Abstract
A clamping device includes a base body defining at least a portion of at least one pressure chamber, which has at least one opening oriented in a direction of action. A membrane is connected with the base body in a pressure-tight manner and seals the at least one opening in the direction of action. The membrane defines a first side wall section of the pressure chamber. A movable second side wall section partially delimits the pressure chamber and a constant amount of pressure fluid is sealed in the pressure chamber. At least one mechanical actuator displaces or deforms the second side wall section in order to cause the membrane to outwardly bulge.
