Abstract
A shock absorber of the telescopic type that includes two cylinders, one outer and one inner, 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 end of the cylinder the interior 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 the piston and the valve body, two circular rows of axial conduits for the passage of hydraulic fluid, each controlled by a few shutters that surround the outlet of the conduits, the thrust pipes being throttled 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 shutter (48, 188) of the conduits (42, 84) of the piston (22) or of the valve body (16), or both, are constituted os by a disk pack formed by at least two annular disks of which a first disk (48a; 188a) that is closest to the outlet of the conduits (42; 84) can be coupled by its periphery to a seat (46; 90) that surrounds the annular row of conduits and that inside it has a recess (60; 160), and a second disk (48b; 188b) adjacent to the first disk, (48a; 188a) has at least one peripheral incision (68; 168) that communicates permanently with said recess (60; 160), and in the that, adjacent to the face of the second disk (48b; 188b) on the side opposite to that facing the first disk (48a; 188a), there is a cap (52; 194), in which at least the periphery is coupled to the periphery of the second disk (48b; 188b).
