Abstract
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.
Claims6
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.

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.
