<p>Several e.m. devices are aligned towards the exciter body (12). A free mass (60) is supported in the exciter body to move in the longitudinal direction. The exciter body is provided with non-linear suspension members each mounted on the inside of an e.m. unit. - The free mass can be fully enclosed in an elongated housing which has two end caps (22,24) which each contain a cast magnet. These end caps can be separated from each otherby a housing tube fixed in between. The free mass is then pref. suspended equidistant from the end caps by elastomer shear springs.</p> |
