element 3 as soon as moving element 4 is displaced from its rest position to the extent that at least one of the passages 6 in the direction of movement x is positioned adjacent to closed cylinder shell section 7 valve 1 will have a through flow path running through the relevant passage or passages 6 with its through flow cross section restricted by the cross section of the relevant passages 6 and depending on the displacement of moving element 4 and possibly also by the closed cylinder shell section 7 which depending on the excursion of valve 1 from its rest position may cover part of the cross section of at least one of the passages 6 as shown in fig1 valve 1 according to the invention has several passages 6 with different cross sections and with their centres offset from each other in the direction of movement x the through flow cross section of the through flow path will therefore change depending on how far valve 1 and thus moving element 4 are displaced from rest position the through flow cross section of the through flow path is thereby adjustable via the excursion of valve 1 from rest position fig1 b schematically illustrates a cross section of an embodiment of valve 1 according to the invention analogous to fig1 a the embodiment shown in fig1 b essentially corresponds to the embodiment shown in fig1 a wherein however the embodiment shown in fig1 b has been altered a way to include sealing element 14 a damping chamber 12 and a damping bypass 13.
