摘要： 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.

摘要： A hydraulic damper includes: a rod that is inserted into a cylinder containing liquid; a piston that is connected to the rod and partition the cylinder into a first liquid chamber and a second liquid chamber; a channel forming part having a channel between the first liquid chamber and the second liquid chamber; a valve part configured to open and close the channel and generate damping force; and a damping force changer including an inflow part into which the liquid flows and configured to change the damping force by using liquid pressure in the inflow part. The damping force changer includes: a pressure changing part that changes the liquid pressure in the inflow part by being deformed or displaced; a support part that supports the pressure changing part; and an inflow forming part that holds the support part and forms the inflow part jointly with the support part.

摘要： A damper assembly includes an inner tube and an outer tube enclosing respective first and second chambers and defining respective first and second side openings. The assembly includes a housing supported by the outer tube and having an open bottom with a lip extending radially inward. The assembly includes a unitary connector engaged with the first side opening and axially extending away from the inner tube through the second side opening and the open bottom. The unitary connector is radially spaced from the outer tube at the second side opening and from the housing above the inner surface. The unitary connector abuts an inner surface of the lip of the housing and defines passages open to the first chamber and to the second chamber. The unitary connector includes a valve seat surrounding one of passages.

摘要： An end-stop control valve can progressively add end-of-stroke damping resistance to complement the damping force provided by a main piston in a damper tube. The end-stop control valve may include a piston that is secured on a piston rod and selectively engages a catch piston, both of which are longitudinally movable within the damper tube. As the piston approaches the catch piston, an annular pocket of hydraulic fluid is created longitudinally and radially between the piston and the catch piston. As the piston continues to approach the catch piston, a cross-sectional area through which hydraulic fluid exits the pocket decreases, thereby gradually increasing the resistance of the end-stop control valve. In addition, a spring disc secured on the piston rod may contact a valve seat on the catch piston and provide resistance by elastically deforming in a longitudinal direction before the contact surfaces of the piston and catch piston engage.

摘要： A vibration damper for a motor vehicle includes an outer tube and an inner tube arranged coaxially within the outer tube. A guide unit closes the outer tube and the inner tube in each case at a first end. A bottom unit has a bottom valve. The bottom unit is arranged at a second end of the inner tube. The outer tube and the inner tube are deformed plastically, such that the guide unit is connected in a positively locking manner to the outer tube and the inner tube, and the inner tube being deformed plastically, such that the bottom unit is connected in a positively locking manner to the inner tube, and/or the outer tube and the inner tube is connected in an integrally joined manner to the guide unit, and the inner tube being connected in an integrally joined manner to the bottom unit.
