摘要： A hydraulic shock absorber comprising a main tube divided, by a piston-rod extending through the extension chamber. The shock absorber is further provided with a hydraulic rebound stop, called HRS fixed in the extension chamber and comprising a HRS-tube restricting the main tube, bottom and an 10 entry. The HRS also has HRS-piston freely slidably mounted on the rod and having a diameter adjusted to the HRS-tube and being provided with at least one fluid-passage substantially axially oriented. The axial displacements of the HRS-piston are limited between a Rebound-stop and a HRS-ring, both fixed to the rod. The fluid-passage is open to a flow of fluid when in abutment against the HRS-ring and being sealed when in abutment against the Rebound-stop. The HRS is further provided with at least one fluid-passage connecting the HRS-chamber to the extension chamber and providing to the fluid a way-out for an exiting flow generating a HRS-damping which is tunable and varies as the HRS-piston penetrates the HRS-tube, their relative position determining the size of the way-out.

摘要： The invention relates to a hydraulic damper, in particular for the suspension system of a motor vehicle, comprising a tube filled with working fluid; a piston assembly slidably positioned inside the tube; a fluid compensation chamber located outside of the tube, and a base valve assembly at the end of the tube for controlling the flow of working fluid between the tube and the compensation chamber. A compression valve module added between the piston assembly and the base valve assembly allows the damping to increase during extremely fast compression strokes without modification of the other damper components, affecting neither tuning options nor performance in a normal operating range of piston velocities.

摘要： A hydraulic damper (1) includes a tube (3) filled with working liquid, wherein at least one end of the tube (3) is provided with a narrower section (31) of a smaller diameter provided with at least one axial groove (12). The damper (1) includes at least one additional piston assembly (13) having diameter (D3) smaller than diameter (D1) of the main section of the tube (3), displaceable along with the main piston assembly (4) and apt to be introduced in the narrower section of the tube (3) to generate additional damping force. The narrower section (31) extends through a conical section (32) into the main section (33) of the tube (3) and the conical section (32) of the tube (3) is internally shaped to form axial bridges (15) defining said axial grooves (12) extending along the length of said conical section (32), each comprising a cylindrical section (151).
