Abstract (en)
[origin: EP1055466A2] The hydraulic unit has a holding down device drive (20) with a piston-cylinder-unit, which is carried by the piston rod (8) the plunger drive (2). The pressure chamber (32) of the drive is connected to the second working chamber of the plunger drive vi flow connection (34). To generate holding-down force, pressure from the second working chamber (14) of the plunger drive is transferred to the pressure chamber of the holding down device drive.
