Abstract
The device permits the precise guiding and centering of machine elements, for example of a piston rod (7) or a piston (3,4) in a cylinder (5,6). Therein two guides (11,12) are disposed at approximately right angles to the longitudinal axis (2) of the piston rod (7) and at a distance from each other. Each guide (11,12) comprises several spring elements (15) which extend radially from the axis (2). The spring elements (15) comprise long main spring parts (16) and short auxiliary spring (17). The spring parts (16,17) are rigidly connected one with the other via connection parts (18). The guides (11,12) have with respect to the axis (2) high transverse rigidity and permit precisely guided oscillating motions of the machine elements (3,4,5,6,7) along the longitudinal axis (2). These guides (11,12) permit for example the contact-free relative motions between piston (3,4) and cylinder (5,6) and have a high service life and operational reliability.
