Abstract
The fluid circuit when in a first condition permits relatively free fluid flow in a first direction between variable volume chambers of the damper, while permitting only relatively restricted flow in an opposite, second direction. When in a second condition, the circuit permits relatively free flow of fluid in the second direction and only relatively restricted flow in the second direction. The circuit condition is changed by changing the position of a control valve which is subjected to fluid pressure differentials that may at times delay change in the position of the valve, and therefore change in the condition of the circuit.
