An apparatus for moving an operating element has a guide surface along which the operating element may be guided. A drive means provides a driving pulse exerted on the operating element for the movement of the operating element along the guide surface. A gap between the guide surface and the outer surface of the operating element is filled by a layer of a material that acts as an adhesive layer when the operating element is at rest and as a lubricating layer when the operating element is in motion. The outside of the operating element may have a conical profile and the guide surface may have a cylindrical profile, with the gap between the guide surface and the outer surface of the operating element becoming progressively larger in the direction of movement of the operating element. The layer of material in the gap may be a dry or solid lubricant, comprising material such as MoS2 or polytetrafluoroethylene.
An apparatus comprising an operating element, a guide surface that extends around the operating element and along which the operating element may be guided, and a drive means that provides a driving pulse exerted on the operating element for the movement of the operating element along the guide surface, a gap is located between the guide surface and an outer surface of the operating element, a material means disposed in the gap acts as an adhesive when the operating element is at rest and as a lubricant when the operating element is in motion.
