Abstract
Disclosed herein is an accumulator comprising a cylinder, and an internal floating piston. The internal floating piston divides the cylinder into a spring chamber and a gas chamber, and the spring chamber allows fluid to flow. The accumulator further comprises a negative spring disposed in the spring chamber.
Claims17
An accumulator comprising:
- a cylinder;
- an internal floating piston, to divide the cylinder into a spring chamber and a gas chamber, the spring chamber to allow fluid to flow, wherein any movement of said internal floating piston to move further into said gas chamber is based upon a fluid pressure on a side of said internal floating piston which does not face said gas chamber;
- and
- a negative spring disposed in the spring chamber, said negative spring having a spring force such that a force on said internal floating piston from said gas chamber and a force from said negative spring are balanced.

2 more elements
A cross-linked system comprising:
- a first shock assembly;
- a second shock assembly;
- a first line fluidly coupled with a first rebound chamber of the first shock assembly and a second compression chamber of the second shock assembly, to allow fluid to flow between the first rebound chamber and the second compression chamber;
- a second line fluidly coupled with a first compression chamber of the first shock assembly and a second rebound chamber of the second shock assembly, to allow fluid to flow between the first compression chamber and the second rebound chamber;
- a reservoir, wherein the reservoir fluidly coupled to the first line and the second line;
- and
- an accumulator fluidly coupled to said first line and said second line, said accumulator comprising:
- a cylinder;
- an internal floating piston, to divide the cylinder into a spring chamber and a gas chamber, the spring chamber to allow fluid to flow, wherein any movement of said internal floating piston to move further into said gas chamber is based upon a fluid pressure on a side of said internal floating piston which does not face said gas chamber;
- and
- a negative spring disposed in the spring chamber, said negative spring having a spring force such that a force on said internal floating piston from said gas chamber and a force from said negative spring are balanced.
