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 means of a valve. The valve comprises a plate valve which under the influence of the flow through the valve, 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. By providing a number of channels in which the position of the clamping point of the valve is different for each of the openings of said channels, a very gradually rising damping characteristic can be obtained. |
