摘要： A temperature compensating system (10) for a closed system, such as damping system (12), in which fluid is subject to temperature increases and acocmpanying volume increases. The temperature compensation system provides a compressible member (40) within a temperature compensation volume, and a barrier (46) restricting the entry of fluid to the volume. When the fluid volume increases as a result of temperature increases, fluid seeps past the barrier into the temperature compensation volume to compress the compressible member and thus increase the total volume available to the fluid in the closed system. The increased volume reduces pressure buildup that would otherwise occur, and thereby tends to maintain a steady pressure within the closed system. Dynamic or high speed fluid flows are restricted by the barrier or other restriction, inhibiting such flows from passing into the volume. The barrier or other restriction thus tends to prevent the temperature compensating system from interfering with normal functioning of the system while maintaining a steady internal pressure therein.

摘要： A bicycle suspension fork (10) having a primary compression spring assembly (50) positioned in only one of the fork legs (14, 16). A load distributing assembly (52) is positioned in at least one of the fork legs (14, 16) in order to distribute loads transmitted to the fork (10) during a compression stroke. Thus, asymmetrical loading that would occur from the presence of only one compression spring assembly (50) on only one side of the fork is decreased if not completely eliminated. The load distributing assembly (52) preferably is arranged such that it begins load distribution during the last one-half, and most preferably the last one-third of compression stoke travel. A preferred embodiment of the load distributing assembly (52) includes a load distributing spring (80) and a load distributing spring spacer (82).

摘要： A suspension system (10) for a bicycle or other vehicle or apparatus, the system including at least one telescoping strut comprising a first telescoping member (12) and a second telescoping member (14), the first and second telescoping members being telescopingly and coaxially engaged with each other so that the strut is compressible by relative movement of the telescoping members toward each other and expandable by relative movement away from each other. A piston (16) may be interconnected with the second telescoping member and slidably positioned within the first telescoping member. The piston separates a primary compression spring chamber into two gas chambers (30, 34) connected by an adjustable port, whereby compression or expansion of the strut creates a damping force that resists such relative movement of the telescoping members, resulting in the primary compression spring having a frequency-sensitive spring rate. The crack force, spring rate and other characteristics of the suspension system may be adjusted using a piston location adjuster to adjust the piston height, and/or a negative preload spring to apply a compressive preload force to the telescoping strut.
