communicated with the first through of an axial hole in the main piston, all in such a way that the gear pump takes oil from the supply chamber and sends it to the main pressure chamber, causing the main displacement, after which displacement the oil access is initiated to the secondary chamber for the displacement, of a second operational phase of the jack, of the piston secu standard.
