Device for guiding and centering a machine component

Device for guiding and centering a machine element (4, 7) which carries out oscillating linear motions in the direction of its central axis (2), wherein the machine element (4, 7) is supported in a housing (10) on two guides (11, 12) disposed in the direction of the central axis (2) at a distance one from the other, characterized in that each of the two guides (11, 12) comprises several plate-form spring elements (15) which are disposed in a plane (13, 14) at approximately right angles to the central axis (2) of the machine element (4, 7), each of the spring elements (15), on the one hand, is fixedly connected in the region of the central axis (2) with the machine element (4, 7) and, on the other hand, in the region of the outer ends of the spring elements (15) with the housing (10), each of the spring elements (15) including at least one long main spring part (16) which is disposed in the plane (13, 14) at right angles to the central axis (2) and at each end directed toward the housing (10) at least one short auxiliary spring part (17) which is disposed approximately parallel to the central axis (2), between each auxiliary spring part (17) and the associated main spring part (16) a connection element (18) is disposed, and the auxiliary spring parts (17) are rigidly connected via these connection elements (18) with the outer ends (24, 25) of the main spring parts (16).
