1. An adjustable-volume gas-pressurized device for a two-wheeled vehicle, comprising:
- a main gas chamber and at least a first auxiliary gas chamber and a second auxiliary gas chamber; and
a rotary disc valve assembly comprising;
a plurality of discrete settings for controlling whether different combinations of said main gas chamber, and said at least said first auxiliary gas chamber and said second auxiliary gas chamber are in fluid communication, said plurality of discrete settings including;
a first discrete setting in which there is fluid communication between said main gas chamber and both of said first auxiliary gas chamber and said second auxiliary gas chamber;
a second discrete setting in which there is fluid communication between said main gas chamber and said second auxiliary gas chamber, and there is no fluid communication between said main gas chamber and said first auxiliary gas chamber;
a third discrete setting in which there is fluid communication between said main gas chamber and said first auxiliary gas chamber, and there is no fluid communication between said main gas chamber and said second auxiliary gas chamber; and
a fourth discrete setting in which there is no fluid communication between said main gas chamber and either of said first auxiliary gas chamber and said second auxiliary gas chamber; and
wherein said rotary disc valve assembly can be adjusted on-the-fly by a vehicle rider.

Abstract
A gas spring curve control valve for a adjustable-volume gas-pressurized device is described. The valve allows for selection from among at least four spring curves and can be packaged in small spaces/devices. In an exemplary embodiment of the invention, a rotary cam having grooves and lobes that interact with spring loaded ball bearings and an external adjuster knob are used to easily change the gas spring curve “on-the-fly” and with minimal user effort.
