Abstract

A shock absorber of the telescopic type that includes two cylinders, one external and one internal, closed at one end by a head common to both and whose outer cylinder is closed at its other end by a tip, while the other the end of the inner cylinder is closed by a valve body that faces the endpiece and that delimits a bottom space that communicates with the intermediate space between the two cylinders; wherein a piston provided with a shank sealingly passes through the head, said piston dividing said inner cylinder into a first chamber of variable volume on the side of the head and a second chamber of variable volume on the side of the head. Valve body and having, both in the piston and in the valve body, two circular rows of axial conduits for the passage of the hydraulic fluid, each controlled by some shutters that surround the outlet of the conduits, the conduits being throttled axially made in the piston for the transfer of the fluid from the second to the first chamber and in a similar way also throttled the axial conduits made in the valve body for the transfer of the fluid from the first chamber to the bottom space, characterized in that the obturator (48, 88) of the conduits (42, 84) of the piston (22) or of the valve body (16), or both, are a disc pack consists of at least two annular discs of which a first disc (48a, 88a), which is closest to the outlet of the conduits (42, 84) can be coupled by its periphery to a seat (46, 90) surrounding the annular row of conduits and having a recess (60) therein, and a second disc (48b, 88b) adjacent to the first disc (48a, 88a) has at least one peripheral incision (68) communicating permanently with said recess (60), and in which, adjacent to the face of the second disc (48b, 88b) on the side opposite to that facing the first disc (48a, 88a), there is a cap (52, 94) in which at least the periphery is coupled to the periphery of the second disk (48b, 88b).
