ABSTRACT:
A short-stroke clamping element for exerting a holding force on a workpiece has the form of a bar with an internal pressure chamber, and is adapted to produce the clamping force in a direction normal to its length. The pressure chamber, which is adapted to have fluid under pressure supplied to it, is confined by peripheral and terminal walls. The chamber runs from one end of the bar to the other, one of such peripheral walls forming a clamping jaw constituted by an outwardly moving wall of said chamber and able to bulge outwards under the action of such pressure fluid.
