ABSTRACT:
A support element for supporting or holding a work piece on a mounting surface, for example in a machine tool, has a support or pin movably mounted in a housing. The pin is moved into contact with a work piece by an airstream, held in work piece contact by a hydraulic piston, and reset into a starting position by at least one spring, whereby the work piece is contacted gently under a manual throttle control of the airstream, but firmly held in place by hydraulic pressure.
