Shock absorber provided with a piston having a number of constantly open connecting channels which connect the two sides of the piston, and having a number of connecting channels to be opened and closed by element of a valve. The valve includes a plate valve which under the influence of flow therethrough, i.e. the pressure difference over the piston, on the outward movement of the shock absorber can be closed to a greater or lesser extent. On the inward movement, unimpeded flow of fluid through the piston can occur. A flow-through path is bounded by the corresponding connecting channels and the valve together with the upper side of the piston. In the rest position there is a flow-through possibility for fluid when the shock absorber fixings move away from each other, and when the shock absorber fixings move away from each other more quickly the flow-through cross section gradually decreases until the valve closes completely. |
