Abstract
A drive mechanism for the movement of an object along an axis of motion comprises two clamping elements and a drive element disposed between the two clamping elements which enables a relative movement of the two clamping elements along the axis of motion. Each clamping element comprises a base body and two clamping jaws, wherein a piezo-actuator is disposed between the base body and at least one of the two clamping jaws, which can produce a clamping force acting on the object which is directed transversely to the axis of motion. The base bodies of the two clamping elements are connected by at least two expansible elements. The drive element comprises a further piezo-actuator, which enables the relative displacement of the two clamping elements along the axis of motion. The drive mechanism is suitable for application in a micro-valve.
