A DAMPING UNIT

In a damper for a steering device of a motor vehicle and more particularly a motor cycle a piston rod (3) is axially movable with respect to the cylinder. The piston rod is provided with a piston (2) inside the cylinder. The piston is provided with axial bores (6). The axial bores open into valve se...

Beschreibung
Zusammenfassung:	In a damper for a steering device of a motor vehicle and more particularly a motor cycle a piston rod (3) is axially movable with respect to the cylinder. The piston rod is provided with a piston (2) inside the cylinder. The piston is provided with axial bores (6). The axial bores open into valve seat faces (17c) of the piston. Valve rings (9, 10) are allocated to the valve seat faces. Helical compression springs (11) are located within the bores. These springs urge the valve rings towards respective opening positions illustrated in the figure. The valve rings are movable towards respective damping positions in response to the axial movement of the piston rod with respect to the cylinder. The valve rings have valve faces (21) opposite to respective valve seat faces. The valve faces are provided with projections (30) towards the valve seat faces and with recesses (23, 13) adjacent these projections. So, a restricted fluid communication is obtained in the damping position of the respective valve ring.
