Shock absorber (1,31) comprising a piston (3,33,103,133) inside which a sleeve (15,45) is present, which can be operated separately from the piston. This sleeve is provided with through-flow conduits which can cooperate with apertures, which are fitted at a vertical distance, of a part of the piston in order to provide an auxiliary flow when the piston is displaced in the cylinder (2,32,102). Such auxiliary flow enters into a chamber which is delimited by one or more spring plates (16,46), which act on a sleeve (15,45), which loads the main valve against opening when it is pressed down by the spring plate. By filling the chamber with fluid, the load applied on the sleeve by the spring plate is reduced and the load on the main valve decreases, as a result of which the latter opens more readily. |
