Abstract
A suspension system includes a first compression chamber and a second compression chamber with a damping chamber therebetween. The compression chambers may be independently filled with a compressible fluid, and the relative pressures may govern the rebound rate of the suspension. Seals that minimize friction, an adjustment system, and a stop are also included to enhance rider joy.
Claims12
A shock absorber comprising:
- a first end including at least a first tube at least partially defining a first compression chamber filled with a compressible fluid;
- a first Schrader valve extending between an exterior of the first tube and an interior of the first tube and permitting the compressible fluid to be removed from the first compression chamber and permitting additional compressible fluid to be added to the first compression chamber;
- a second end including at least a second tube at least partially defining a second compression chamber and a first damping chamber, each filled with the compressible fluid;
- a second Schrader valve extending between an exterior of the second tube and an interior of the second tube and permitting the compressible fluid to be removed from the second compression chamber and permitting additional compressible fluid to be added to the second compression chamber;
- a third valve between the second compression chamber and the first damping chamber, permitting compressible fluid to flow between the second compression chamber and the first damping chamber;
- and
- an adjuster capable of adjusting a threshold at which the third valve opens to allow compressible fluid to flow between the second compression chamber and the first damping chamber.
