Modular active valve system having a reduced footprint for use in a smaller shock platform
A modular active valve system having a reduced footprint for use in a smaller shock platform is disclosed. The modular active valve system includes a multi-stage valve having a first stage and at least a second stage, wherein at least the first stage includes a semi-active valve for electronic damping control.
1. A multi-stage valve comprising:
a first stage; and
at least a second stage,
wherein at least the first stage comprises a semi-active valve for electronic damping control, and
wherein:
the first stage comprises a pilot valve;
the second stage comprises a main relief valve;
the pilot valve configured to provide an electronically adjustable fluid pressure to the main relief valve;
the main relief valve configured to modify a firmness of a damper based on the electronically adjustable fluid pressure received from the pilot valve; and
a third stage comprising a boost cylinder, the boost cylinder configured to modify said firmness of said damper based on the electronically adjustable fluid pressure received from the pilot valve, said boost cylinder further comprising:
a shim stack comprised of a plurality of shims; and
a clamp configured to contact at least one of said plurality of shims, wherein a damping range of said boost cylinder is adjusted by modifying which of said plurality of shims is in contact with said clamp.
2. A multi-stage base valve comprising:
a first stage; and
at least a second stage,
wherein at least the first stage comprises a semi-active valve for electronic damping control, and the second stage comprises a boost cylinder;
the first stage configured to provide an electronically adjustable fluid pressure to the boost cylinder; and
the boost cylinder configured to modify a firmness of a damper based on the electronically adjustable fluid pressure received from the first stage, said boost cylinder further comprising:
a shim stack comprised of a plurality of shims; and
a clamp configured to contact at least one of said plurality of shims, wherein a damping range of said boost cylinder is adjusted by modifying which of said plurality of shims is in contact with said clamp.
3. The multi-stage base valve of claim 2 wherein the first stage is a spool type pilot valve.
4. The multi-stage base valve of claim 2 wherein the first stage is a poppet type pilot valve.
5. A multi-stage valve comprising:
a first stage; and
at least a second stage,
wherein at least the first stage comprises a semi-active valve for electronic damping control, and
wherein:
the first stage comprises a pilot valve;
the second stage comprises a boost cylinder;
the pilot valve configured to provide an electronically adjustable fluid pressure to the boost cylinder; and
the boost cylinder configured to modify a firmness of a damper based on the electronically adjustable fluid pressure received from the pilot valve, said boost cylinder further comprising:
a shim stack comprised of a plurality of shims; and
a clamp configured to contact at least one of said plurality of shims, wherein a damping range of said boost cylinder is adjusted by modifying which of said plurality of shims is in contact with said clamp.
6. The multi-stage valve of claim 5 , further comprising:
a third stage comprising a main relief valve, the main relief valve configured to modify said firmness of said damper based on the electronically adjustable fluid pressure received from the pilot valve.
