A bump cap includes: a tubular main body part; and three or more protrusions provided at different positions in a circumferential direction of an inner circumference of the main body part. A plurality of protrusions are press-fit protrusions having a radial height higher than a radial height of the other protrusions, and the number of the press-fit protrusions are smaller than the number of the other protrusions, and the bump cap is configured to be mounted on an outer circumference of an outer shell of a shock absorber in state where the press-fit protrusions are pushed against the outer circumference of the outer shell.

A pressure stop cap for a motor vehicle vibration damper includes a disk-shaped end portion which is formed in an end area of the pressure stop cap and forms a rebound surface for an impact absorber, a tubular portion extending axially from the disk-shaped end portion, and at least one vent opening which is arranged adjacent to the end portion in the end area of the pressure stop cap and extends radially through the tubular portion. The pressure stop cap has a groove-like circumferential recess which is formed at its outer surface and which divides the outer surface of the pressure stop cap axially into a first pressure stop cap portion and a second pressure stop portion, the first pressure stop cap portion being formed in the area of the end portion. The cross section of the first pressure stop cap portion is larger than the cross section of the pressure stop cap in the area of the circumferential recess, and the cross section of the second pressure stop cap portion is larger than the cross section of the pressure stop cap in the area of the circumferential recess.

A vehicle strut assembly includes a boot and a coil spring. The boot has a vertical wall, a spring receiving portion and a centering portion projecting from the vertical wall. The coil spring has an end section, a transition section and a main section, the end section being fitted to the spring receiving portion encircling at least a portion of the vertical wall and defining a first radially inner diameter. The transition section has an increasing inner diameter extending from the end section to the main section. The main section defines a second radially inner diameter greater than the first radially inner diameter. The centering portion is positioned to contact a radially inner surface of the transition section of the coil spring restricting movement of the end section of the coil spring relative to the spring receiving portion of the boot.

A strut assembly including a reservoir tube that extends about and along a center axis and has an interior surface and defines a chamber. A bearing sleeve is disposed in the chamber of the reservoir tube and extends about and along the center axis between a proximal end and a distal end. The bearing sleeve presents an inner surface and an outer surface. A damper body tube is disposed in the bearing sleeve and is moveable relative to the bearing sleeve. A piston assembly is disposed in the damper body tube. The outer surface of the bearing sleeve has a tubular portion and a protrusion portion that extends radially outwardly relative to the tubular portion and annularly and providing an interference fit between the outer surface of the bearing sleeve and the interior surface of the reservoir tube.

A method for manufacturing a magnetic valve and a corresponding magnetic valve, in particular for the use for electrically continuously adjustable shock absorbers of a vehicle. A valve housing and a magnetic armature which is movably supported relative to a longitudinal axis of an electrically energizable coil and which is at least partially surrounded by a pole tube which is at least partially surrounded by a coil body of the coil that in turn is cast with a casting compound, provides a corrosion protection cap covering an axial end of the pole tube. The corrosion protection cap establishing a connection to the casting compound and protecting the axial end of the pole tube against corrosion influences from the atmosphere.

An air spring having an airsleeve, wherein at least one layer of said airsleeve includes the vulcanization product of a composition that includes at least one vulcanizable polymer, a curative, at least one halogenated hydrocarbon wax, and expandable graphite.
