Abstract
Solar tracker systems include a torque tube, a solar panel attached to the torque tube, and a damper assembly. The damper assembly includes an outer shell, a first chamber wall and a second chamber wall within the outer shell at least partially defining a chamber, and a piston to direct fluid through the chamber. A valve is within the chamber that includes a first axial end, a second axial end, and a seal positioned on the first axial end. The damper assembly further includes a biasing assembly that biases the valve into a first position within the chamber in which the seal is spaced from the first chamber wall. The valve is moveable within the chamber from the first position to a second position in which the seal contacts and seals against the first chamber wall to prevent the flow of fluid through the chamber.
