Abstract: A piston assembly for a damper includes: a piston head; a piston rod having one end connected to the piston head, forming an inner space therein, and having another end at which an opening communicating with the inner space is formed; a wire having one end connected to an electric device mounted on the piston head and extending through the inner space of the piston rod; and a connector disposed at the other end of the piston rod and connected to another end of the wire. The connector includes a socket part rotatably disposed in the opening at the other end of the piston rod, and a plug part inserted into the socket through the opening of the other end of the piston rod. A self-alignment structure is provided in the socket part and the plug part and is configured to rotate the socket part such that the socket part is aligned at a predetermined orientation with respect to the plug part when the plug part is inserted into the socket part.

Abstract: The present disclosure relates to a damping force variable valve assembly, which is installed in a damping force variable shock absorber for adjustment of a damping force of the shock absorber, includes at least: a solenoid that generates a magnetic force when an electric current is supplied thereto; a plunger configured to be moved by the magnetic force of the solenoid; a spool that is moved together with the plunger and change a damping force between a hard mode and a soft mode by changing an inner passage of the damping force variable valve assembly; and a spool position determination member that locates the spool at a fail position, which does not correspond to the hard mode and the soft mode, so as to maintain the damping force of the shock absorber at a medium level between the hard mode and the soft mode upon fail of the solenoid.
