Abstract

A linear adjusting device, especially for cryogenic temperatures and under vacuum conditions, having an adjusting body being adjustable on a carrier body along a linear adjusting path and supported by more than one bending springs placed between said carrier body and adjusting body and bent to have a U-like shape, the U-legs of each of the U-shaped bending springs extending longitudinally along the adjusting path, and at their free ends, one of the legs of each bending spring is fixed to said carrier body and the other leg to said adjusting body, said bending springs being arranged in at least two groups of bending springs consisting of at least two bending springs spaced apart by a given distance along said adjusting path, the bending springs of at least one of said groups of bending springs are arranged at oblique angles to the bending springs of another group of bending springs, when seen in a cross section perpendicular to said adjusting path (FIG. 1).
