Claim 0:
1. A piston system for controlling compression fluid flow and rebound fluid flow there through, said piston system comprising:
a first adjustable orifice, wherein said first adjustable orifice is adjustable to have a first area, wherein said first area of said first adjustable orifice is large enough to enable said rebound fluid flow having a first flow rate to flow through a first rebound flow path associated with a low speed rebound fluid flow and said first adjustable orifice is adjustable to have a second area, wherein said second area of said first adjustable orifice is not large enough to enable all of said rebound fluid flow having a second flow rate to flow through said first rebound flow path such that at least a portion of said rebound fluid flow having said second flow rate flows through a second rebound flow path associated with a high speed rebound fluid flow;
a second adjustable orifice, wherein said second adjustable orifice is adjustable to have a first area, wherein said first area of said second adjustable orifice is large enough to enable said compression fluid flow having a first flow rate to flow through a first compression flow path associated with a low speed compression fluid flow and said second adjustable orifice is adjustable to have a second area, wherein said second area of said second adjustable orifice is not large enough to enable all of said compression fluid flow having a second flow rate to flow through said first compression flow path such that at least a portion of said compression fluid flow having said second flow rate flows through a second compression flow path associated with a high speed compression fluid flow;
a first piston;
a second piston fluidically coupled with said first piston, wherein said first piston and said second piston each comprises at least a portion of said first rebound flow path, said second rebound flow path, said first compression flow path, and said second compression flow path;
a lockout plate/rebound check valve configured for controlling lockout fluid flow through a lockout flow path, wherein said lockout plate/rebound check valve is positionally adjustable and blocks fluid from flowing into a set of outer diameter passageways disposed within said first piston;
a blow-off valve positioned within said first piston, wherein said piston system enables independent adjustment of said low speed compression fluid flow, said high speed compression fluid flow, said low speed rebound fluid flow, and said high speed rebound fluid; and
two concentric knobs with concentric cams, a first of said two concentric knobs configured to control said low speed compression fluid flow, a second of said two concentric knobs configured to control said low speed rebound fluid flow, said first of said two concentric knobs coupled to a first rod wherein rotation of said first of said two concentric knobs causes said first rod to move in a direction parallel of a central axis of a damper in which said piston system is disposed, said second of said two concentric knobs coupled to a second rod wherein rotation of said second of said two concentric knobs causes said second rod to move in a direction parallel of said central axis of said damper in which said piston system is disposed.
