A damper system includes a cylinder wall defining a cylindrical chamber and having an open end having an annular recess. A piston is reciprocatingly disposed in the cylinder and is connected to a piston rod that extends out of the open end of the cylinder. An annular wiper seal is mounted in the annular recess of the cylinder and engages the piston rod. The annular wiper seal is made from a thermoplastic material. The annular wiper seal has an S-shaped cross section with a wiper lip having a lip edge that engages the piston rod, wherein the wiper lip has a substantially constant thickness along a majority of its length from the lip edge to the second radially inwardly extending portion.

A seal member includes a base portion held by a cylinder, the base portion being configured such that a rod is inserted through the base portion, and a lip portion provided on the base portion, the lip portion being brought into sliding contact with an outer circumference of the rod, wherein the lip portion is formed of an elastic body containing fibers oriented in the axial direction of the rod.

A frequency-selective damper valve includes a controlled flow channel providing a fluid connection between a first and second valve sides; a controlled valve assembly in a controlled flow channel; a movable valve body acting on the controlled valve assembly; and a variable volume chamber, the movable valve body interacting with the variable volume chamber such that movement of the movable valve body and a change in volume of the variable volume chamber are interrelated. The variable volume chamber includes an outlet opening, in operation, downstream of the controlled valve assembly and does not include an opening upstream of the controlled valve assembly with respect to a controlled fluid flow in the controlled flow channel, the outlet opening providing a flow resistance.

A shock absorber includes a cylinder and a piston. The piston is configured to partition an internal space of the cylinder into two oil chambers and is capable of sliding in an axial direction of the cylinder. The piston having formed therethrough a communication path configured to bring the two oil chambers into communication with each other. The shock absorber also includes a first rod and a second rod. The first rod extends in a first direction of the axial direction with respect to the piston. The second rod has a diameter larger than a diameter of the first rod, and extends in a second direction of the axial direction, which is opposite to the first direction, with respect to the piston. The shock absorber further includes a rod mounting member, which is provided on the first rod, and a cylinder mounting member, which is provided on the cylinder and arranged as offset from an axis of the cylinder.
