Self-contained workpiece-holding device, preferably equip- ped with an operating system, and also advantageously pro- vided with individual power-cylinder operating means for operating it at an independent pressure" ABSTRACT OF THE DISCLOSURE The invention relates to a workpiece-holding device provided with fastening means for fastening, by tightening, clamping or the like, the workpiece through the medium of compressed-fluid power-cylinders incorporated in the device, fed from the fluid pressure generator actuated by a source of power comprising said pressure generator incorporated in the device, the source of power being also advantageously incorporated in the device which is thereby self-contained and of reduced overall dimensions. Moreover, at least one valve assembly for the delivery of compressed fluid from the pressure generator at a predetermined pressure may be asso- ciated individually with one of the power-cylinders so that each power-cylinder operates either at a pressure indepen- dent of the operating pressure of the other power-cylinders or at different times. The invention is useful particularly for machines.
