摘要： Solar tracker systems include a torque tube, a column supporting the torque tube, a solar panel connected to the torque tube, and a locking assembly. The locking assembly includes a first end pivotably connected to the torque tube and a second end pivotably connected to the column. A shell defines a fluid chamber and a piston is positioned within the shell. The piston includes a seal and defines compression and extension portions of the fluid chamber. A flow path extends between the compression portion and the extension portions. A first valve assembly controls fluid flow in a first direction through the flow path and a second valve assembly controls fluid flow in a second direction through the flow path. The valve assemblies are each passively moveable from an unlocked state to a locked state in response to movement of the piston.

摘要： A bumper cap for a damper, the damper including an outer tube with a tube end. A rod extending through the tube end. The damper including a damping fluid, such as a hydraulic oil, that is movable within the damper in response to movement of the rod to provide a damping effect. The bumper cap has a cup shaped body having a side wall and a base, the side wall having an inner surface and an outer surface, the inner surface having a dimension that is sized to be press fit over the outer tube. The base of the bumper cap has a through hole in the base, the through hole configured to have the rod pass therethrough. The base has at least one fluid passage extending away from the through hole that is in fluid communication with a fluid reservoir in the side wall.

The dirt ingress seal comprising a first lip (102a) that isolates the internal space of the seal (100) from the atmosphere and external environment; first ribs (105a) formed on the inner side of the circumferential surface of the dirt ingress seal (100), the first ribs (105a) formed near the first lip (102a); a second lip (102b) provided on the inner circumferential portion near the central region of the dirt ingress seal (100); second ribs (105b) defining cavities; and cavities defined by the first ribs (105a). The cavities are configured to arrest and trap mud, dust, dirt, and particulate matter entering the sealed zone and preventing further ingress of abrasive particles into the seal zone. The seal (100) increases the sealing effectiveness and useful life of seals, shock absorber, and front forks.

摘要： A piston and cylinder type damper having a cylinder (12) containing damping fluid with a piston assembly (10) mounted therein for reciprocal movement along a linear axis, with the piston assembly (10) dividing the cylinder (12) into two separate chambers (A, B). A mechanism is provided for controlling flow of damping fluid between said chambers (A, B), the control mechanism comprising a sealing element (17) movable axially with respect to the piston assembly (10). The piston assembly (10) comprises end stops (19, 20) for limiting said relative axial movement of the sealing element (17), with the sealing element (17) acting on engagement with a first one of said end stops (20) to constrain flow of damping fluid to a restricted passageway in the piston assembly. The first end stop (20) is provided as a separate component.

摘要： A damping assembly (100) for a structure includes a housing (104) with a first fixed end (108) and a second movable opposite end (112). A first translatable portion of the housing (104) is slidably movable relative to an adjacent second section (120) of the housing (104), the former being fixedly secured to a base when the structure is under load. A viscous damper disposed within the housing (104) is engaged only after the first translatable section has first moved beyond an initial predetermined distance indicative of a higher amplitude loading event. At least one biasing feature (180) prevents the viscous damper from operating until the first translatable section has first moved beyond the initial predetermined distance.
