摘要： A damper including inner and outer tubes is provided. A piston is slidably disposed within the inner tube. An intermediate tube is positioned radially between the inner and outer tubes. The intermediate tube extends between first and second intermediate tube ends. An intermediate channel is disposed radially between the intermediate and inner tubes. A slanted elliptical seal is positioned inside the intermediate channel and divides the intermediate channel into first and second intermediate channel portions. A first control valve is in fluid communication with the second intermediate channel portion via a first intermediate tube opening. A second control valve is in fluid communication with the first intermediate channel portion via a second intermediate tube opening. The slanted elliptical seal abuts the intermediate tube between the first intermediate tube opening and the first intermediate tube end and between the second intermediate tube opening and the second intermediate tube end.

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.

摘要： A sealing ring includes a first sealing element having a first mating surface and a second sealing element having a second mating surface. A high-pressure boundary extends across at least a portion of the first sealing element and across at least a portion of the second sealing element, and
a low-pressure boundary extends across at least a portion of the first sealing element and across at least a portion of the second sealing element. The first mating surface, the second mating surface, or both, includes a recess open to the low-pressure boundary and not open to the high-pressure boundary. The recess may include a groove, for example. The first mating surface is sealed against the second mating surface by a first force acting on the first sealing element and a second force acting on the second sealing element. These forces act to pressure-lock the assembly.-

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 universal tube adaptor for a shock absorber includes a connector body, and first and second connectors. The connector body has intersecting first and second connecting holes respectively and rotatably receiving the first and second connectors rotatably therein. The first connector has a first guiding hole and an overflow hole perpendicular to, in fluid communication with, and cooperating with the first guiding hole to define an oil-filled space in fluid communication with the second connecting hole. The second connector has a second guiding hole in fluid communication with the second connecting hole and the overflow hole, so that the second guiding hole, the oil-filled space and the first guiding hole cooperate with one another to define an oil passage permitting damping oil to flow therein.

摘要： A damper includes a pressure tube extending about a longitudinal axis and defining an inner volume. The damper includes a piston attached to a piston rod and slidably disposed within the pressure tube. The piston divides the inner volume of the pressure tube into a first working chamber and a second working chamber. The damper includes a fluid connector having a first wall and a second wall, each elongated along the longitudinal axis and sealed to the pressure tube. The fluid connector has a third wall elongated along the longitudinal axis and extending from the first wall to the second wall. The pressure tube defines an opening at the first working chamber, and the third wall of the fluid connector defines an opening spaced from the opening of the pressure tube. The first wall, the second wall, and the third wall define a passage extending from the opening of the pressure tube to the opening of the third wall.

摘要： A damper assembly includes a damper, an accumulator, and a tube mount. The damper includes a tube having an outer surface. The tube defines a central axis and a first cavity in the outer surface. The accumulator has an end defining a second cavity. The accumulator defines a longitudinal axis. The tube mount is attached to the outer surface of the tube around the first cavity. The tube includes a damper fluid. The end of the accumulator is supported by the tube mount to allow the damper fluid to flow from the tube through the first cavity and into the accumulator through the second cavity. The longitudinal axis of the accumulator is transverse to the central axis of the tube.

摘要： The damper assembly includes a tubular member, a rod, a primary piston, a secondary piston, and a resilient member. The tubular member includes a sidewall and a cap positioned at an end of the sidewall. The sidewall and the cap define an inner volume. The sidewall includes a shoulder separating the tubular member into a first portion and a second portion. The resilient member is disposed between the secondary piston and the cap and thereby is positioned to bias the secondary piston into engagement with the shoulder.
