A damper assembly comprises a main tube defining a fluid chamber. The main tube includes a first section, a second section, and an intermediate portion. A sleeve is disposed about the main tube. An external tube is disposed about the main tube and the sleeve. The external tube defines a compensation chamber between the sleeve and the external tube. A main piston divides the fluid chamber into a rebound chamber and a compression chamber. A piston rod couples to the main piston for moving the main piston between a compression stroke and a rebound stroke. The sleeve is in an abutment relationship with the second section of the main tube, radially spaced apart from the first section of the main tube, defining a compartment extending between the sleeve and the first section of the main tube. A housing for the damper assembly is also disclosed herein.

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.

An air spring includes a first body; a first piston cooperating with the first body to define a pressurized first chamber including a gas, the first piston configured to slideably move relative to the first body; a pressurized second chamber; a flow passage between the first chamber and the second chamber; and a seal to selectively permit or restrict flow between the first chamber and the second chamber depending on a position of the first piston with respect to the first body.

A damper for a telescopic fork leg for a front fork of a vehicle, wherein the damper comprises a twin-tube cylinder and a piston rod assembly comprising a piston rod, wherein a first piston is attached to the inner end portion of the piston rod, wherein a second piston is attached to the piston rod between the first piston and an outer end portion of the piston rod, wherein the inner tube is provided with at least one outlet hole 19 through the wall of the inner tube, the outlet hole being positioned such that a sealing portion of the second piston at compression of the damper travels past at the at least one outlet hole, and wherein the inner tube is provided with at least one return hole through the wall of the inner tube, the at least one return hole being positioned such that it connects a chamber of the twin-tube cylinder to an outer volume of the cylinder.

A combination gas spring and shock absorber apparatus includes a vented gas spring housing and a vented shock absorber housing slidably mounted within the gas spring housing. A shock absorber piston is concentrically mounted within a gas spring piston. A base housing is slidably mounted in the gas spring housing. A shaft extends through the base housing and into the shock absorber housing. The shock absorber piston is mounted in the shock absorber housing on the free end of the shaft. The gas spring piston is mounted in the gas spring housing on the distal end of the base housing. The shock absorber piston is fluidically sealed and slides within the shock absorber housing. The gas spring piston is fluidically sealed and slides along the gas spring housing and the shock absorber housing. The base housing telescopically translates relative to the gas spring housing.

A shock absorber including a pressure tube, a piston assembly slidably disposed within the pressure tube, and a fluid transfer tube that extends about the pressure tube, and a reserve tube that extends about the fluid transfer tube is provided. The piston assembly divides an inner volume of the pressure tube into first and second working chambers. An intermediate chamber between the pressure tube and the fluid transfer tube is arranged in fluid communication with the first working chamber. A reservoir chamber between the fluid transfer tube is arranged in fluid communication with the intermediate chamber. An insert is disposed within the intermediate chamber, reducing the volume of the intermediate chamber and defining a fluid transfer channel between the first working chamber and the reservoir chamber.

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.

A solar tracker system includes a torque tube, a solar panel assembly attached to the torque tube, a housing defining a chamber and a fluid passageway extending from the chamber, and an active lock connected to a seal configured to prevent a flow path of fluid while in a sealed state and allow the flow path of fluid in an unsealed state. The system further includes a controller in communication with the torque tube and the active lock. The controller is programmed to receive a command to place the solar panel assembly in a stowed position, instruct the torque tube to rotate the panel assembly to a stowed angle corresponding to the stowed position, monitor a current angle of the panel assembly, compare the current angle to the stowed angle, and instruct the seal to transition to the sealed state when the current angle is equal to the stowed angle.

A manufacturing method for a cylinder device which includes a cylinder, a piston, a piston rod, a seal member, and an installing member, the method includes: a welding step for fixing the installing member to the cylinder through electrical resistance welding; a demagnetizing step for demagnetizing at least an opening portion of the cylinder; and an assembling step for assembling the piston, the piston rod, and the seal member in the cylinder through the opening portion.
