Abstract: A damper device for providing a braking force includes a cylinder member having an inner wall, and a piston member slidably disposed in the cylinder member, the braking force being generated by movement or relative movement of the piston member. The piston member includes a seal member having an attachment base, and a lip portion extending from the attachment base and contacting the inner wall of the cylinder member, and a bending regulation portion assembled with the seal member for regulating an outer surface of the attachment base of the seal member.

Abstract: A damper comprises a pressure tube extending longitudinally between a first pressure tube end and a second pressure tube end, a piston arranged in sliding engagement inside the pressure tube, a piston rod coupled to the piston, a hydraulic rebound stop positioned in a first working chamber and including a sealing ring circumferentially extending around the piston rod and within the pressure tube. The sealing ring at least partially defining a high-pressure region within the pressure tube during a rebound stroke the damper further comprising a pressure relief valve in fluid communication with the high-pressure region. The pressure relief valve being operable to allow pressurized fluid from the high-pressure region to pass therethrough once a predefined pressure threshold has been reached.

Abstract: A damper assembly includes a pressure tube defining a chamber. The damper assembly includes a body supported by the pressure tube. The body has a first surface and a second surface opposite and spaced from the first surface along an axis. The body defines a passage extending from the first surface to the second surface. The damper assembly includes an orifice disc movable from an unflexed position to a first flexed position and movable from the first flexed position to a second flexed position. The orifice disc in the unflexed position is spaced from the first surface radially outward and radially inward of the passage. The orifice disc in the first flexed position is spaced from the first surface radially outward of the passage and abuts the first surface radially inward of the passage. The orifice disc in the second flexed position abuts the first surface radially outward and radially inward of the passage.

Abstract: A shock absorber for a wheel suspension of a vehicle may include an outer cylinder, an outer piston that is axially displaceably guided in the outer cylinder, an inner piston that is axially displaceably guided in the outer piston, and a piston rod that is connected to the inner piston and that is guided out of the outer piston. A surface, which is located remote from the piston rod, of a piston portion of the outer piston, which is axially displaceably guided on an inner lateral surface of the outer cylinder, is connected so as to communicate partially with surroundings of the shock absorber.

Abstract: An intermediate cylinder is disposed between an outer cylinder and an inner cylinder. The intermediate cylinder forms a passage between the inner cylinder and itself, through which a hydraulic fluid as an electrorheological fluid flows. The intermediate cylinder is supplied (applied) with a voltage through an electrode connector. The intermediate cylinder includes a ring member. The ring member is provided with an extending portion which extends toward the outer cylinder. The extending portion of the ring member is inserted with an electrode pin as an imparting unit for imparting a voltage to the intermediate cylinder.

Abstract: In a shock absorber, an outer case made of resin is disposed so as to cover an inner case made of metal, and the outer case forms a reservoir chamber for storing the hydraulic fluid between the outer case and the inner case. The outer case is supported by the inner case via protrusions, which are formed on either one of the outer peripheral surface of the inner case and the inner peripheral surface of the outer case so as to protrude toward and abut the other one of the outer peripheral surface of the inner case and the inner peripheral surface of the outer case.
