Abstract

Improvements in the construction of hydraulic presses, with two pistons arranged coaxially, acting successively, working as a working piston, or reduction piston in separate cylinder enclosures, and from which the reduction piston constituted as a stepped piston can penetrate with its part of smaller diameter in the cylinder of the working piston, characterized in that the cylinder enclosures of both pistons are arranged in a cylindrical body which has in its envelope channels for the supply and evacuation of the pressure medium and are separated by a partition, which has a bore in which, or through which the part of the reduction piston having smaller diameter penetrates, and in which a connection conduit is provided, maneuvered during the movement of the reduction piston, between the medium inlet opening of active pressure in the advance and the cylinder space of the piston of tr down loaded during the advancement of the demultipliation piston.
