Abstract
An adjustable shock assembly is disclosed herein. The adjustable shock assembly includes a damper body having a main chamber with a working fluid therein. An adjustable active valve assembly comprising: a first parallel flow pathway comprising an active valve; and a second parallel flow pathway comprising a firm mode blowoff stack and a firm mode adjuster to adjust a blowoff pressure of the firm mode blowoff stack. A main piston coupled with a piston shaft, and a fluid pathway fluidly coupling the main chamber with the adjustable active valve assembly which is fluidly coupled with a reservoir.
Claims20
An adjustable shock assembly comprising:
- a damper body comprising a main chamber with a working fluid therein;
- an adjustable active valve assembly comprising:
- a first parallel flow pathway comprising an active valve;
- and
- a second parallel flow pathway comprising:
- a firm mode blowoff stack;
- and
- a firm mode adjuster to adjust a blowoff pressure of said firm mode blowoff stack, wherein said working fluid flows into said adjustable active valve assembly, a portion of said working fluid passes through said first parallel flow pathway, a different portion of said working fluid passes through said second parallel flow pathway, and said working fluid joins back together to exit said adjustable active valve assembly;
- a main piston coupled with a piston shaft;
- and
- a fluid pathway, said fluid pathway fluidly coupling said main chamber with said adjustable active valve assembly which is fluidly coupled with a reservoir.
8 more elements
An adjustable shock assembly comprising:
- a damper body comprising a main chamber with a working fluid therein;
- a compression adjuster comprising:
- at least a first parallel flow pathway comprising an adjustable valve;
- and
- at least a second parallel flow pathway comprising a compression valve stack;
- an adjustable active valve assembly comprising:
- at least a first parallel flow pathway and a second parallel flow pathway, said first parallel flow pathway comprising an active valve;
- and
- said second parallel flow pathway comprising:
- a firm mode blowoff stack;
- and
- a firm mode adjuster to adjust a blowoff pressure of said firm mode blowoff stack, wherein said working fluid flows into said adjustable active valve assembly, a portion of said working fluid passes through said first parallel flow pathway, a different portion of said working fluid passes through said second parallel flow pathway, and said working fluid joins back together to exit said adjustable active valve assembly;
- a main piston coupled with a piston shaft;
- and
- a fluid pathway, said fluid pathway to fluidly couple said main chamber with said compression adjuster and said adjustable active valve assembly, and fluidly couple one or both of said compression adjuster and said active valve assembly with a reservoir.
12 more elements
An adjustable shock assembly comprising:
- an air sleeve;
- a damper body comprising a main chamber with a working fluid therein;
- a compression adjuster comprising:
- at least a first parallel flow pathway comprising an adjustable valve;
- and
- at least a second parallel flow pathway comprising a compression valve stack;
- an adjustable active valve assembly additively coupled in series with said compression adjuster, said adjustable active valve assembly comprising:
- a first parallel flow pathway comprising an active valve to automatically control a flow rate of working fluid therethrough;
- a second parallel flow pathway comprising:
- a firm mode blowoff stack to control a flow rate of working fluid therethrough;
- and
- a firm mode adjuster to manually adjust a blowoff pressure of said firm mode blowoff stack and adjust a compression characteristic of said adjustable shock assembly;
- and
- an externally adjustable feature coupled with said firm mode adjuster, said externally adjustable feature manually manipulatable to adjust a blowoff pressure of said firm mode blowoff stack thereby modifying a damping characteristic of said adjustable active valve assembly, wherein said working fluid flows into said adjustable active valve assembly, a portion of said working fluid passes through said first parallel flow pathway, a different portion of said working fluid passes through said second parallel flow pathway, and said working fluid joins back together to exit said adjustable active valve assembly;
- a main piston coupled with a piston shaft;
- and
- a fluid pathway, said fluid pathway to move said working fluid from said main chamber, through said adjustable active valve assembly and into a reservoir during a compression stroke when said piston shaft causes an amount of said working fluid to become shaft-displaced working fluid.
