The hydraulic unit comprises three cylinder units, each with a piston and cylinder. Each of the cylinder units through insertion of pressure fluid into the cylinder space effects a work movement to an effective position, alternatively through draining of the cylinder space executes a return movement to a return position. The first cylinder unit (35,46) has its one part (35) joined to a part (34) of a mechanical retention device and its other part (46) joined with one of the parts (40) of the other cylinder unit (40,41,47). - This part is joined to a part (36) of fixture parts and with the one part to a third cylinder unit with the remaining other parts to the second and third cylinder units joined with the remaining part (26) of the mechanical retention device. |
