The pumps 6 and 10 are driven by a common motor 7, the volume and direction of the output of the pump 6 being controlled by means 8. The pump 6 may be a pivotable axial plunger pump which recovers the kinetic energy liberated during deceleration of the ram 1 by acting as an hydraulic motor which acts conjointly with the motor 7 to drive the pump 10. A device 11 may compensate for the weight of the ram 1. The pump 6 is connected continuously to the units 2 during operation of the press whereas the accumulator 9 is connectable temporarily to the unit 5 during movement of the ram 1 in its work stroke direction.
