Patent ID: 8827292

Claim:
A cylinder shock assembly, comprising: a damper having a first end and a second end, wherein the first end includes a first mount and the second end of the damper extends into an air cylinder float; the damper includes a housing defining a cavity, the damper having a rod positioned in the air cylinder float, the rod having a first end positioned within the cavity of the damper and a second end affixed to an end cap that is connected to a first end of the air cylinder float; a first piston affixed to the first end of the rod within the cavity of the damper, a second piston affixed to the damper, the second piston having one or more seals on an outer surface thereof that sealingly engage an inner surface of the air cylinder float; a primary coil spring positioned within the air cylinder float and about the rod and positioned between the second piston and the end cap; wherein when a load applied to the cylinder shock assembly is increased, the second piston and the second end of the damper move towards the end cap compressing air within the air cylinder float; wherein as the load is increased the primary coil spring is compressed and the volume of air within the air cylinder decreases resulting in an increased air pressure; wherein the primary coil spring and the volume of air within the air cylinder float provide an effective spring rate for the cylinder shock assembly; and wherein the air cylinder float is a solid member that does not expand as the air pressure within increases during compression.
