Abstract

A shock absorber including: a first cylinder having an interior, first and second ends and defining an axis, wherein the interior includes a damping fluid chamber and a damping piston movably mounted therein for movement between the first and second ends, wherein the damping piston is mounted on a first end of a shaft, wherein the first end of the shaft is movably retained within the interior of the first cylinder; first and second bypass openings configured for opening into the damping fluid chamber at first and second axially spaced-apart positions; a bypass channel fluidly coupling the first and second bypass openings; a fluid metering valve; and a floating piston dividing a portion of the shock absorber into a gas chamber and the reservoir chamber, wherein the fluid metering valve and the floating piston define the reservoir chamber there between.

Claims (12)

1. A shock absorber comprising:

a cylinder having an interior and a cylindrical axis, said cylinder having a first end and a second end, wherein said interior comprises a damping fluid chamber and a damping piston, said damping piston mounted on a first end of a shaft, wherein said first end of said shaft is retained within said interior of said cylinder and movable along at least a portion of said cylindrical axis such that said damping piston is movable within said interior of said cylinder between said first end of said interior of said cylinder and said second end of said interior of said cylinder;

a first bypass opening configured for opening into said damping fluid chamber at a first axial position of said cylinder;

a second bypass opening configured for opening into said damping fluid chamber at second axial position of said cylinder, said first axial position and said second axial position being spaced apart from each other;

a bypass channel fluidically coupling said first bypass opening and said second bypass opening;

a reservoir chamber;

a gas chamber;

a floating piston disposed separating said gas chamber and said reservoir chamber;

a fluid metering valve disposed to meter fluid flow between said damping fluid chamber and said reservoir chamber; and

an air spring.

2. The shock absorber of claim 1 , wherein said shock absorber further comprises:

a coiled spring, wherein said coiled spring provides resistance during a compression stroke of said shock absorber.
