A movement stage for a hydraulic shock absorber has a damping volume and a stage throttle with a valve disk, an analogue piston, and an elastic biasing means supported on the analogue piston and on the valve disk. The valve disk has a pressure surface defining a portion of the surface of a disk valve arranged upstream of an entry edge of a disk valve seat. The analogue piston has a pressure surface facing away from the biasing means. The valve disk pressure surface and the analogue piston pressure surface are impinged by damping fluid flowing out of the damping volume as the shock absorber moves in a movement direction. The analogue piston pressure surface is larger than the valve disk pressure surface when projected in the closing direction of the disk valve so that the analogue piston is displaced and the bias of the valve disk increases.

A method of manufacturing a gas cylinder according to an embodiment of the present invention may include applying a sealant to at least a portion of inner surface of a hollow spindle; inserting a cylinder assembly contacting the inner surface of the spindle through an inlet of the spindle and forming a sealant film on an inner surface of the spindle by frictionally applying the sealant to the inner surface of the spindle; and hardening the sealant film to form a cured film cylinder in contact with the inner surface of the spindle.

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 solar tracker system includes a support tube, a solar panel assembly connected to the support tube, and an active lock connected to the support tube. The active lock includes a housing defining a chamber and a seal. The seal prevents a flow of fluid through the chamber when the active lock is in a sealed state and allows the flow of fluid through the chamber when the active lock is in an unsealed state. The active lock further includes a locking system motor connected to the seal to transition the active lock between the sealed state and the unsealed state, a battery providing power to the locking system motor, and an antenna for receiving instructions controlling the locking system motor.

A vibration damper with an adjustable damping force may comprise an inner cylinder having at least one working chamber, an outer cylinder that surrounds the inner cylinder, and at least one damping valve element that in terms of flow is connected via a flow connection to the working chamber. An adapter sleeve may guide the flow connection, with the adapter sleeve being inserted in the inner cylinder on an internal circumference of the inner cylinder. The flow connection may be guided into the damping valve element by way of a flow opening that is configured in a wall of the inner cylinder.

The invention relates to a vibration damper for a motor vehicle comprising an inner tube, an outer tube and at least one compensating chamber, which is formed between the inner tube and the outer tube and comprises at least one gas bag, which is arranged in the compensating chamber, wherein the compensating chamber is fluidically connected to at least one working area of the inner tube filled with a hydraulic fluid, wherein at least one guide element is provided, which deflects a flow of the hydraulic fluid during a rebound stage or a compression stage in such a way that the gas bag is indirectly subjected to flow. Furthermore, the invention relates to a motor vehicle.

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.

Described herein is a fluid flow control device comprising: a central structure, a main piston disposed around the central structure, wherein the main piston has at least one vent, a boost valve, wherein the boost valve has a gap fit to receive fluid, a shim stack disposed between the main piston and the boost valve such that the at least one vent is covered, a piston disposed on top of the gap of the boost valve, a spring disposed to bias the piston against the boost valve, and a pilot chamber running through the central structure, the pilot chamber fluidly coupled to the gap.

A bracket comprises a body extending along a center axis between a first end and a second end. The body defines a first groove and a second groove. The first groove, located at the first end and flaring radially outwardly, presents a first slanted surface. The second groove, located at the second end and flaring radially outwardly, presents a second slanted surface. A pair of coupling members including a first and a second coupling member are respectively located in the first and second grooves for engagement with a housing of a hydraulic damper assembly. The first end includes at least one first deformation for retaining the first coupling member. The second end includes at least one second deformation for retaining the second coupling member. A hydraulic damper assembly including the bracket and a method of joining the bracket and the hydraulic damper assembly are also disclosed herein.

A magneto rheological damper includes a housing extending between a first opened end and a second opened end and defining a fluid chamber extending therebetween. An end cap is located at the first opened end and coupled to the housing. A piston is disposed in the fluid chamber dividing the fluid chamber into a compression chamber and a rebound chamber. A piston rod extends along the center axis and attaches to the piston for movement with the piston between a compression and a rebound stroke. A magnetic field generator is located in the compression chamber and in an abutment relationship with the end cap. An extension portion protrudes radially outwardly from the housing and defining a compensation chamber and a channel. The channel is in fluid communication with the compression chamber and the compensation chamber for allowing the working fluid to flow from the compression chamber to the compensation chamber.
