Abstract: A vibration and displacement damper includes a plunger piston (10) sliding with a slight clearance inside a guiding cylinder (20). The plunger piston includes over a part of its length a piston ring (12) sliding inside a main chamber (13) provided in the cylinder, the ring including calibrated through-orifices (14) for a high-viscosity fluid filling the chamber on both sides of the ring. The device is intended to damp vibrations and displacements, in particular of cable stays.

Abstract: This invention relates to a process and a device for the damping of motion between two cylindrical parts sliding with one another in translation and friction. According to this invention, the damping is performed by the application of a force exerted radially perpendicularly to the translation motion of the two parts by at least one elastic segment (13) circling one of the parts (11) and inside the other (12), integral in translation with one of the parts (11) and appplying said frictional force on the other part (12). This invention is applicable to the absorption of shocks as well as to that of vibrations.

Abstract: A piston-cylinder arrangement, in particular a shock absorber (1), has a housing (2) as well as a piston (3) guided therein and pushed against a damping medium, and on which a piston rod (5) acts. The shock absorber has a screw-in-plug (10), within which a position transmitter (19), constructed as a proximity sensor, is housed. The screw-in plug with the proximity sensor (19) located therein and evaluation electronics are arranged coaxially on the rear end of the shock absorber housing (2). The piston is connected on the rear end to a magnet (15), and the proximity sensor is constructed of at least one magnetic field-dependent sensor.
