Claims6
A vehicle suspension damper comprising:
- a primary valve;
- a pilot valve assembly, said pilot valve assembly comprising:
- an adjustable pilot spool configured for controlling a pressure inside said primary valve;
- a bleed passage;
- and
- a flow control orifice for limiting flow through into said bleed passage;
- an externally-adjustable adjuster, wherein said pilot valve assembly meters fluid to said primary valve, and movement of said externally-adjustable adjuster varies an effective orifice size of said adjustable pilot spool, said externally-adjustable adjuster disposed at a top cap of said vehicle suspension damper, and wherein said adjuster moves said primary valve in response to a current delivered from a power source;
- and
- a set of shims coupled to said primary valve, wherein a position of said adjustable pilot spool corresponds to an increase of pressure inside said primary valve and an increase of an axial force on said set of shims by said primary valve.
