Abstract: A damping assembly for a structure includes a housing with a first fixed end and a second movable opposite end. A first translatable portion of the housing is slidably movable relative to an adjacent second section of the housing, the former being fixedly secured to a base when the structure is under load. A viscous damper disposed within the housing 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 prevents the viscous damper from operating until the first translatable section has first moved beyond the initial predetermined distance.

Abstract: A module for a braking system includes a movable housing configured to transfer a braking force from an input shaft to an output shaft, a first movable member slidably received within the housing and connected to the output shaft, a second movable member slidably received within the housing, a first resilient member biased between the first movable member and the second movable member, such that a force applied to the second movable member is applied to the first movable member via the first resilient member, and a second resilient member biased between the second movable member and the housing, such that a force applied to the housing is applied to the second movable member via the second resilient member. The first resilient member yields or compresses upon application of a first braking force to the input shaft, and the second resilient member yields or compresses after the first resilient member.

Abstract: A damper includes a cylinder, a piston, a piston rod, a rod-side fluid chamber, a piston-side fluid chamber, an annular fluid chamber, and a stopper mechanism. The cylinder includes an inner tube and an outer tube. The rod-side fluid chamber is defined by the piston in the inner tube on a lower end side. The piston-side fluid chamber is defined by the piston in the inner tube on an upper end side. The annular fluid chamber is between the inner and outer tubes. At least one communication hole communicates the rod-side fluid chamber with the annular fluid chamber. A communication passage communicates the rod-side fluid chamber with the annular fluid chamber. A check valve in the communication passage allows fluid to flow from the annular fluid chamber to the rod-side fluid chamber and disallows the fluid to flow from the rod-side fluid chamber to the annular fluid chamber.

The bottom section (101) has a bored disk shape, and the tube section (102) has a cylindrical shape extending from an outer circumferential side of the bottom section (101) in the axial direction. An elastic rubber section (91) has a minimum inner diameter section (137), diameter expanding sections (138), (139) which are disposed at each side in the axial direction of the minimum inner diameter section (137). A tube section adhering surface (126) is installed at outer circumferential side of a tube section (102). A cutout section (151) is at least partially formed at a bottom section adhering surface (128) fixed to the bottom section (101) and the tube section (102) side of an open surface at an opposite side in the axial direction, and a deepest section (155) of the cutout section (151) is shallower than a position in the axial direction of the minimum inner diameter section (137).
