<p>The system has a base plate (1) and a guide housing (2), where an air gap (10) is provided between the plate and the housing. A piston (3) is guided into the housing, and permanent magnets (5, 6) are operative between the plate and piston to form an additional support for a load (4). The magnet (5) is connected with the plate by a rod (51) that is passed through an opening of the magnet (6) that is ring shaped. The support is replaced or supplemented by a load plate (7), where an upper swivel joint is provided for connecting the load plate with the piston.</p> |
