Abstract: A high-speed hydraulic press comprises a driving system including a cylinder having a sealed piston mounted slidably thereon, said piston being integral with a piston rod which is provided with a follow-up multiplicating sleeve having faces which form, on one side, at least one working chamber for rapid motion and, on the other side, a main working chamber for working motion of the press. The working chamber preferably is connected to a hydraulic supply system through a conduit fitted with a check valve enabling pressure multiplication in the chambers during the working motion of the piston. The follow-up sleeve preferably has a peripheral flange of which one face forms the main working chamber and is provided with at least one projection. The working chamber, as well as the main working chamber are preferably connected to one supply system.
