Abstract

A fluid power operate gripper has a housing, in which a drive space is located, which contains at least two drive pistons connected or able to be connected with a respective gripping element. The drive pistons divide up the drive space into a plurality of actuating chambers, which are subject to an actuating fluid under the control of control means in a controlled mutually matching manner. Since the drive pistons are not mechanically coupled kinematically variable operation is made possible in this manner.
