Abstract

Methods and apparatus for regulating the function of a suspension system are disclosed herein. Suspension characteristics often contribute to the efficiency of a suspended system. Depending on the desired operating parameters of the suspended system, it may be desirable to alter the functional characteristics of the suspension from time to time in order to maintain or increase efficiency. The suspension hereof may be selectively locked into a substantially rigid configuration, and the damping fluid may be phase separated and/or cooled to increase damping rate during use (or offset rate degradation). The suspension hereof may generate power usable to achieve any or all of the foregoing or to be stored for use elsewhere in the suspended system or beyond.

Claims (6)

1. A vehicle suspension comprising:

a first support member;

a second support member, said first support member and said second support member being movable relative to one another along a substantially common axis, wherein a damper having a damping fluid is disposed between said first support member and said second support member; and

a valve assembly configured for one of opening and closing in response to an electric current, said valve assembly comprising:

a sensor, wherein said sensor is configured for sensing a change in a characteristic of said damping fluid caused by said relative movement between said first support member and said second support member and for responding such that said electric current is generated.

2. The vehicle suspension of claim 1 , wherein said responding comprises: deforming.
