A hydro-pneumatic pressure transformer, comprising, a unit housing, a work chamber (3), disposed in said unit housing, for fluctuating pressures, namely a low storage pressure and a high work pressure, a working piston (2), delimits the work chamber (3) at a front end and is actuatable by a work pressure in the unit housing (1) for its work stroke, which piston extends to an exterior by means of a piston rod (4), a storage chamber (9) is hydraulically connected with the work chamber (3) and is disposed in a casing (13), from which hydraulic oil under storage pressure flows into the work chamber (3) during a rapid movement of a work stroke and flows back again during a return stroke, a plunger piston (21) is hydraulically actuatable to provide a high pressure generator, which dips into the work chamber (3) after a rapid movement of the working piston (2), a storage piston (11) which delimits the storage chamber (9), is displaceable in the casing (13) and is penetrated by the plunger piston (21) and is radially sealed against the plunger piston (21) as well as the casing (13), a control chamber (12) on one side of the storage piston (11) faces away from the storage chamber (9), which is charged with air at different pressures, and a separating wall (15), delimits the control chamber (12) and is fixedly connected with the casing (13) and penetrated by the plunger piston (21), said separating wall is provided with radially outward leading connecting conduits (27, 28) for compressed air control, a pressure-relieving outer annular groove (38) in storage piston (11) is provided in the stroke direction between the radial seals (36, 34) for the absolute separation of oil from water, and an inner annular groove (42) is provided, between the radial seals (37), in the wall of the inner bore (41) penetrated by the plunger piston (21).
